md5, sha1, sha256, sha512: fix link error with partial libcrypto

[gnulib.git] / ChangeLog

2013-12-07  Pádraig Brady <P@draigBrady.com>

        md5, sha1, sha256, sha512: fix link error with partial libcrypto
        * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Only clear LIB_CRYPTO at
        init time, so that if early checks find crypto routines,
        while the last does not, then @LIB_CRYPTO@ is replaced correctly,
        avoiding link failures.

        md5, sha1, sha256, sha512: add gl_SET_CRYPTO_CHECK_DEFAULT
        This provides a new way to specify the default for
        gl_CRYPTO_CHECK, one that is reflected in the --help message.
        Emacs uses this, as well as the old way.
        This attempts to implement a suggestion by Pádraig Brady in
        <http://lists.gnu.org/archive/html/coreutils/2013-12/msg00080.html>.
        * m4/gl-openssl.m4(gl_SET_CRYPTO_CHECK_DEFAULT): New macro.
        (gl_CRYPTO_CHECK): Use it.  Mention the default in --help output.

        md5, sha1, sha256, sha512: add 'auto', and a way to specify default
        * m4/gl-openssl.m4 (gl_CRYPTO_CHECK):
        Add support for a new option, --with-openssl=auto, which causes
        the library to be used if available and silently ignored if not.
        Add support to allow allow configure.ac to specify its own
        default, by setting with_openssl_default before invoking gl_INIT.

2013-12-05  Paul Eggert  <eggert@cs.ucla.edu>

        open-tests: port to glibc with _FORTIFY_SOURCE and -O1
        Problem reported by Daiki Ueno in:
        http://lists.gnu.org/archive/html/bug-gnulib/2013-06/msg00052.html
        * tests/test-open.h (__always_inline):
        New macro, if not already defined.
        (test_open): Use it.

2013-12-04  Eric Blake  <eblake@redhat.com>

        include_next: minimize code duplication
        * modules/include_next (Depends-on): Add absolute-header.
        * m4/include_next.m4 (gl_NEXT_HEADERS_INTERNAL): Reuse
        gl_ABSOLUTE_HEADER_ONE instead of open-coding it.

2013-12-04  Pádraig Brady <P@draigBrady.com>

        getcwd: fix compile error in configure check
        * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): Include errno.h

2013-12-04  Pádraig Brady <P@draigBrady.com>

        regex: suppress core dumps from detection code
        * m4/regex.m4 (gl_REGEX): Catch the SIGABRT and convert to SIGTERM
        to suppress core dumps that may well occur on glibc systems.
        These core dumps might not be cleaned up automatically, or could
        trigger some system core dump handling logic.

2013-12-03  Pádraig Brady <P@draigBrady.com>

        md5, sha1, sha256, sha512: support mandating use of openssl
        * m4/gl-openssl.m4 (gl_crypto_check): Adjust the --with-openssl
        description, to list the now 3 separate options.  also don't
        mention the default=no, since this is implicit given the option
        is described as --with-openssl rather than --without-openssl.
        If projects change the default they're free to document that.
        with --with-openssl[=yes] we now error out when the specified
        hash algorithm is not available in libcrypto.

2013-12-03  Ivailo  <xakepa10@gmail.com>

        test-xvasprintf: (trivial) fix to disable some -Wformat-security diags
        * tests/test-xvasprintf.c: Disable -Wformat-zero-length and
        -Wformat-nonliteral checks, as these edge cases are part of the test.

2013-12-03  Eric Blake  <eblake@redhat.com>

        regex: avoid glibc deadlock during configure
        * m4/regex.m4 (gl_REGEX): Avoid recursive malloc deadlock when
        glibc bug 15078 in turn triggers bug 16159.
        Reported by Michal Privoznik.

2013-12-02  Pádraig Brady <P@draigBrady.com>

        md5, sha1, sha256, sha512: use openssl routines if available.
        --with-openssl the libcrypto md5, sha1, sha224, sha256, sha384, sha256
        routines will be used if available, requiring apps to link @LIB_CRYPTO@
        * lib/gl_openssl.h: Provide wrappers for specified openssl hash.
        * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): New function to lookup libcrypto

2013-11-29  RV1971  <rv1971@web.de>

        base64: (trivial) fix compilation regression on some compilers
        * lib/base64.c: Don't return the void function,
        instead split to a separate return statement.

2013-11-28  Paul Eggert  <eggert@cs.ucla.edu>

        ignore-value: revert previous code change
        * lib/ignore-value.h (ignore_value): Use __extension__ and
        __typeof__ only for GCC 3.4 and later.  Reported by Eric Blake in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-11/msg00102.html>.
        Change the comment to try to explain this better.

2013-11-27  Pádraig Brady <P@draigBrady.com>

        selinux-h: improve stub types and add more stub functions

        * lib/se-selinux.in.h: Change security_context_t to a typedef
        rather than a define, as it's a pointer type and so is better
        as a typedef to avoid issues declaring multiple variables
        with the comma operator.  Also add stub for string_to_security_class().
        * lib/se-context.in.h: Add stub functions for
        context_{type,range,role,user}_get().

2013-11-27  Paul Eggert  <eggert@cs.ucla.edu>

        ignore-value: prefer GCC version back through 2.0
        The code didn't match the comments, so I did a bit of software
        archaeology.  GCC 2.0 seems to support __extension__ and
        __typeof__, so fix both code and comments to use 2.0.
        * lib/ignore-value.h (ignore_value): Use __extension__ and
        __typeof__ for GCC 2.0 through 3.3, too.

2013-11-25  Mats Erik Andersson  <gnu@gisladisker.se>

        pty: Activate the signature wrapper of forkpty.
        The intended preprocessor macro HAVE_FORKPTY is
        never defined, yet `lib/forkpty.c' depends on it.

        * m4/pty.m4 (gl_FUNC_FORKPTY): At completed analysis,
        apply AC_DEFINE_UNQUOTED to HAVE_FORKPTY with value
        $HAVE_FORKPTY for access to wrapper in `lib/forkpty.c'.

        and Paul Eggert  <eggert@cs.ucla.edu>

        quotearg: don't attempt to store 1 << 31 into an "int"
        * lib/quotearg.c (quotearg_buffer_restyled): Building coreutils with
        gcc's new -fsanitize=undefined and running its tests triggered some
        new test failures due to undefined behavior, all with this diagnostic:
          lib/quotearg.c:629:62: runtime error: left shift of 1 by 31 places \
            cannot be represented in type int
        Rather than shifting "1" left to form a mask, shift the bits right and
        simply use "1" as the mask.

        * lib/getgroups.c (posix_getgroups, getgroups) [__APPLE__]:
        New function and macro, to work around _DARWIN_C_SOURCE problem.
        Reported by Jack Howarth in <http://bugs.gnu.org/14463>.

2013-11-11  Pádraig Brady <P@draigBrady.com>

        base64: provide a fast path for encoding well sized buffers
        Avoid conditionals in the base64 encoding loop,
        which was seen to give 60% better throughput.
        * lib/base64.c (base64_encode_fast): A new function to be called
        when we don't want to NUL terminate, and we have enough space
        in the output to encode the given input.
        (base64_encode): Call the _fast() version when appropriate.
        Also remove a redundant mask with 0x3F on the first encoded byte.

2013-11-08  Paul Eggert  <eggert@cs.ucla.edu>

        extern-inline: port better to OS X 10.9
        * m4/extern-inline.m4: Omit serial number; this file doesn't use them.
        (gl_EXTERN_INLINE): Do not suppress the use of extern inline on
        OS X 10.9, except for g++ where the bug is still present.
        See <http://trac.macports.org/ticket/41033>.

2013-11-08  Eric Blake  <eblake@redhat.com>

        fpending: fix regression on DragonFly BSD
        * m4/fpending.m4 (gl_FUNC_FPENDING): Check for declaration.

2013-11-03  Paul Eggert  <eggert@cs.ucla.edu>

        intprops: port to Oracle Studio c99
        * lib/intprops.h (_GL_HAVE___TYPEOF__) [__SUNPRO_C && __STDC__]:
        Define to 0, to avoid diagnostics when Oracle Studio is pedantic.

2013-10-31  Paul Eggert  <eggert@cs.ucla.edu>

        obstack: pacify HP C
        * lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid
        warning "conversion from pointer to smaller integer" from HP
        C-ANSI-C - cc version B9007AA/B3910B A.06.26.  It's safe to assume
        C89 or later nowadays, so cast to void instead of int.  Privately
        reported by H.Merijn Brand.  Also, change header to match glibc's,
        to make checking against glibc easier.

2013-10-29  Jim Meyering  <meyering@fb.com>

        maint.mk: prefer gpgv2 over gpgv
        * top/maint.mk (gpgv): Use gpgv2 if present, else gpgv.
        (gpg_key_ID): Use $(gpgv), rather than hard-coding "gpgv".
        Reported by Gary Vaughan.

        isnan: port to VAX
        Reported by John Klos for NetBSD-5/VAX in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-10/msg00133.html>.
        * lib/isnan.c (IEEE_FLOATING_POINT): New macro, stolen from Emacs.
        (FUNC): Use it.

2013-10-28  Jim Meyering  <meyering@fb.com>

        gnulib-tool: protect against CDPATH
        * gnulib-tool: Many "cd" built-in functions print a directory name
        to stdout when CDPATH is set, e.g.,
          $ bash -c 'CDPATH=/; cd tmp'
          /tmp
        Unset it, when possible.  Prompted by a comment from Bruce Korb.

        maint.mk: restore functionality removed by recent change...
        Sunday's change, v0.0-8062-g6b24f60, may have appeared correct from
        the context of a shallow-cloned gnulib repository: "git describe"
        would fail in such a directory.  However, that change made it so
        the reported gnulib revision no longer includes the version number
        or a commit count, even when run from a full clone.
        * top/maint.mk (gnulib-version): Use the full "git describe"
        output when possible, e.g., the form above, rather than the
        abbreviated, no-tag, no-commit-count string, and fall back to
        using a 10-byte hash, rather than the default minimal-length
        hash prefix, since while the minimal-length one may be fine today,
        it is likely not to be unique for very long.

2013-10-26  Jim Meyering  <meyering@fb.com>

        maint.mk: fix "release" target to build _version
        This fixes a bug in README-release whereby following the outlined
        steps, one would publish a tarball whose programs would report
        --version output not consistent with the package version number.
        This bug caused grep-2.15 to produce a grep program whose
        --version option made it print 2.14.56-1e3d rather than 2.15.
        * top/maint.mk (release): Making this target build "_version"
        ensures that the new version number is reflected in configure.

2013-10-21  Ben Pfaff  <blp@cs.stanford.edu>

        install-reloc: Support multi-binary installation.
        * build-aux/install-reloc: Support installing multiple programs in

        4295fe33eb23f (Multi-file install for PROGRAMS.).  From Bruno
        Haible <bruno@clisp.org>, archived at

        mgetgroups: remove dependency on realloc-gnu
        The dependency violates the comment in realloc-gnu, which
        says that tests can't depend on realloc-gnu; some tests depend
        on mgetgroups, so mgetgroups can't depend on realloc-gnu.

        <http://lists.gnu.org/archive/html/bug-gnulib/2013-10/msg00023.html>.
        * lib/inttypes.in.h (strtoumax): Replace strtoumax if
        REPLACE_STRTOUMAX, thus treating it consistently with strtoimax.
        * m4/inttypes.m4 (gl_INTTYPES_H_DEFAULTS): Add default for
        REPLACE_STRTOUMAX.
        * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX):

        count-leading-zeros: port to MSC; support types wider than 64 bits
        The ideas behind the MSC port are stolen from Emacs.
        * lib/count-leading-zeros.h:
        Don't include verify.h: it's no longer needed, as types wider than
        64 bits are now supported.
        (COUNT_LEADING_ZEROS): New arg MSC_BUILTIN, for better
        performance with MSC.  All uses changed.  Do not assume that TYPE

        performance with MSC.  All uses changed.  Do not assume that TYPE
        has at most 64 bits.
        * modules/count-one-bits (Depends-on): Do not depend on 'verify'.

        pmccabe2html: escaping of special characters
        Escape all '<', '>', and '&' in HTML output.
        * build-aux/pmccabe2html (html_fnc): Call gsub()
        instead of sub() to capture all '<', '>', and '&'.
        Neither of '<' and '>' is special in a regexp,
        so first arguments to gsub() are corrected. Also,
        in replacement strings, ampersand must be escaped.
        Finally, '&' must be handled first, then '<' and '>'.

        <http://lists.gnu.org/archive/html/bug-gnulib/2013-08/msg00028.html>.
        * lib/fpending.h: Don't worry about HAVE_DECL___FPENDING;
        just declare __fpending unless it's a macro.
        A duplicate decl shouldn't hurt.
        * m4/fpending.m4 (gl_FUNC_FPENDING): Check that an __fpending
        call compiles and links, instead of separately checking for
        decl and lib function.
        * modules/fpending (configure-ac):
        Adjust to fpending.m4's renaming of shell variable.

        sys_time: port to OpenBSD
        * lib/sys_time.in.h: Simply delegate to the system's header
        in the BSDish cases as well.  Problem reported by Mike Miller in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-08/msg00016.html>.
        * tests/test-sys_select.c, tests/test-sys_time.c (verify_tv_sec_type):
        Allow platforms like 64-bit OpenBSD where timeval's tv_sec is
        wider than time_t.

        bootstrap: support checksum utils having -c but not --status
        * build-aux/bootstrap: Only look for sha1sum if updating po files.
        Add sha1 to the list of supported checksum utils since it's now
        supported through adjustments below.
        (update_po_files): Remove the use of --status
        in a way that will suppress all error messages, but since this is
        only used to minimize updates, it shouldn't cause an issue.
        Exit early if there is a problem updating the po file checksums.
        (find_tool): Remove the check for --version support as this
        is optional as per commit 86186b17.  Don't even check for the
        presence of the command as if that is needed, it's supported
        through configuring prerequisites in bootstrap.conf.
        Prompt that when a tool isn't found, one can define an environment
        variable to add to the hardcoded search list.

        regex: port to non-glibc/lock-using systems
        Since 29-05-2013 commit, 55ba71f4, compilation on a non-glibc
        system with GNULIB_LOCK would fail due to absence of the
        included "glthread/lock.h".  This would affect any package
        for which the "lock" module is used only by the regex module,
        and not explicitly used.
        * m4/regex.m4 (gl_PREREQ_REGEX): Require gl_GLIBC21.
        * modules/regex (Depends-on) [!GLIBC && $ac_use_included_regex]:
        Add a dependency on the "lock" module.

2013-07-20  Daiki Ueno  <ueno@gnu.org>

        gettext: update to version 0.18.3
        * m4/intl.m4, m4/po.m4: Update from gettext-0.18.3.  In particular,
        require AC_PROG_SED to allow user to specify custom sed command when
        generating en@quot PO file.

2013-07-18  Werner Lemberg <wl@gnu.org>  (tiny change)

        bootstrap: use correct source when copying build-aux files
        * build-aux/bootstrap (gnulib_extra_files): This variable is

        tmpdir: port to VMS, to // != /, and to long dirs
        * lib/tmpdir.c (__libc_secure_getenv) [!_LIBC]: Rename from
        __secure_getenv, so that we're more like the glibc version.
        All uses changed.
        (path_search): Don't put slash after directory if __VMS.
        Problem reported by Steven M. Schweda in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-07/msg00019.html>.
        Simplify code to add slash; no need for a loop.
        Do not remove trailing slash from "//".
        Do not assume dlen <= INT_MAX.

        <http://lists.gnu.org/archive/html/bug-gnulib/2013-07/msg00015.html>.

        accept4, dup3, pipe2: port to Cygwin
        Problem reported for Emacs by Ken Brown in <http://bugs.gnu.org/14821>.

        Problem reported by Charlie Brown in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-07/msg00009.html>.

        pipe2: decouple from binary-io a bit
        This is for Emacs, which needs pipe2 but not binary-io.
        * lib/pipe2.c [!GNULIB_BINARY_IO]: Don't include binary-io.h.
        * modules/binary-io (Depends-on): Add module indicator.

        doc: chatter less
        * doc/Makefile (NEWEST_GNULIB_TEXI_FILE): New macro.
        (updated-stamp): Use it.  This causes 'make' to output just
        one file name rather than zillions.

        fflush, fseeko: port to musl cross-compiles
        * lib/fseeko.c (fseeko): Assume that fflushing stdin works if
        on some implementation that (1) is not known to be buggy,
        (2) claims conformance to POSIX.1-2008 or later, and (3) is being
        cross-compiled to so we can't easily check for lack of
        conformance.  This is for cross-compiling to musl.
        Reported by Rich Felker in

        tests/nap.h: use an adaptive delay to avoid ctime update issues
        The recent change in nap.h (5191133e) decreased the probability of lost
        races to about a third, however such problems could still be observed
        in virtual machines and openSUSE's OBS.
        Before, nap() detected the needed time once empirically and then used
        that delay (together with a small correction multiplier) in further
        calls.  This problem has been reported and discussed several times,
        including guesses about possible kernel issues:
        https://lists.gnu.org/archive/html/bug-gnulib/2013-04/msg00071.html
        http://lists.gnu.org/archive/html/coreutils/2012-03/msg00088.html
        https://lists.gnu.org/archive/html/bug-gnulib/2011-11/msg00226.html
        http://bugs.gnu.org/12820
        https://lists.gnu.org/archive/html/bug-gnulib/2010-11/msg00113.html
        https://lists.gnu.org/archive/html/bug-gnulib/2009-11/msg00007.html
        Now, nap() avoids the race alltogether by verifying on a reference
        file whether a timestamp difference has happened.
        * tests/nap.h (nap_fd): Define file descriptor variable for the
        witness file.
        (nap_works): Change return value to bool.  Change passing
        the old file's status by value instead of by reference as this function
        does no longer update that timestamp; rename the function argument from
        st to old_st.  Remove the local variables cdiff and mdiff because that
        function now returns true/false instead of the precise delay.
        (guess_delay): Remove function.
        (clear_tmp_file): Add new function to close and unlink the witness file.
        (nap): Instead of re-using the delay which has been calculated during
        the first call, avoid the race by actually verifying that a timestamp
        difference can be observed on the current file system.  Use an adaptive
        approach for the delay to minimize execution time.  Assert that the
        maximum delay is <= ~2 seconds, more precisely sum(2^n) from 0 to 30
        = 2^31 - 1 = 2.1s.
        Use atexit to call clear_tmp_file when the process terminates.

        pre-C11 GCC.

        regex: adapt to locking regime instead of depending on pthread

        (lock_lock, lock_unlock): New macros.
        * lib/regexec.c (regexec, re_search_stub): Use the new macros.

        malloca: port to compilers that reject size-zero arrays
        This fixes a bug introduced in my previous patch.

        rather than a character array of size int; that's simpler.
        (struct header): Remove, replacing with ...
        (union header): New type.  This avoids the need for declaring a

        parse-datetime, tests: don't use "string" + int
        Recent versions of 'clang' complain about C source code that
        uses expressions of the form '"string literal" + integer',

        When working around bug 11959, use __REDIRECT rather than '#define
        fwrite(...) ... fwrite (...) ...'.  This is a more-targeted way to
        fix the -Wunused-value issue with clang, and it works with GCC too.
        Problem with targeting reported by Eric Blake in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00067.html>.
        (fwrite_unlocked): Treat like fwrite.  I ran into this issue while
        debugging the fwrite issue.

        stdio: port --enable-gcc-warnings to clang
        * lib/stdio.in.h (fwrite) [__clang__]: Ignore -Wunused-value entirely,
        since the GCC workaround for fwrite does not pacify clang.

        sig2str: port --enable-gcc-warnings to clang
        * lib/sig2str.c (sig2str): Avoid warning about unused printf argument.

        obstack: port --enable-gcc-warnings to clang
        * lib/obstack.h (obstack_ptr_grow_fast, obstack_int_grow_fast):
        Avoid casts from looser to stricter-aligned pointers.

        memchr2: port --enable-gcc-warnings to clang
        * lib/memchr2.c (memchr2):
        Avoid casts from looser to stricter-aligned pointers.

        mbsstr: port --enable-gcc-warnings to clang
        * lib/mbsstr.c (knuth_morris_pratt_multibyte):
        Avoid casts from looser to stricter-aligned pointers.

        malloca: port --enable-gcc-warnings to clang
        * lib/malloca.c (struct header): New member 'magic', to avoid casts.
        (mmalloca): Avoid casts from looser to stricter-aligned pointers.

        inttostr: port --enable-gcc-warnings to clang
        * lib/anytostr.c [__clang__]: Ignore -Wtautological-compare.

        warnings: port to clang
        Problem reported by Daniel P. Berrange via Eric Blake in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00055.html>.

        quotearg: do not read beyond end of buffer
        * lib/quotearg.c (quotearg_buffer_restyled): Do not read beyond the
        end of an ARG for which no length was specified.  With an N-byte
        quote string, (e.g., N is 3 in the fr_FR.UTF-8 locale), this function
        would read N-2 bytes beyond ARG's trailing NUL.  This was triggered
        via coreutils' misc/sort-debug-keys.sh test and detected by running
        the test against a binary compiled with gcc-4.8.0's -fsanitize=address.
        * tests/test-quotearg-simple.c (main): Add a test to trigger the bug.
        * modules/quotearg-simple-tests (Files): Add tests/zerosize-ptr.h.
        Introduced via the 2000-01-15 commit, c4b7f3f8, "Quote multibyte
        characters correctly."

        Assume gnulib is checked out from Git, not CVS

        In fact, access to the gnulib repository through CVS has been
        disabled, or more precisely, got broken and was never restored; see:
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00008.html>

        Note that support for CVS is not removed completely and unthinkingly
        by this change: only support for CVS checkouts of gnulib itself is
        removed.  For example, the 'bootstrap' script still cater to .cvsingore
        files and CVS directories, for the benefit of those poor gnulib clients
        still stuck with CVS.  Ditto for the 'gnulib-tool' script itself.

        * posix-modules: Likewise.
        * MODULES.html.sh: Likewise.

        * NEWS: Update.
        * m4/extensions.m4: While at it, remove a comment mistakenly referring
        to "CVS Autoconf" rather than "git Autoconf".

        unistd: don't prevent Tru64 Unix from using gnulib strtod.
        * lib/unistd.in.h: be careful not to include un-needed system
        stdlib.h from here, because that prevents gnulib stdlib.h from
        defining rpl_strtod correctly.

        regex: rename remaining __attribute calls to __attribute__.
        2012-02-25 changed definition of __attribute, but left some uses

        putenv: port better to native Windows

        Define WIN32_LEAN_AND_MEAN and include <windows.h>.
        (_unsetenv): Use _putenv if available.
        (putenv): Temporarily set NAME=' ' rather than NAME='x' as that's
        a bit less likely to cause damage.
        (putenv) [(_WIN32 || __WIN32__) && ! __CYGWIN__]:

        getcwd: support coreutils better
        Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD,
        but this might not be correct in coreutils, which disables
        the raw decl checks.  Problem reported by Nagendra in
        <http://bugs.gnu.org/10305#192>.
        * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD.
        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX):
        Test the getcwd function, not any macro, since getcwd.c wants the
        function.
        * m4/getcwd.m4 (gl_FUNC_GETCWD):
        Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't
        compile, as might happen if there's a macro but no function.

        strtod: support coreutils better
        * lib/strtod.c (underlying_strtod): Just invoke the underlying strtod.
        HAVE_RAW_DECL_STRTOD might not be correct in coreutils, which
        disables the raw decl checks.  This assumes there is an underlying
        strtod, but that's a safe assumption these days.
        (HAVE_RAW_DECL_STRTOD): Remove; no longer used.

        Reported by Richard Lloyd in
        <http://lists.gnu.org/archive/html/bug-texinfo/2013-02/msg00030.html>.
        * m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE):
        Suppress extern inline with HP-UX cc.  This should be safe,
        though it may hurt performance.  Perhaps someone with some HP-UX
        experience can come up with a higher-performance fix.

        putenv: fix heap corruption with mixed putenv/_putenv
        Problem reported by Michael Goffioul in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00061.html>.
        * lib/putenv.c (putenv) [HAVE__PUTENV]:
        Rely on _putenv to allocate the new environment.
        * m4/putenv.m4 (gl_PREREQ_PUTENV): New macro.
        * modules/putenv (configure.ac): Use it.

        unsetenv etc.: port to Solaris 11 + GNU Emacs
        * lib/canonicalize-lgpl.c, lib/getaddrinfo.c, lib/getdelim.c:
        * lib/glob.c, lib/random_r.c, lib/setenv.c, lib/tsearch.c:
        * lib/unsetenv.c (_GL_ARG_NONNULL): Define before including <config.h>.
        GNU Emacs's <config.h> includes <stdlib.h> (which is not a great
        idea but is too painful to fix right now), and without this gnulib
        change <stdlib.h> was defining _GL_ARG_NONNULL incorrectly when
        compiling unsetenv.c on Solaris 11.  Fix the problem for
        unsetenv.c, and fix other similar occurrences.

2013-02-08  Paul Eggert  <eggert@cs.ucla.edu>

        careadlinkat: stop exporting careadlinkatcwd
        Only Emacs used it directly, and Emacs no longer needs it.
        * NEWS: Document this simplification.
        * lib/areadlink.c (careadlinkatcwd): Move here from careadlinkat.c,
        and make it static.  Include <stdlib.h>, for abort, and unistd.h,
        for readlink.
        * lib/careadlinkat.c (careadlinkatcwd): Move to areadlink.c.
        Don't include stdlib.h; no longer needed.
        * lib/careadlinkat.h (careadlinkatcwd): Remove decl.
        * lib/relocwrapper.c: Adjust comment to match new dependencies.
        * modules/areadlink (Depends-on): Add readlink.
        (Maintainer): Add self.
        * modules/careadlinkat (Depends-on): Remove readlink.

        extensions: port better to HP-UX
        This is merged from git Autoconf.
        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS):
        On hosts that need _XOPEN_SOURCE, define it when configuring, too,
        so that it's compatible with the value used when compiling.

        openpty: fix bug where HAVE_OPENPTY is mistakenly 1
        Problem reported by Mats Erik Andersson in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00051.html>.
        * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the
        openpty function exists, not merely when we intend to replace it.
        This corrects the 2013-01-31 patch, which mistakenly defined
        HAVE_OPENPTY even on hosts that lacked it.

2013-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        secure_getenv: fix include typo
        * lib/secure_getenv.c: Include config.h.  Somehow I forgot!

        secure_getenv: port better to FreeBSD and Solaris
        * lib/secure_getenv.c [!HAVE___SECURE_GETENV]:
        Include unistd.h if HAVE_ISSETUGID, otherwise define a dummy issetugid.
        (secure_getenv) [!HAVE___SECURE_GETENV]: Use getenv if not issetugid.
        This works better on BSDish platforms.
        * m4/secure_getenv.m4 (gl_PREREQ_SECURE_GETENV):
        Test for issetugid if __secure_getenv is missing.

        extensions: port better to MINIX 3, HP-UX, autoheader 2.62
        Some of these changes are merged in from git Autoconf.
        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS):
        When deciding whether to define _XOPEN_SOURCE, inspect the
        preprocessor macro __hpux instead of the more-heavyweight
        operation of requiring AC_CANONICAL_HOST.  Define _NETBSD_HOST on
        MINIX, for MINIX 3.  Use USE_SYSTEM_EXTENSIONS, not __EXTENSIONS__,
        as the key for __EXTENSIONS__.

        unistd: avoid namespace pollution on non-glibc systems
        * lib/unistd.in.h: #define __need_getopt before including <getopt.h>.
        This avoids namespace pollution on non-glibc systems, by causing
        gnulib unistd.h to behave more like glibc unistd.h.  I also hope
        that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-02/msg00027.html>.

        as that's now secure_getenv's job.
        * modules/tmpdir (Depends-on): Add secure_getenv.

        tempname: use secure_getenv
        * lib/tempname.c (__secure_getenv) [!_LIBC]:

        so that they can be kept in sync more easily.  Avoid PATH_MAX
        test on the Hurd.  Sync from test-getcwd.c for errno tests after
        mkdir or chdir failure.
        * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from

        regex-tests, regex: fix bug: memset undeclared
        * tests/test-regex.c: Don't include regex.h twice.  Include
        string.h, to declare memset.  Christensen's report also mentioned
        this issue.
        * m4/regex.m4 (gl_REGEX): Keep test program more in sync with
        test-regex.c, to avoid future problems like this.  Remove

        sys_time: port to Solaris 2.6
        There is a circularity problem on Solaris 2.6, where <time.h> includes
        <sys/time.h> for struct timespec.  The include nesting is gnulib
        <time.h>, system <time.h>, gnulib <sys/time.h>, system
        <sys/time.h>, gnulib <sys/types.h>, system <sys/types.h>, gnulib
        <sys/select.h>, gnulib <signal.h>, system <sys/signal.h>, system
        <sys/siginfo.h>; the last, innermost file needs struct
        timestruc_t, which is defined in <sys/time.h>, which has not been
        fully parsed.  Problem reported by Tom G. Christensen in
        <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00113.html>.
        * lib/sys_select.in.h: Treat Solaris 2.6's problem with
        <sys/time.h> and <sys/types.h> like OSF/1's similar problem.
        * lib/sys_time.in.h: Redo to resemble sys_select.in.h, which

2013-01-20  Bernhard Voelker  <mail@bernhard-voelker.de>

        bootstrap: remove the need for a sorted .gitignore file
        * build-aux/bootstrap (insert_sorted_if_absent): Adjust and
        rename to insert_if_absent(), so that we don't need or generate
        a sorted .gitignore file.  We do require a .gitignore with no
        existing duplicate entries and enforce that.
        (sort_patterns): Remove this function as we now use the simpler
        technigue of inserting blacklist entries at the top of the file,
        assuming gnulib won't be inserting !whitelist entries.

2013-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        readlinkat: don't depend on gl_FUNC_OPENAT
        * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Don't require gl_FUNC_OPENAT.
        Perhaps a similar change needs to be made for linkat.m4, mkfifoat.m4,
        renameat.m4, symlinkat.m4; but one thing at a time.

        statat: new module, split out from fstatat
        GNU Emacs needs the POSIX-specified fstatat, but not the
        gnulib-specified statat and lstat.  Split the latter two into a
        new module 'statat'.
        * lib/openat.h: Depend on GNULIB_STATAT, not GNULIB_FSTATAT.
        * lib/openat.h, lib/statat.c (STATAT_INLINE):
        Rename from FSTATAT_INLINE. All uses changed.
        * modules/fstatat (Files): Remove lib/statat.c.
        (gl_MODULE_INDICATOR([fstatat])): Remove.
        (lib_SOURCES): Remove.
        (Maintainer): Add self.
        * modules/statat, modules/statat-tests, tests/test-statat.c: New files.
        * tests/test-fstatat.c (BASE): Don't define if already defined.
        (do_stat, do_lstat) [!TEST_STATAT]: Test fstatat instead.

        Since stdio.in.h no longer uses inline functions, we no longer
        need to compile the extern versions.
        * lib/stdio.c: Remove.

        update-copyright: avoid copyright notice date corruption
        Given a sequence of copyright year numbers in which the final
        one was a two-digit number that happened to be a substring of
        a preceding four-digit year number, we would mistakenly update
        the substring (from two- to four-digit) rather than the two-digit
        number at the end, which, combined with the addition of the current
        4-digit year number would yield two 5-digit year numbers, e.g.,
        here, it would convert the first "99" to "1999, 2013" rather than
        the final one:
          1991, 99
          11999, 20131, 1999
        * build-aux/update-copyright: Tighten a regexp.

        regex: omit needless signed-pointer casts
        * lib/regcomp.c (build_charclass, build_charclass_op):
        Use char *, not unsigned char *, for class name and extra.
        The char values are always nonnegative so there's no need to
        insist on unsigned char * here, and using char * removes the need
        for casts.  Reported by Aharon Robbins in

2012-12-31  Peter Rosin  <peda@lysator.liu.se>  (tiny change)

        git-version-gen: add --fallback option to use if git is not present

        (scriptversion): Update.

        maint.mk: handle missing git with more grace

        * build-aux/po/Makefile.in.in (install-data, install-data-yes)

        argp: port new 'inline' approach to Sun C 5.12 + Solaris 10
        On this platform, we are not optimizing but we are using

        AC_PROG_MKDIR_P: port workaround to pre-2.62 Autoconf
        * m4/gnulib-common.m4 (AC_PROG_MKDIR_P, AC_C_RESTRICT):
        Use m4_ifndef([AC_AUTOCONF_VERSION], ...), not
        m4_if(m4_version_compare(m4_defn([AC_AUTOCONF_VERSION]),[2.62]),[-1],
        ...), as the latter is fatal with older Autoconfs.
        Problem reported and fix suggested by Eric Blake in thread starting at
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-12/msg00097.html>.

        Define only for Autoconf versions before 2.62.
        (AC_C_RESTRICT): Use documented AC_AUTOCONF_VERSION, not
        undocumented m4_PACKAGE_VERSION, for consistency with the
        abovementioned change to AC_PROG_MKDIR_P.  This should suffice
        since we're checking for 2.62 or later, and AC_AUTOCONF_VERSION
        was introduced in 2.62.

        argp: better 'inline'
        Use extern-inline module to declare extern inline functions.
        This avoids some bogus warning diagnostics.  Problem discovered
        when modifying GNU tar to use the manywarnings module.
        * lib/argp.h, lib/argp-xinl.c (ARGP_EI) [!_LIBC]:

        required by Darwin users whose default /usr/bin/perl does not have all
        the libraries required by help2man, and who need to use their MacPorts
        installation of Perl instead.

        as inline functions, and extern inline is not what's wanted here.
        It would simplify these .h files to remove the extern decls entirely,
        although a downside would be less-clear separation between
        specification and implementation.

        Linux kernel 2.6.39 introduced O_PATH (see

        and the _re suffix to inform that it's a regular expression.

2012-10-26  Eric Blake  <eblake@redhat.com>

        maint.mk: let packages tweak sc_po_check pattern
        * top/maint.mk (sc_po_check): Add translation-markers, to allow
        finding files with other translation markers.

        euidaccess: speed up 'configure' on GNU hosts
        * m4/euidaccess.m4 (gl_FUNC_NONREENTRANT_EUIDACCESS):
        Check for setregid here, not in gl_PREREQ_EUIDACCESS, since
        it's needed only in this case.  Use AC_CHECK_DECLS, not
        AC_CHECK_DECLS_ONCE.
        (gl_PREREQ_EUIDACCESS): Do not use AC_CHECK_HEADERS_ONCE libgen.h
        or AC_REQUIRE for AC_FUNC_GETGROUPS.

        * lib/regexec.c (re_search_internal): Fix grammar in comment.

        fchmodat, fchownat, fstatat: port to non-inlining compilers
        Problem reported for FreeBSD 9 by Jim Meyering in
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-10/msg00070.html>.
        * lib/chmodat.c, lib/chownat.c, lib/statat.c:
        New files, which define FCHMODAT_INLINE etc.
        * lib/fchmodat.c (FCHMODAT_INLINE):
        * lib/fchownat.c (FCHOWNAT_INLINE):
        * lib/fstatat.c (FSTATAT_INLINE):
        Remove, as chmodat.c etc. now do this.
        * modules/fchmodat (Files): Add lib/chmodat.c.
        * modules/fchownat (Files): Add lib/chownat.c.
        * modules/fstatat (Files): Add lib/statat.c.

2012-10-15  Jim Meyering  <jim@meyering.net>

        fchmodat.c, fchownat.c: compile-impeding typos
        * lib/fchmodat.c (FCHMODAT_INLINE): Fix typo: s/#include/#define/
        * lib/fchownat.c (FCHOWNAT_INLINE): Likewise.
        Introduced in commit v0.0-7636-gd202279.

2012-10-15  Paul Eggert  <eggert@cs.ucla.edu>

        fcntl-h: support GNU flags like O_IGNORE_CTTY
        * doc/posix-headers/fcntl.texi (fcntl.h): Support O_IGNORE_CTTY,
        O_NOLINK, and O_NOTRANS.  These flags are nonzero on GNU/Hurd
        systems.  Discovered when using fcntl-h with GNU Emacs, which uses
        O_IGNORE_CTTY.  Fix misspelling of F_SETLKW.
        * lib/fcntl.in.h (O_IGNORE_CTTY, O_NOLINK, O_NOTRANS):
        Define to 0 if not already defined.
        * tests/test-fcntl-h.c: Test these new flags.

2012-10-14  Paul Eggert  <eggert@cs.ucla.edu>

        faccessat, etc.: support AT_FDCWD-only use
        * lib/at-func.c: If GNULIB_SUPPORT_ONLY_AT_FDCWD, then support
        this function only if its first argument is AT_FDCWD.
        Emacs wants faccessat for AT_EACCESS but not for any first-arg
        values other than AT_FDCWD, so it doesn't want all the openat
        machinery with fchdir etc.
        * modules/faccessat, modules/fchmodat, modules/fchownat (Files):
        * modules/fstatat, modules/mkdirat, modules/openat (Files):
        * modules/unlinkat (Files):
        Remove lib/openat-priv.h, as at-internal supplies this file.
        Removing this file here allows us to support programs like Emacs
        that avoid at-internal.

        faccessat: speed up 'configure' on mainstream hosts
        * m4/faccessat.m4 (gl_PREREQ_FACCESSAT):
        Use AT_CHECK_FUNCS for 'access', not AC_CHECK_FUNCS_ONCE,
        since it's only on unusual platforms that we need to check for
        'access', and it's better not to slow 'configure' down on all
        platforms.

        faccessat: port to Solaris 10
        * lib/faccessat.c: Include <fcntl.h>, for AT_EACCESS.
        Needed on Solaris 10, which doesn't have AT_EACCESS,
        so we need the Gnulib fcntl.h, which defines it.

2012-10-14  Pádraig Brady  <P@draigBrady.com>
        canonicalize: fix C89 compilation
        * lib/canonicalize.c (canonicalize_filename_mode): Swap order of
        declarations so C89 is supported.  Also remove the comment
        referencing memorty allocation as the suggested feature could
        not be implemented as suggested.
        Reported by Michael Goffioul.

2012-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        group-member: omit unnecessary dependencies
        This is for Emacs, which has its own allocator and where we
        don't want to use xalloc.
        * lib/group-member.c: Include xalloc-oversized.h, not xalloc.h,
        since we no longer use xmalloc.  Do not include stdbool.h, since
        the changes below happen to remove the only use of bool.
        (GROUPBUF_SIZE): New constant.
        (struct group_info): Remove n_groups member.  Add groupbuf member.
        This lets us get the groups without using malloc, usually.
        (free_group_info, get_group_info): Adjust to this.
        (get_group_info): Return the number of groups found, or -1 on error.
        Use plain malloc not xmalloc, and treat its failure as if there
        are no groups, as the user already loses in case of error.
        (group_member): Simplify, based on changes to get_group_info.
        * modules/group-member (Depends-on): Remove dependencies on
        xalloc and stdbool.  Add dependency on xalloc-oversized.

2012-10-08  Alexandre Duret-Lutz  <adl@lrde.epita.fr>  (tiny change)

        gethrxtime: port to C++

        ptsname: fix macro-name typo

2012-10-03  Simon Josefsson  <simon@josefsson.org>

        inttostr: Relax license.
        * modules/inttostr (License): Change from LGPL to LGPLv2+.

2012-10-03  Eric Blake  <eblake@redhat.com>

        ptsname_r: support ptys returned by FreeBSD posix_openpt
        * lib/ptsname_r.c (__ptsname_r): Don't munge name if it already

        select: enhance test
        * tests/test-select.h (do_select_bad_nfd_nowait, test_bad_nfd):
        New functions.
        (test_function): Enhance test.
        (do_select_bad_fd): Avoid any stale errno values.

        ptsname: reject invalid file descriptors
        http://www.austingroupbugs.net/view.php?id=503
        * m4/ptsname.m4 (gl_FUNC_PTSNAME): Probe for FreeBSD bug.
        * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Add new witness.
        * modules/stdlib (Makefile.am): Replace witness.
        * lib/stdlib.in.h (ptsname): Allow for replacement.
        * modules/ptsname (configure.ac): Trigger replacement.

2012-10-02:  Nikos Mavrogiannopoulos  <nmav@gnutls.org>  (tiny change)

        hash-pjw-bare: new module
        * lib/hash-pjw-bare.c: New file, very much like hash-pjw.c.
        * lib/hash-pjw-bare.h: Likewise.
        * modules/hash-pjw-bare: New file.
        * MODULES.html.sh (Misc): Add it.

2012-10-02  Eric Blake  <eblake@redhat.com>

        manywarnings: cater to more gcc infelicities
        * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add test for

2012-10-01  Ed Maste  <emaste@freebsd.org>  (tiny change)

        select, poll tests: Make setsockopt invocation effective.
        * tests/test-poll.c (open_server_socket): Move setsockopt() call before
        the bind() call.
        * tests/test-select.h (open_server_socket): Likewise.

2012-09-30  Paul Eggert  <eggert@cs.ucla.edu>

        sockets, sys_stat: restore AC_C_INLINE
        This undoes the 2012-09-22 patch.
        * m4/sockets.m4 (gl_SOCKETS):
        * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H):
        Restore AC_C_INLINE, since MSVC requires __inline or _inline
        and does not support plain 'inline'.  Reported by Bruno Haible in
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-09/msg00183.html>.

        Mats Erik Andersson reported the resulting OpenBSD compilation failure.

2012-09-28  Akim Demaille  <akim@lrde.epita.fr>

        extern-inline: provide a -Wundef safe config.h
        * m4/extern-inline.m4 (gl_EXTERN_INLINE): Protect
        "#if __GNUC_STDC_INLINE__" with "defined __GNUC_STDC_INLINE__"
        to produce a -Wundef warning free config.h.

2012-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        hash-pjw: relax license to LGPLv2+

        maint.mk: fix strict vs. lazy variable issues with RELEASE
        * top/maint.mk (_equal): New function.
        (member_check): Strip the result to avoid spurious spaces.
        (url_dir_list): Do not use ifeq, which is strict, as it will
        require RELEASE_TYPE to be defined.
        (announcement_Cc_, announcement_mail_headers_): Likewise: instead
        of relying on ifeq, use $(release_type) to dispatch (lazily) onto...
        (announcement_Cc_alpha,announcement_mail_headers_alpha)
        (announcement_Cc_beta,announcement_mail_headers_beta)
        (announcement_Cc_stable,announcement_mail_headers_stable): these.
        (release): Do not depend on $(release-type), as it forces its
        evaluation.  Bounce to it.

2012-09-25  Akim Demaille  <akim@lrde.epita.fr>

        maint.mk: formatting changes

        maint.mk: factor the validation of RELEASE_TYPE
        With help from Jim Meyering.
        http://lists.gnu.org/archive/html/bug-gnulib/2012-09/msg00132.html
        * top/maint.mk (_empty, _sp): Move their definition earlier.
        (member-check, release-type): New.
        Use the latter instead of $(RELEASE_TYPE).
        Remove now useless local checks.

2012-09-20  Akim Demaille  <akim@lrde.epita.fr>

        maint.mk: provide "make upload" to ease uploading
        See
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-08/msg00028.html>.
        Do not depend simply on the current $(VERSION), as there may have been
        new commits since the tarball generation.  Rather, rely on $(RELEASE),
        as "make release-commit" already does.

        For consistency, add "make release RELEASE='X.Y TYPE'" as an alias for
        "make TYPE".

        * top/maint.mk (upload_command, upload, release): New.
        (RELEASE_TYPE): If undefined, default to the second word of $(RELEASE).
        (VERSION): first word of $(RELEASE) is always right.
        (emit_upload_commands): Adjust.
        * top/README-release: Update.

        * lib/pipe-filter-gi.c (filter_init, filter_cleanup)
        (filter_retcode): No real need for inline here.

        * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H):
        Remove AC_C_INLINE.  Here, 'inline' is used only in MSVC
        environments where it's already guaranteed to work, so we needn't
        check for it at 'configure'-time.

        tls-tests: omit unnecessary 'inline'
        * tests/test-tls.c (perhaps_yield): No longer inline.
        Simplicity and portability trump efficiency in test cases.

        * lib/binary-io.h, lib/malloca.h, lib/safe-alloc.c:
        * lib/xalloc-oversized.h, lib/xsize.h:
        Contrast macros to functions in general, not just to inline functions,
        when the commentary does not apply only to inline functions.

        fts: reduce two or more trailing spaces to just one, usually
        * lib/fts.c (fts_open): Upon initialization, if a name ends in two
        or more slashes, trim all but the final one.  But if a name consists
        solely of two slashes, don't modify it.  If it consists solely of
        three or more slashes, strip all but one.

        This is part of the solution to a minor problem with rm:
        it would print a bogus ELOOP diagnostic when failing to remove
        the slash-decorated name of a symlink-to-directory:

            $ mkdir d && ln -s d s && env rm -r s/
            rm: cannot remove 's': Too many levels of symbolic links

        With the change below and a trivial don't-trim-trailing-slashes
        adjustment to remove.c, it does this:

            $ env rm -r s/
            rm: cannot remove 's/': Not a directory

        gnumakefile: better interaction with Automake-NG
        * modules/gnumakefile [Makefile.am]: The makefiles generated by
        Automake-NG always contain a definition of VPATH, even in non-VPATH
        builds (its value being simply '.' in that case).  So, in the
        'clean-GNUmakefile' rule, to determine whether running under a
        VPATH setup, compare '$(srcdir)' to '.' rather than checking whether
        '$(VPATH)' expands to the empty string.

        Use '#include "foo.h"', not '#include <foo.h>', when including
        one's own interface.  This works better when configuring with
        out-of-directory builds, since packages need not add an
        otherwise-unnecessary -I$(topdir_src)/lib to DEFAULT_INCLUDES.

        This is for better support of 'extern inline' a la ISO C99,
        with a portable alternative on compilers that do not support
        C99-style 'extern inline'.  Using 'extern inline' shrinks the size
        of the Emacs executable, when compiled with debugging disabled,
        which is a typical way that Emacs is built while developing.

        Include string.h.
        (pthread_sigmask) [PTHREAD_SIGMASK_INEFFECTIVE]:
        When calling pthread_sigmask (1729, NEW, OLD), specify non-null NEW;
        this avoids a bug on FreeBSD 9, where pthread_sigmask is effective
        but pthread_sigmask (1729, NULL, NULL) returns zero.

        maint.mk: _sc_search_regexp, sc_vulnerable_makefile_CVE-2009-4029: fix
        Bugs in both of those conspired to make the
        sc_vulnerable_makefile_CVE-2009-4029 rule 99% useless.
        _sc_search_regexp's handling of non-empty $in_files would filter
        out any offending file names.  sc_vulnerable_makefile_CVE-2009-4029's
        choice of in_files value meant there would be no match in most
        projects, due to the presence of two or more Makefile.in files.
        * top/maint.mk (_sc_search_regexp) [in_vc_files,in_files]: Clarify.
        Fix a bug in how a non-empty $$in_files was processed:
        (sc_vulnerable_makefile_CVE-2009-4029): Fix erroneous use of in_files:
        in spite of the name, it's a regexp, not a list of file names.

        getloadavg, getopt: fix commentary re configure.in
        Autoconf is deprecating the name 'configure.in', so change it to
        to the new name 'configure.ac' in a couple of places.
        * lib/getloadavg.c: configure.in -> configure.ac, in comment.
        * m4/getopt.m4 (gl_GETOPT_IFELSE, gl_GETOPT_SUBSTITUTE_HEADER)
        (gl_PREREQ_GETOPT): Remove obsolete commentary re Emacs configure.in.
        Emacs has renamed it to configure.ac, and it no longer refers
        to these macros anyway.

        timespec: mark functions with const attributes

        sys_time: allow too-wide tv_sec
        * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct
        timeval even if tv_sec is wider than time_t.  This allows
        OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c,
        as without this patch gnulib replaces struct timeval
        and OpenBSD futimes therefore has a type mismatch.
        * doc/posix-headers/sys_time.texi: Mention this.

        pthread: check for both pthread_create and pthread_join
        * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, but
        alter the check so that it tests for both pthread_create and
        pthread_join.  This should be more portable to hosts like OSF/1 5.1.
        Suggested by Bruno Haible and Richard Yao in

        Fix comment, and improve error message.
        Perform check first, so that NEWS is not modified uselessly.

        do-release-commit-and-tag: fix typo

        pthread: check for pthread_create, not pthread_join
        * m4/pthread.m4 (gl_PTHREAD_CHECK): Check for pthread_create, not
        pthread_join.  On FreeBSD 9, pthread_create is in libpthread but
        pthread_join in libc.  I hope this removes the need for all the
        OSF/1 5.1 pthread_join business.  Reported by Richard Yao in

        Problem reported by Simon Josefsson in
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-06/msg00246.html>.
        * modules/posixtm-tests (Depends-on): Add stdint.

        Now of type int_least64_t, not int64_t, both because that's
        what INT64_C returns and because int_least64_t works even
        on 72-bit hosts.
        (T): Use INT64_C on constants outside the traditional int range,
        to work around compiler bug noted by Simon.

        mktime: fix integer overflow in 'configure'-time test

        * build-aux/gnu-web-doc-update (--builddir): New option.
        Revamp the handling of options.
        Prefer $(...) to `...`.
        Don't pass --tmpdir=. to mktemp, it is useless given that we specify
        the template, and it is GNU mktemp specific.
        Prefer set -e to long series of &&.
        Restore the initial git branch, not "master".
        Properly initialize submodules (don't rely only on bootstrap).
        Do not reconfigure blindly, use config.status.
        * top/README-release: Update instructions for gnu-web-doc-update.

        do-release-commit-and-tag: support VPATH builds
        * build-aux/do-release-commit-and-tag: Prefer $(...) to `...`.
        (noteworthy): Defined earlier to factor its value.
        (noteworthy_stub): New.
        Use it to factor.
        (help_version): Split into...
        (help, version): these.
        Adjust the option processing part.
        Support "--option=value" in addition to "--option value".
        (builddir): New.
        (--builddir): New option.
        * top/README-release: Document this.
        Reword slightly so that the reader cannot understand that he
        has to do these steps before calling do-release-commit-and-tag.

        mktime: sync from glibc
        * config/srclist.txt: Uncomment mktime.c.
        * lib/mktime.c: Sync from glibc master.  This incorporates 3 changes.
        First, indent with tabs, since glibc uses tabs and doesn't want to
        change and we'd rather be identical to glibc.  Also, two small
        coding changes:
        (isdst_differ): Use &&, not &, as && is the usual style.
        (__mktime_internal): Rename local var from abs_diff to approx_abs_diff
        for clarity.

        poll/select: prevent busy-waiting.  SwitchToThread() only gives away
        the rest of the current time slice to another thread in the current
        process. So if the thread that feeds the file decscriptor we're
        polling is not in the current process, we get busy-waiting.
        * lib/poll.c: Use SleepEx(1, TRUE) instead of SwitchToThread().
        Patch from Theodore Leblond.
        * lib/select.c: Split polling out of the loop that sets the output
        fd_sets.  Check for zero result and loop if the wait timeout is
        infinite.

2012-05-21  Simon Josefsson  <simon@josefsson.org>

        bootstrap: suppress stderr chatter
        * build-aux/bootstrap (insert_sorted_if_absent, main program):
        Omit unnecessary chatter to stderr.  The main program chatter
        was there only inadvertantly.

        bootstrap: .gitignore files created by autopoint, libtool
        I ran into this problem when bootstrapping the latest diffutils.
        After './bootstrap', 'git status' reported lots of untracked files
        m4/codeset.m4, m4/gettext.m4, etc.  These files were created by
        autopoint and do not need to be version-controlled.
        * build-aux/bootstrap: Put into .gitignore the files that
        autopoint and libtool create, by keeping track of files that exist
        after but not before these programs are run.
        (version_controlled_file): Move up.  2nd arg is now full file
        name, not base name; this is more convenient.  Put CVS at the end,
        as it's now somewhat deprecated.

        bootstrap: take advantage of POSIX shell features

        The 'bootstrap' script offered by Gnulib script already uses POSIX
        shell features (like $((...)) arithmetic expansions) that are not
        supported by legacy Bourne shells like Solaris 10 /bin/sh.  This
        means that bootstrap must already be run using a proper POSIX shell,
        which will thus provide more features, like ${var#pattern} parameter
        expansion or inversion of a command exit status with '!'.  We can
        thus use these features to improve the clarity and the performances
        of the bootstrap script.

        Suggested by Eric Blake.

        * build-aux/bootstrap: Prefer xpg4 parameter expansions over use
        of sed/expr plus command substitutions, to save some forks.  While
        we are at it, prefer the POSIX $(...) form of command substitution,
        rather than the legacy form `...` (since the former is visually
        clearer and interacts better with quoting), and prefer the idiom:
          "if ! CMD; then ACTION ..."
        over the idiom:
          "if CMD; then :; else ACTION ..."
        which was required by legacy Bourne shells not supporting '!'.

        * lib/fsusage.c [STAT_STATVFS && __linux__ && (__GLIBC__||__UCLIBC__)]:

        checks dynamically whether statvfs is reliable, falling back on
        Linux-style statfs otherwise.
        (statvfs_works): New function, for dynamically testing statvfs.

        * lib/stdint.in.h (gl_int_fast8_t, gl_uint_fast8_t)
        (gl_int_fast16_t, gl_uint_fast16_t)
        (gl_int_fast32_t, gl_uint_fast32_t)
        (INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX)
        (INT_FAST16_MIN, INT_FAST16_MAX, UINT_FAST16_MAX)
        (INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX):
        Be consistent with glibc by default, and with SunOS 5.10 and later
        if __sun is defined.  This lessens the likelihood of clashes if
        code compiled for older hosts is combined with code compiled for
        newer ones.  Problem reported by Niels Möller in
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-05/msg00074.html>.

2012-04-29  Paul Eggert  <eggert@cs.ucla.edu>

        exclude: process exclude and include directives in order
        This restores the pre-2009 behavior, and is part of a fix of a
        grep bug reported by Quentin Arce in
        <http://lists.gnu.org/archive/html/bug-grep/2012-04/msg00056.html>.
        * lib/exclude.c (struct exclude): Remove 'tail' member.
        (new_exclude_segment): Prepend the new segment instead of appending.
        Return void, since that's now more convenient.
        (file_pattern_matches): Renamed from excluded_file_pattern_p.
        (file_name_matches): Renamed from excluded_file_name_p.
        (file_pattern_matches, file_name_matches):
        Return true if the pattern matches, not if it excludes.
        All callers changed.
        (excluded_file_name): Process the list in reverse order;
        since the list is now reversed this restores the pre-2009 behavior.
        (add_exclude): Adjust to new reversed-order list.  Use local var
        rather than macro, for clarity.
        * tests/test-exclude7.sh: Adjust to corrected behavior.

        exclude: handle wildcards with FNM_NOESCAPE and with trailing \
        * lib/exclude.c (unescape_pattern): Don't worry about unescaped [;
        it's not possible here.  Handle the case of \ at end of pattern
        without dumping core.
        (add_exclude): Do not unescape the pattern if FNM_NOESCAPE is used.

        _Noreturn: future-proof non-GNU and non-MSVC compilers
        * build-aux/snippet/_Noreturn.h (_Noreturn):
        * m4/gnulib-common.m4 (gl_COMMON_BODY):
        Do not define _Noreturn if __STDC_VERSION__ indicates this is
        C11 or later.  This is more likely to work with random future C
        compilers that are neither GNUish nor MSVCish.  See Vincent Lefevre in
        <http://lists.gnu.org/archive/html/bug-gnulib/2012-04/msg00195.html>.

        exclude: handle wildcards with FNM_EXTMATCH
        * lib/exclude.c (fnmatch_pattern_has_wildcards): Also treat '+(',
        '+@', '!(' as wildcards, if FNM_EXTMATCH.  Make it clear in a
        comment that "has wildcards" really means "has or may have
        wildcards".  Simplify by avoiding the need to call strcspn.

        gnulib-tool: fix imprecise comments w.r.t. an automake bug

        It's not just Automake versions < 1.9b that creates an empty
        pkgdatadir at installation time if pkgdata_DATA is specified
        to empty; modern automake versions do this as well, at least
        until automake 1.11.4 (not yet released at the moment of writing,
        but soon to appear).  That behaviour was generally considered a
        feature rather than a bug, at least until this discussion:
        <http://lists.gnu.org/archive/html/automake/2012-03/msg00014.html>

        See also automake bugs #10997 and #11030.

        regex: diagnose too-large repeat counts in EREs
        Previously, the code did not diagnose the too-large repeat count
        in EREs like 'b{1000000000}'; instead, it silently treated the ERE
        as if it were 'b\{1000000000}', which is unexpected.
        * lib/regcomp.c (parse_dup_op): Fail with REG_ESIZE if a repeat count
        is too large.  REG_ESIZE is used nowhere else, and the diagnostic
        is a reasonable one for this problem.  Another option would be to
        create a new REG_OVERFLOW error for repeat counts that are too large.
        (fetch_number): Return RE_DUP_MAX + 1, not REG_ERROR, if the repeat
        count is too large, so that the caller can distinguish the two cases.
        * lib/regex.h (_REG_ESIZE): Document that this is now a generic
        "Too large" return code, and that repeat counts are one example of this.

        regex: allow inclusion of <regex.h> before <limits.h>
        Without this patch, portable programs had to include <limits.h> before
        <regex.h> if they wanted a consistent value for RE_DUP_MAX.
        I ran into this problem with a test version of GNU grep on Solaris 8.
        * lib/regex.h: Include <limits.h> if _REGEX_INCLUDE_LIMITS_H.
        This is done conditionally so that this change can be merged
        back to glibc.

        quotearg: the module must now include quote.h

        quote: fuse into quotearg
        This patch is made for the benefit of Bison.
        quote does not leave the choice of the quoting style to the user.
        quoting_style provides poor customizability, yet quoting_options,
        which is very rich, is hidden inside quotearg.c.  So in order to
        allow quote customization, move its implementation to quotearg.c.

        maint: don't specify XZ_OPT=-9ev in dist-related rule
        Using xz's -9 option is warranted only if you have a very large
        tarball (see xz's documentation for the sizes vs. presets), and
        requires 64MiB of memory at decompression time.
        * top/maint.mk (alpha beta stable): Don't specify XZ_OPT=-9ev.
        Automake's default of just "-e" is fine.  Override on a
        per-package basis by setting XZ_OPT e.g., in cfg.mk.

        regex: re_search etc. should return -2 when memory exhausted
        This bug was uncovered when testing 'grep'.  Without the fix,
        re_search and friends return -1 when memory is exhausted, but -1
        means no match, and this causes grep to falsely report no-match
        instead of memory-exhaustion.  See
        <http://sources.redhat.com/bugzilla/show_bug.cgi?id=13762>.
        * lib/regexec.c (re_search_stub): Return -2 (not -1) if there is
        trouble; this can occur if re_search_internal ran out of memory.

        * lib/file-has-acl.c (file_has_acl) [HP-UX, NonStop Kernel]: Read the

            Bruno Haible  <bruno@clisp.org>

        acl: Don't use GETACLCNT and similar ops, since they are unreliable.

         - There were several instances of this pattern:

             for (;;) {
               n = acl (f, GETACLCNT, 0, NULL);
               [ allocate an array A of size N ]
               if (acl (f, GETACL, n, a) == n)
                 break;
             }

           This loop might never terminate if some other process is constantly
           manipulating the file's ACL.  The loop should be rewritten to
           terminate.

         - The acl (... GETACLNT ...) call is merely an optimization; its value
           is merely a hint as to how big to make the array.  A better
           optimization is to avoid the acl (... GETACLNT ...)  call entirely,
           and just guess a reasonably-big size, growing the size and trying
           again if it's not large enough.  This guarantees termination, and
           saves a system call.

        * lib/acl-internal.h: Include <limits.h>.
        (MIN, SIZE_MAX): New macros.
        * lib/file-has-acl.c (file_has_acl) [Solaris]: Read the entries into

        use GETACLCNT.
        * lib/set-mode-acl.c (qset_acl) [Solaris]: Likewise.

2012-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        regex: merge glibc changes

        * lib/regcomp.c (init_dfa): Tighten overflow checks to test
        for IDX_MAX too, since IDX_MAX can be much less than SIZE_MAX.
        (init_word_char): Work even if bitset words are not exactly 32 or
        64 bits wide.  Don't assume there are no padding bits.
        * lib/regex.c [_LIBC]: Do not include <config.h>.
        [!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure
        and -Wtype-limits.
        * lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid
        needless disagreement with glibc.  All uses changed.  Define it to
        1 only if _GNU_SOURCE, to match glibc.
        (_REG_RM_NAME): Remove; no longer needed, since the names in
        question are now all protected by __USE_GNU.
        (_REG_RE_NAME): Remove; replaced by glibc's __REPB_PREFIX.
        (REG_TRANSLATE_TYPE): Remove; replaced by glibc's __RE_TRANSLATE_TYPE.
        * lib/regex_internal.h (MIN): New macro.

        2012-01-03 Ulrich Drepper <drepper@gmail.com>
        * lib/regcomp.c (init_word_char): Optimize regex a bit.

        2011-12-30 Jakub Jelinek <jakub@redhat.com>
        * lib/regex_internal.c (re_string_fetch_byte_case):
        Fix up regcomp/regexec.  The problem is that parse_bracket_symbol
        is miscompiled, and it turns out it is because of an incorrect
        attribute on re_string_fetch_byte_case.  Unlike
        re_string_peek_byte_case, this one is really not pure, it modifies
        memory (increments pstr->cur_idx), and with the pure attribute GCC
        assumed it doesn't and it cached the presumed value of
        regexp->cur_idx in a variable across the
         for (;; ++i)
           {
             if (i >= BRACKET_NAME_BUF_SIZE)
               return REG_EBRACK;

               ch = re_string_fetch_byte (regexp);
             if (re_string_eoi(regexp))
               return REG_EBRACK;
             if (ch == delim && re_string_peek_byte (regexp, 0) == ']')
               break;
             elem->opr.name[i] = ch;
           }

        2011-11-29 Andreas Schwab <schwab@redhat.com>

        * lib/regcomp.c (parse_branch): One more regex memory leak fixed.

        2011-10-11 Ulrich Drepper <drepper@redhat.com>
        * lib/regcomp.c (parse_branch, parse_sub_exp):
        More regex memory leak fixes and tests.
        (parse_sub_exp, parse_bracket_exp):
        Fix memory leak for some invalid regular expressions.

        2011-05-28 Ulrich Drepper <drepper@gmail.com>
        * lib/regex_internal.c, lib/regexec.c:
        Fix unnecessary overallocation due to incomplete character.  When
        incomplete characters are found at the end of a string the code
        ran amok and allocated lots of memory.  Stricter limits are now in
        place.

        2011-05-20 Reuben Thomas <rrt@sc3d.org>
        * lib/regex.h: Update documentation.

        2011-05-16 Aharon Robbins <arnold@skeeve.com>

        2010-05-05 Andreas Schwab <schwab@redhat.com>

        2010-01-22 Ulrich Drepper <drepper@redhat.com>
        * lib/regex_internal.c (re_dfa_add_node): Extend overflow detection.

        2007-08-26 Ulrich Drepper <drepper@redhat.com>
        * lib/regex_internal.h: Prevent some declarations and definitions
        to be seen when used in tests.

        2005-05-06 Ulrich Drepper <drepper@redhat.com>
        * lib/regex_internal.h: Include bits/libc-lock.h or define dummy
        __libc_lock_* macros if not _LIBC.
        (struct re_dfa_t): Add lock.

2012-02-07  Eric Blake  <eblake@redhat.com>

        maint.mk: also prohibit lower-case @var@
        * top/maint.mk (sc_makefile_at_at_check): Enhance check to cover

        * lib/file-has-acl.c (file_has_acl): This function (for some #ifdefs)
        would evoke a new gcc warning.  Given all of the #ifdefs, it is better
        not even to try to add the attribute.  Instead, add a pragma to suppress

        strtoimax: eliminate need for stdint.h, inttypes.h checks
        * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Don't use
        gl_AC_HEADER_STDINT_H or gl_AC_HEADER_INTTYPES_H.  This reduces
        the prerequisites for a recently-introduced strtoimax test.
        I guess this might cause strtoimax to be replaced when not
        strictly necessary on older hosts, but this shouldn't introduce
        any bugs and it should make Emacs 'configure' faster on typical
        modern hosts.  Problem discovered when importing the latest gnulib
        to an Emacs test version.

        Prompted by discussion with Reuben Thomas and Gary V. Vaughan.

        maint.mk: use more readable (yet functionally equivalent) quoting
        It is common to quote a single quote in a single quoted string like
        this:  '...'\''...'.  Unless you know the idiom, that looks like
        gibberish, so prefer to double-quote the string when possible.
        Then you can use a more readable, lone single quote: "...'..."
        * top/maint.mk (sc_cast_of_argument_to_free): Quoting like this
        "don't" is more readable than the equivalent 'don'\''t'.
        (sc_cast_of_x_alloc_return_value): Likewise.
        (sc_cast_of_alloca_return_value): Likewise.
        (sc_makefile_path_separator_check): Similar: use ":" in '...',
        rather than '\'':'\''.

        stdalign: relax _Alignof and tighten _Alignas test
        * m4/stdalign.m4 (gl_STDALIGN_H): Relax the _Alignof test,
        as it was too strict: alignof must divide offsetof, but it need
        not equal offsetof.  Inspired by Joseph S. Myers's comment
        <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52023#c10>.
        Conversely, tighten the _Alignas test a bit, as the resulting
        alignment must be exactly 8.

        test-init.sh: avoid a subshell
        * tests/test-init.sh: Remove protective subshell.
        Suggested by Bernhard Voelker.  While a subshell is normally
        required to protect against older shells (Solaris, FreeBSD) that
        warn about a missing program before performing redirection, the
        shell-selection tests performed by init.sh probably exclude any
        offending shell.

2012-01-07  Paolo Bonzini  <bonzini@gnu.org>

        quotearg: fall back to Unicode single quotes in UTF-8, GB-18030 locales
        Most programs do not have translation catalogs for English and much
        less separate catalogs for British and American English.  Drop the
        suggestion to translators about these two, and provide it
        automatically for Unicode locales.  Like most programs, even those
        using American English, we use single quotation marks.  This conflicts
        with the American typographic convention, but works better when you
        cite the entire error message within double quotes.  It also tries not
        to clash with established practice and with what non-gnulib programs
        will usually do.
        * lib/quotearg.c (gettext_quote): Hard-code U+2018 and U+2019 when
        using an UTF-8 or GB-18030 locale.  The list of other locales with

        (quotearg_buffer_restyled): Adjust instructions to translators.
        * lib/quotearg.h (locale_quoting_style): Do not put an example in the
        text, since this would be wrong when using Unicode.

        Rationale:
        Microsoft renamed the "Win32 API" to "Windows API", as it is available
        on both 32-bit and 64-bit Windows systems.
        But in gnulib, we treat Cygwin like a Unix platform, therefore the main
        line of distinction is between "native Windows" on one side and Unix/
        POSIX systems on the other side. More details in
        <https://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00027.html>.

        test-framework-sh: init.sh: fix "make dist" failure
        When using gnulib-tool's --with-tests option and any module that
        depends on test-framework-sh, "make dist" would fail due to the
        lack of init.sh *in lib/*.  The EXTRA_DIST += init.sh is required
        in the gltests directory, and not in the gllib/ directory.
        One way to work around that is to move the EXTRA_DIST += init.sh
        from the primary module to the -tests one:
        * modules/test-framework-sh-tests (EXTRA_DIST): Add init.sh here, ...

        gitlog-to-changelog: do not clump multi-paragraph entries
        Identical header lines (date,name,email+coauthors) are suppressed,
        thus putting all entries with those same characteristics under
        a single header.  However, when a log entry consists of two or
        more paragraphs, it may not be clear where it starts and ends.
        This change makes it so that such an entry is always separated
        from others by a header line, even when that header would
        otherwise be suppressed.

        bootstrap: remove some now-unneeded code
        This script arose back when gnulib-tool was young.
        Since then, it has seen improvements that render much of this
        script unnecessary.  In particular, it can now make symlinks
        to the files it uses.  Also, I no longer see as much value in
        marking files as read-only via comments.
        If you relied on the symlink-creation feature of the preceding
        version of this script, you can get most of that functionality
        by adding the --symlink option to the definition of
        gnulib_tool_option_extras in your bootstrap.conf file.
        * build-aux/bootstrap (AUTOPOINT, AUTORECONF): Factor out definitions.

        <http://lists.gnu.org/archive/html/bug-gnulib/2011-11/msg00239.html>

        gitlog-to-changelog: support multi-author commits.
        The FSF cares about keeping track of all authors of patches to its
        projects, but Git doesn't provide obvious support for multi-author
        changesets. Consensus seems to be forming around the use of extra
        Signed-off-by inspired lines in the log message formatted as
        `Co-authored-by: A U Thor <email@example.com>' for round-tripping
        multi-author commits between version control systems.
        * gitlog-to-changelog: Extract `Co-authored-by:' lines from the git
        log message and output in standard ChangeLog multi-author format.
        Reported by Peter Rosin <peda@lysator.liu.se>

        * tests/test-exclude5.sh: Exit with test-exclude's error status

        putenv: indent #definition of "environ" to placate cppi
        * lib/putenv.c (environ): Make indentation reflect cpp nesting.

        gitlog-to-changelog: provide a ChangeLog-repair mechanism
        Git logs are often treated as immutable, because editing them
        changes the SHA1 checksums of all descendants.  Thus, errors in
        git logs tend to stay there forever.  However, when we generate
        a ChangeLog file -- typically for distribution -- from that git log,
        we can actually make corrections in the generated file.  The key
        lies in recording in machine-readable/applicable form the desired
        corrections.  See --help for description and an example.
        * build-aux/gitlog-to-changelog (parse_amend_file): New function.
        (usage): Describe it; alphabetize option descriptions.
        (main): Honor the new option, carefully.

        bar=COMPLICATED; foo=` ... sed -e "$bar" ... ` when COMPLICATED
        contains (possibly-quoted) backslashes.  This should avoid
        all-too-common shell bugs if COMPLICATED contains backslashes in
        the "wrong" places.  Reported by David Evans in
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-11/msg00013.html>.
        When 'sed' uses character ranges like A-Z, invoke it in the C locale,
        because we want ASCII ranges.  Is there some reason we don't use
        the C locale everywhere in this script?
        (func_module, top level): Avoid unwanted pathname expansion when
        $repo_url_prefix or $repo_url_suffix_repl contain shell

        (DECLARE_ALIGNED): Remove.
        (TEST_ALIGNMENT): Define to 16 if alignment is supported (more likely
        to catch bug), and to 1 if not (simplifies the rest of the code).
        (CHECK_STATIC): Always declare the alignment test vars; that's simpler.
        (CHECK_AUTO): Remove.
        (CHECK_ALIGNED): Check only the alignment of the static vars,
        since auto var alignment isn't supported by Sun C 5.11.
        (CHECK_TYPES): Remove.  All uses replaced by inline code, so that
        ASSERT failures are easier to diagnose.

        gitlog-to-changelog: fix git-log invocation.
        git-log mishandles date strings before 1970-01-01 UTC, and there is
        no use to specify --since=1970-01-01 by default anyway.

        GNUmakefile: reenable "make syntax-check" for most projects
        Since Friday's commit 05e2d798, "maint.mk: don't maintain a second
        build-aux variable", "syntax-check" would do nothing but succeed with
        the "No version control files detected..." diagnostic (unless you
        happened to override _build-aux via cfg.mk).
        * top/GNUmakefile (_autoreconf, _build-aux): Move default definitions
        to precede inclusion of maint.mk.  Otherwise, these variables would
        be used undefined in any project that does not override the default.

        overridable $(_build-aux) for projects with a non-standard
        build-aux directory location, although without the $(srcdir)
        prefix.  Use that variable consistently instead of introducing a
        second one.  Adjust all call sites.

        fts: close parent dir FD before returning from post-traversal fts_read
        The problem: the fts-using "mkdir -p A/B; rm -rf A" would attempt to
        unlink A, even though an FD open on A remained.  This is suboptimal
        (holding a file descriptor open longer than needed), but otherwise not
        a problem on Unix-like kernels.  However, on Cygwin with certain Novell
        file systems, (see http://cygwin.com/ml/cygwin/2011-10/msg00365.html),
        that represents a real problem: it causes the removal of A to fail
        with e.g., "rm: cannot remove `A': Device or resource busy"

        fts visits each directory twice and keeps a cache (fts_fd_ring) of
        directory file descriptors.  After completing the final, FTS_DP,
        visit of a directory, RESTORE_INITIAL_CWD intended to clear the FD
        cache, but then proceeded to add a new FD to it via the subsequent
        FCHDIR (which calls cwd_advance_fd and i_ring_push).  Before, the
        final file descriptor would be closed only via fts_close's call to
        fd_ring_clear.  Now, it is usually closed earlier, via the final
        FTS_DP-returning fts_read call.
        * lib/fts.c (restore_initial_cwd): New function, converted from
        the macro.  Call fd_ring_clear *after* FCHDIR, not before it.
        Update callers.

        in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739

        getcwd: don't fail in a deep directory on a system without openat
        Before this change, getcwd would fail when called from a directory
        of depth PATH_MAX / 3 or greater.  That was due to the fact that
        the non-openat implementation used "..", "../..", "../../..", etc.
        to access ancestor directories.  With too many, that string would
        be longer than PATH_MAX.
        * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Define also when we are
        using gnulib's openat replacement.
        * m4/openat.m4: Set GNULIB_OPENAT, so getcwd.c knows when
        we're using the replacement function.

        stat: use pathmax.h only if needed
        * lib/stat.c: Include pathmax.h only if REPLACE_FUNC_STAT_DIR.
        This is better for Emacs, which does not have a mingw port and
        therefore can avoid the pathmax module.

        utimens: remove dependency on dup2
        * lib/utimens.c (fdutimens): Don't invoke dup2; it's not needed

        openat: port to AIX 7.1 with large files
        AIX 7.1 does a "#define openat open64at" if large files are in use,
        so we can't simply #undef openat.  Use the orig_openat trick (similar
        to orig_open in lib/open.c) to work around the problem.  Problem

        openat: test for fstatat (..., 0) bug
        Further testing with tar suggests that fstatat (..., 0)
        does not work in general, on AIX 7.1; see
        <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00023.html>.
        So, give up entirely on AIX 7.1's fstatat, and fall back on our
        replacement fstatat (which is what older AIX releases were using
        anyway).
        * lib/fstatat.c (fstatat) [HAVE_FSTATAT]: Do not undef.  The only
        use is now changed to orig_fstatat.  This was probably the right
        thing to do anyway.
        (FSTATAT_AT_FDCWD_0_BROKEN): Remove; no longer used.
        (rpl_fstatat) [FSTATAT_ZERO_FLAG_BROKEN]: Remove.
        (rpl_fstatat): Simplify, assuming !FSTATAT_ZERO_FLAG_BROKEN.
        (AT_FUNC_NAME) [FSTATAT_ZERO_FLAG_BROKEN]: Now rpl_fstatat.
        * m4/openat.m4 (gl_FUNC_FSTATAT): Test for the more-general bug
        and define FSTATAT_ZERO_FLAG_BROKEN, not FSTATAT_AT_FDCWD_0_BROKEN,
        if the bug is found.

        openat: test for fstatat (AT_FDCWD, ..., 0) bug
        This tests for another fstatat bug on AIX 7.1:
        fstatat (AT_FDCWD, ..., 0) does not work.  See
        <http://lists.gnu.org/archive/html/bug-tar/2011-09/msg00015.html>.
        * lib/fstatat.c (FSTATAT_AT_FDCWD_0_BROKEN)
        (LSTAT_FOLLOWS_SLASHED_SYMLINK): Default to 0.
        (rpl_fstatat): Adjust so that it works around either (or both)
        bugs if present.

2011-08-19  Jim Meyering  <meyering@redhat.com>

        fts: do not exhaust memory when processing million-entry directories
        Before this change, traversing (via rm -rf, find, du, etc.) an N-entry
        directory would require about 256*N bytes of memory.  Thus, it was
        easy to construct a directory too large to be processed by any of
        those tools.  With this change, fts' maximum memory utilization is
        now limited to around 30MB.
        * lib/fts.c (FTS_MAX_READDIR_ENTRIES): Define.
        (fts_read): When we've processed the final entry (i.e., when
        ->fts_link is NULL) and fts_dirp is non-NULL, call fts_build
        using the parent entry to read any remaining entries.  Dispatch
        depending on what fts_build returns:
        - NULL+stop, aka failure: stop
        - NULL otherwise: move up in the dir hierarchy
        - non-NULL: handle this new entry
        (fts_build): Declare and use new local, continue_readdir.
        Prepare to be called from fts_read, when the entries
        from a partially-read directory have just been exhausted.
        In that case, we'll skip the opendir and instead use the parent's
        fts_dirp and derive dir_fd from that.
        Finally, in the readdir loop, if we read max_entries entries,
        exit the loop ensuring *not* to call closedir.  This is required
        so that fts_dirp can be reused on a subsequent call.
        Prompted by Ben England's report of memory exhaustion in find
        and rm -rf vs. NFS: https://bugzilla.redhat.com/719749.

        maint: fts: move decl of `dp' down into while loop; split a long line
        * lib/fts.c (fts_build): No semantic change.

        fts: add/use new struct member, fts_dirp
        We are about to use this to manage any directory with
        too many entries to read all of them into memory at once.
        To do that, we'll need to save the DIR* pointer in each
        affected FTSENT struct.
        * lib/fts_.h: Include <dirent.h>.
        (struct FTSENT) [fts_dirp]: New member.
        * lib/fts.c (closedir_and_clear): Define.
        Use it in place of closedir so that we are sure to
        clear the new fts_dirp member when done with it.
        (fts_alloc): Initialize the new member.
        (fts_lfree): Free, if needed.

        maint: fts: give __opendir2 a new parameter and rename
        * lib/fts.c (__opendir2): Give it a new parameter, Pdir_fd, rather
        than surreptitiously using sole caller's "dir_fd".
        (fts_opendir): Rename from __opendir2.

        maint: fts.c: remove __opendir2's now-unused parameter, oflag
        * lib/fts.c (__opendir2): Remove unused parameter, oflag.

        maint: fts.c: correct off-by-one indentation
        * lib/fts.c (fts_build): Correct indentation, change style
        of a couple of block comments, and bracing style.

        maint: fts.c: move __opendir2 #define "up" out of function body
        * lib/fts.c (__opendir2): Move "up".  No semantic change.

        maint: fts.c: remove #if-0'd FTS_WHITEOUT code
        * lib/fts.c: Remove #if-0'd FTS_WHITEOUT code.  It's been #if-0'd
        out for a long time and besides was useful only on BSD systems.

        modules/relocatable-prog also invokes gl_RELOCATABLE_LIBRARY and
        also needs to build relocatable.c.

        getaddrinfo: fix sh typo in gai_strerrorA decl checking
        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Fix typo in the generated
        shell code: it contained a 'break' that was not in a loop.
        Apparently the macro assumed that AC_CHECK_DECLS is implemenented
        via a shell-language loop; this may have been true in old Autoconf
        versions, but it's not true in Autoconf 2.68.  I found this bug

        about the syntax error.

        maint.mk: avoid sc_prohibit_always-defined_macros failure in coreutils
        * top/maint.mk (gl_extract_significant_defines_): Now that
        SA_RESETHAND and SA_RESTART are #defined (albeit conditionally) in
        gnulib/lib/signal.in.h, and now that we recommend to
        define-if-undefined those two symbols in application code,
        we must filter them out of the "significant" list.
        This avoids a "make syntax-check" failure in coreutils.

        long but int64_t is long long, and where we will clash with the
        system intmax_t if we override it.  See
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-07/msg00160.html>.
        (INTMAX_C, UINTMAX_C): For consistency, respect the system's
        INTMAX_C if INTMAX_MAX and INTMAX_C are both defined, and
        similarly for UINTMAX_C.

2011-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        sys_select: define sigset_t more portably
        * lib/sys_select.in.h: Always include <sys/types.h>, since
        we now need sigset_t and mingw defines it there.
        Include <signal.h> before split inclusion guard, to avoid
        mishaps on Solaris, whose <signal.h> eventually includes us.
        * m4/signal_h.m4 (gl_SIGNAL_H): Require gl_CHECK_TYPE_SIGSET_T.
        (gl_CHECK_TYPE_SIGSET_T): New macro, most of the contents of
        which come from ...
        * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Require
        gl_CHECK_TYPE_SIGSET_T.
        (gl_PREREQ_SIGPROCMASK): Now a no-op, since gl_CHECK_TYPE_SIGSET_T

        * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Poison pselect.
        Suggested by Bruno Haible.

        pselect: Use pthread_sigmask, not sigprocmask.
        * lib/pselect.c (pselect): Use pthread_sigmask, as it supports
        multithreaded apps better than sigprocmask does.
        * modules/pselect (Depends-on): Depend on pthread_sigmask, not
        sigprocmask directly.

2011-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/pselect.c (pselect): Use plain name, without "rpl_".
        Don't #undef,  since we don't need any underlying pselect.
        * modules/pselect (configure.ac): Use our pselect.o if !HAVE_PSELECT.
        (Depends-on): Add select.
        (Link): Add $(LIBSOCKET).
        These changes suggested by Bruno Haible.

        pselect: document better

        * lib/signal.in.h (pthread_sigmask): Arrange for replacement.
        This is done only as a macro; I don't know how well that'll
        work for C++.  Move <sys/types.h> include before the include_next,
        to avoid mishap on Solaris.
        * m4/signal_h.m4 (gl_SIGNAL_H, gl_SIGNAL_H_DEFAULTS): Check for it.
        * modules/signal (Makefile.am): Substitute the check's results.
        * modules/pthread_sigmask, m4/pthread_sigmask.m4: New files.

        test-pselect: new module
        * modules/pselect-tests, tests/test-pselect.c: New files.

        If TEST_PSELECT is defined, test pselect instead of testing select.

        * tests/test-sys_select.c (sigset_t): Test for it, too.
        Suggested by Bruno Haible.

2011-07-03  Jim Meyering  <meyering@redhat.com>

        maint.mk: correct omissions in prohibit_argmatch_without_use check
        This rule would mistakenly report that argmatch.h is included without
        use even when both the argmatch and invalid_arg macro were used.
        * top/maint.mk (sc_prohibit_argmatch_without_use): Also detect uses

        xnanosleep: Rewrite to use new dtotimespec module.
        It has the conversion code that used to be in xnanosleep.
        * lib/xnanosleep.c: Do not include limits.h, stdbool.h, stdio.h,
        assert.h, sys/types.h, or intprops.h.  Include timespec.h instead.

        sys_select: don't depend on sys_socket
        This is so that Emacs doesn't have to drag in m4/sockpfaf.m4 etc; see
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-06/msg00358.html>.
        This fix works on GNU and GNU-like platforms, but has not been tested

        nanosleep: fix integer overflow problem
        * lib/nanosleep.c (my_usleep): Don't assume signed integer
        arithmetic wraps around on overflow.

        nanosleep: simplify carrying
        * lib/nanosleep.c (nanosleep): Use the requested tv_nsec for the
        first call to the underyling nanosleep, not for the last one.
        This doesn't fix any bugs, but it simplifies the computation of
        the remaining delay.  Found while auditing integer overflow issues.

        dup2: remove test for existence of fcntl
        * m4/dup2.m4 (gl_FUNC_DUP2): Use "#ifdef FD_CLOEXEC", not
        "#if HAVE_FCNTL", in the configure-time test program.
        This removes the need for the AC_CHECK_FUNCS_ONCE([fcntl]),
        and therefore speeds up "configure" a bit.  Found while
        adding the dup2 module to Emacs.

        of the bug Eric has just fixed, with today's commit 25e4c2ec.

        * lib/alloca.c (find_stack_direction): New signature, taken from
        Autoconf git.  This works with GCC 4.6.0.  This code should never
        be used with GCC 4.6.0 itself, as GCC has alloca, but it might
        be used with other compilers that optimize as well as GCC 4.6.0 does.
        (alloca): Adjust to new signature.

        * lib/c-stack.c (find_stack_direction): Remove.
        (segv_handler): Don't worry about stack direction growth, as it's
        too much of a pain to configure this correctly, given how compilers
        are optimizing-away our stack-growth detection code.  Instead, assume
        that any access to just before or just after the stack is OK.
        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC):
        Don't require AC_FUNC_ALLOCA; no longer needed.

2011-06-20  Eric Blake  <eblake@redhat.com>

        test-stat: don't allocate PATH_MAX bytes

        tests init: new function 'fatal_', for hard errors
        Before this patch, the only way offered by tests/init.sh to
        properly signal a hard error was the `framework_failure_'
        function.  But the error message issued by that function,
        as its name would suggest, refers to a set-up failure in the
        testsuite, while hard errors can obviously also be due to
        other reasons.  The best way to fix this inconsistency is to
        introduce a new function with a more general error message.

        the scope in which "ts" was valid.
        * lib/utimensat.c (rpl_utimensat) [__linux__]: Move the declaration

        maint.mk: prohibit doubled words
        Detect them also when they're separated by a newline.
        There are 3 ways to customize it:
          - disable the test on a per file basis, as usual with rules using
            $(VC_LIST_EXCEPT)
          - replace the default doubled-word-selecting regexp (affects all files)
          - ignore a particular file-vs-doubled-word match
        I nearly used that last one to ignore the "is is" match in
        coreutils' NEWS file, since the text was "ls -is is ..."
        To do that, I would have added this line to cfg.mk:
          ignore_doubled_word_match_RE_ = ^NEWS:[0-9]+:is[ ]is$
        but it would have ignored any "is is" match in NEWS.
        Low probability, but still...
        Instead, I changed the text, slightly:
          -  ls -is is now consistent with ls -lis in ignoring values returned
          +  "ls -is" is now consistent with ls -lis in ignoring values returned
        * top/maint.mk (prohibit_double_word_RE_): Provide default.
        (prohibit_doubled_word_): Define.

        strftime: don't assume a byte count fits in 'int'
        * lib/strftime.c (add): Don't assume first arg fits in 'int'.  I
        found this problem by static analysis, using gcc -Wstrict-overflow
        (GCC 4.5.2, x86-64).  This reported an optimization that depended
        on an integer overflow having undefined behavior, but it turns out
        that the argument is a size, which might not fit in 'int' anyway,

        stdio: don't require ignore_value around fwrite

        This patch works around libc bug 11959
        <http://sources.redhat.com/bugzilla/show_bug.cgi?id=11959>.
        Without this patch, applications must often write
        ignore_value (fwrite (...)) even though the ignore_value is
        not helpful here.  It's common to write many objects, using
        fwrite/printf/etc., and then use ferror to detect output error.

        I considered making this patch optional, but decided against it,
        because libc is obviously being inconsistent here: there is no
        reason libc should insist that user code must inspect fwrite
        return's value without also insisting that it inspect printf's,
        putchar's, etc.  If user code wants to have a strict style where
        all these functions' values are checked (so that ferror need not
        be checked), we could add support for that style in a new gnulib
        module, but in the meantime it's better to be consistent and to
        support common usage.

        * lib/stdio.in.h (rpl_fwrite): Define this wrapper around fwrite,
        to work around libc bug 11959, if __USE_FORTIFY_LEVEL indicates
        that we are compiling in checking mode, and if not C++, and
        if not already wrapping fwrite for some other reason.
        (fwrite): #define to rpl_fwrite if the latter is defined.

        socklen: do not depend on sys_socket
        While trying to modify Emacs to use gnulib's socklen module,
        I discovered a circular dependency: socklen depends on sys_socket
        and vice versa.  Emacs can use socklen, but it does not need
        sys_socket because it has its own substitute for sys/socket.h.
        * m4/socklen.m4 (gl_SOCKET_HEADERS): New macro, extracted from

        maint.mk: allow fine-grained syntax-check exclusion via Make variables
        Before, you would have had to create one .x-sc_ file per rule in order

        usually defined in cfg.mk -- whose name identifies the affected rule.

        dirname: move m4/dos.m4 functionality into lib/dosname.h

        m4/dos.m4 needs to go.  It laboriously invokes the C compiler, and
        extracts symbols from it, puts them into config.h; but it's much
        easier to use the symbols directly.  filename.h already does this,
        but it disagrees with dos.m4 in some respects.  This patch
        introduces a different include file dosname.h that packages up
        dos.m4, and then later we can work on merging filename.h and
        dosname.h.  Applications that need only the easy-to-configure
        symbols should consider including dosname.h rather than dirname.h.
        * NEWS: Mention incompatible changes.
        * m4/dos.m4: Remove.
        * lib/dosname.h, modules/dosname: New files.

        * lib/at-func.c, lib/at-func2.c, lib/openat.c, lib/savewd.c:
        Include dosname.h, not dirname.h.
        * lib/rmdir.c, lib/stat.c, lib/unlink.c, lib/unlinkat.c:
        Include dosname.h, for definitions of symbols like ISSLASH
        that used to be in config.h.
        * m4/dirname.m4 (gl_DIRNAME_LGPL): Do not require gl_AC_DOS.

        use a symbol HAVE_DOS_FILE_NAMES, but that symbol is meant only
        for the rare case of programs that want all their backup file
        names to live within 8+3 limits, and dos.m4 doesn't address that.
        * modules/backupfile (Files): Remove m4/dos.m4.

        longlong: tune, particularly for common case of c99

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Don't bother compiling
        or running anything if c99, or if unsigned long long int does not
        work.  In either case, we know the answer without further tests.
        Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice.  Instead, compile
        it at most once, and use its results for both long long int and
        unsigned long long int.  This is more likely to be efficient in
        the common case where the program wants to check for both long
        long int and unsigned long long int.
        (AC_TYPE_UNSIGNED_LONG_LONG_INT): Don't bother compiling if c99,
        since the answer is already known.

        Omit setgid-related tests that generate symbols KMEM_GROUP,
        NEET_SETGID, GETLOADAVG_PRIVILEGED; nobody seems to use those any more.
        Do only the tests that are needed to see whether the system has
        getloadavg, moving the other tests into ...
        (gl_PREREQ_GETLOADAVG): ... here.  Do not define obsolete symbol
        NLIST_NAME_UNION; nobody should be using it.  Do not define
        symbols C_GETLOADAVG and HAVE_GETLOADAVG; they're no longer
        relevant, as the user of this module shouldn't care how getloadavg
        is implemented.

        stdlib: support non-GCC __attribute__

        Fix a serious and tricky problem encountered when attempting to
        add the getloadavg module to Emacs.  Emacs worked fine on RHEL
        5.5, but it crashed due to memory corruption on Solaris 10 with
        Sun C 5.11.  Emacs normally ORs 3-bit tags into their low-order
        bits that are otherwise zero.  This tagging is optional inside
        Emacs but is preferred and is used when __attribute__ ((__aligned
        (8))) works, as it does with both recent-enough GCC and with Sun C
        5.11.  However, Sun C 5.11 is not GCC and does not #define
        __GNUC__ and __GNUC_MINOR__.

        When I added the getloadavg module to Emacs, it brought in
        stdlib.in.h, which contained this fragment:

           #ifndef __attribute__
           # if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 8)
           #  define __attribute__(Spec)   /* empty */
           # endif
           #endif

        When files that include <stdlib.h> were compiled with Sun C 5.11,
        the above code disabled __attribute__ ((__aligned (8))), which
        caused variables to not be properly aligned, which eventually led
        to the pointer corruption mentioned above.  (This was a bit hard
        to diagnose, unfortunately.)

        Several "#define __attribute__(X) /* empty */" code snippets need
        to be eradicated from Gnulib to work with non-GCC compilers that
        support __attribute__.  The Autoconf way to do this is to test for
        each kind of attribute that we want support for, and selectively
        enable that in source code.

        Fix this problem just for stdlib.h, by adding a test for the
        __noreturn__ attribute, and change stdlib.in.h to use that test
        when needed.  This technique can be easily generalized to the
        other *.in.h files and attributes, and a similar technique can be
        used for *.h and *.c files.  This patch is enough to solve the
        problem for Emacs + getloadavg, and I thought I'd publish it for
        feedback before undertaking further, similar fixes in other
        modules.

        This patch does not arrange to #define HAVE_ATTRIBUTE_NORETURN
        because it's not needed for stdlib.h.  It merely substitutes the
        value directly into stdlib.h.  We may well need to #define it, or
        similar symbols, for other modules, but it's nice to also have an
        option to not #define it for applications like Emacs that do not
        need it.

        * lib/stdlib.in.h (__attribute__): Do not #define.
        (_GL_ATTRIBUTE_NORETURN): New macro, which in stdlib.h needs to

        mktime: fix some integer overflow issues and sidestep the rest

        This was prompted by a bug report by Benjamin Lindner for MinGW
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00472.html>.
        His bug is due to signed integer overflow (0 - INT_MIN), and I
        I scanned through mktime.c looking for other integer overflow
        problems, fixing all the bugs I found.

        Although the C Standard says the resulting code is still not safe
        in the presence of integer overflow, in practice it should be good
        enough for all real-world two's-complement implementations, except
        for debugging environments that deliberately trap on integer
        overflow (e.g., gcc -ftrapv).

        * lib/mktime.c (WRAPV): New macro.
        (SHR): Also check that long_int and time_t shift right in the
        usual way, before using the fast-but-unportable method.
        (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer
        used.  The code already assumed two's complement, so there's
        no need to test for alternatives.  All uses removed.
        (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by
        the C standard.  Problem reported by Rich Felker in
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00488.html>.
        (twos_complement_arithmetic): Also check long_int and time_t.
        (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions.
        (guess_time_tm, ranged_convert, __mktime_internal): Use them.
        (__mktime_internal): Avoid integer overflow with unary subtraction
        in two instances where -1 - X is an adequate replacement for -X,
        since the calculations are approximate.

2011-01-29  Eric Blake  <eblake@redhat.com>

        mktime: avoid infinite loop

        mktime: avoid problems on NetBSD 5 / i386

        on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits
        but time_t is 64 bits, and where I expect the existing code is

        include_next: do not check for standard headers like stddef.h

        I found this problem when modifying Emacs to use gnulib.
        I noticed that it added HAVE_STDDEF_H to config.h, even though

        strftime: remove dependencies on multibyte modules

        strftime depended on mbrlen, mbsinit, and wchar, but these modules
        are needed only if ! MULTIBYTE_IS_FORMAT_SAFE, and that is true
        only if __osf__ is defined, and I suspect OSF doesn't need these
        other modules.  If my guess is wrong, we'll need to come up with a
        variant of strftime that doesn't need the multibyte modules.

        I discovered this problem when attempting modify Emacs to use the
        strftime module.  With the previous gnulib, this caused Emacs to
        need 31 new files, ranging from lib/config.charset to
        m4/wint_t.m4.  This was overkill and I expect would be offputting
        to the Emacs maintainers.  After this change, only 6 new files are
        needed, namely strftime.[ch], srtftime.m4, stdbool.in.h,
        stdbool.m4, and tm_gmtoff.m4.

        * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always.

        save-cwd: no longer include "xgetcwd.h"
        * lib/save-cwd.c: Don't include "xgetcwd.h"; it's no longer used.
        This avoids a compilation failure in projects that use save-cwd
        without also using the xgetcwd module.

        ftoastr: split into 3 modules ftoastr, dtoastr, ldtoastr
        This is so that a program like Emacs, which needs only dtoastr,
        does not have to bother with distributing and compiling ftoastr
        and ldtoastr.
        * MODULES.html.sh: Document these modules (ftoastr wasn't documented).
        * modules/dtoastr, modules/ldtoastr: New files.
        * modules/ftoastr: Now works just for 'float'.
        (Files): Remove lib/dtoastr.c, lib/ldtoastr.c.
        (Makefile.am): Remove ftoastr.h (not needed and no effect),
        dtoastr.c, ldtoastr.c.

        save-cwd: remove #if-!HAVE_FCHDIR'd code; use the fchdir module
        There is no need to work around the lack of the fchdir function,
        since gnulib can now provide a replacement when required.
        * lib/save-cwd.c: Remove #if !HAVE_FCHDIR...#endif code.
        * modules/save-cwd (Depends-on): Add fchdir.

        openat, save-cwd: avoid xmalloc

        This removes a direct (but undocumented) dependency of openat on
        xalloc, along with an indirect dependency via save-cwd.  It also
        removes a dependency of save-cwd on xgetcwd, and thereby
        indirectly on xalloc.  This change causes the openat substitute
        to fall back on save_cwd when memory is tight, and for save_cwd to
        fail instead of dying when memory is tight, but that's good enough.
        Problem and initial idea for fix reported by Bastien Roucaries in
        <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00170.html>.

        * lib/openat-proc.c: Include stdlib.h (for malloc), not
        xalloc.h (for xmalloc).
        (openat_proc_name): Use malloc, not xmalloc.
        * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd.
        * modules/save-cwd (Files): Depend on getcwd, not xgetcwd.

        openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024
        This avoids heap allocation for file names whose lengths are in
        the range 512..1023, with the upper bound increasing to at most
        4031 depending on the platform's PATH_MAX.  (We do not want
        pathmax.h here as it might supply a non-constant PATH_MAX.)
        * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros.
        Perhaps they should be moved to malloca.h?
        (OPENAT_BUFFER_SIZE): Use them.

        useless-if-before-free: fix typo in --help and make the internal,
        automatic version date update process work once again.
        --help output contained a NUL character instead of the
        backslash-zero that was intended.  Also, the "must lie within
        the first 8 lines" line is on line 9, and hence not getting
        automatically updated.
        * build-aux/useless-if-before-free: Fix the former by adding a
        backslash, and the latter by condensing the three lines of what-it-does
        to a single line, leaving one line of slack for the future.

        checksums, suppress the diagnostic and handle the failure.
        Reported by Bruce Korb in http://marc.info/?l=git&m=129399145930450&w=2

        git-version-gen: include command name in one more diagnostic
        * build-aux/git-version-gen: When the required .tarball-version file
        was missing or unreadable, you might see the diagnostic from "cat",
        but no trace of the name of the invoking script.  Now, you still see
        the diagnostic from cat, but also get one from "git-version-gen: ".
        Inspired by a patch from Bruce Korb.

        modified how this file was generated before I initially submitted
        the module, but failed to regenerate it.  This meant that several
        of the level2 entries were wrong.

        * lib/time.in.h (localtime_r, gmtime_r): Test HAVE_DECL_LOCALTIME_R
        instead of HAVE_LOCALTIME_R.
        * m4/time_r.m4 (gl_TIME_R): Test whether localtime_r is declared. Set

2010-12-29  Paul Eggert  <eggert@cs.ucla.edu>

        ftoastr, snprintf: ftoastr + snprintf module
        * lib/ftoastr.c: Use GNULIB_SNPRINTF, not GNULIB_SNPRINTF_POSIX,
        since the snprintf module now should be good enough here.
        * modules/snprintf (configure.ac): Add gl_MODULE_INDICATOR([snprintf]).
        It seems odd to have both gl_STDIO_MODULE_INDICATOR([snprintf])
        and gl_MODULE_INDICATOR([snprintf]), but the former enables
        GNULIB_SNPRINTF only for the test directory, and the latter
        doesn't arrange for gl_STDIO_H_DEFAULTS to be called, so neither
        seems to suffice by itself.

        * lib/alloca.c (find_stack_direction): New arg PTR, to avoid the
        need for a static variable.  All callers changed.  This does not
        make the alloca replacement thread-safe, but it's one step.

        tests: minor indenting change
        * tests/init.sh: Sync from coreutils housekeeping patch
        <http://lists.gnu.org/archive/html/coreutils/2010-12/msg00116.html>
        to keep lines within 80 columns.

        regex: don't infloop on persistent failing calloc
        * lib/regexec.c (build_trtable): Return failure indication upon
        calloc failure.  Otherwise, re_search_internal could infloop on OOM.
        In glibc, this was fixed for version 2.13:

        way, and to -2 if it needs a generic runtime test.
        * lib/linkat.c (solaris_optimized_link_immediate,

        tests: port test-fdutimensat.c to Solaris 8
        * tests/test-fdutimensat.c (do_fdutimens): Don't assume
        fdutimensat works with a nonnegative fd and AT_SYMLINK_NOFOLLOW.
        On Solaris 8, it fails with errno == ENOSYS, because there is no
        futimens (so it can't use the fd), and there is no lutimens (so it
        can't implement AT_SYMLINK_NOFOLLOW on symlinks).

        * doc/posix-functions/vsnprintf.texi (vsnprintf):
        * doc/posix-functions/vsprintf.texi (vsprintf):
        Mention that these functions mishandle large floating point
        precisions on Solaris 10.  The same bug is also present in Solaris
        8, and I assume earlier.  This causes "cd gnulib-tests; make
        check" to fail on Solaris 8 (and I assume, later) when building
        the latest coreutils, in test-vasprintf-posix's call to
        my_asprintf (&result, "%.4000f %d", 1.0, 99).  I have not checked
        the wide flavors (e.g., wprintf) so this patch just updates the
        documentation for the narrow ones.

        test-posixtm.c: add two tests
        * tests/test-posixtm.c: Add two tests, to highlight the

        snprintf: port snprintf (NULL, 0, ...) to Solaris 8 and 9
        This fixes a problem observed with the latest coreutils snapshot
        that caused a test to fail on Solaris 8.  src/csplit.c's call
        snprintf (NULL, 0, format, UINT_MAX) returns -1 on Solaris 9 and
        earlier, instead of returning the number of bytes that would have
        been generated; this causes csplit to incorrectly report memory
        exhaustion.
        * m4/printf.m4 (gl_SNPRINTF_RETVAL_C99): Also check for
        snprintf (NULL, 0, ...) and (for good measure) snprintf (buf, 0, ...).
        Guess that it doesn't work on Solaris 2.6 through 9.  Adjust
        comments to match.
        (gl_PRINTF_SIZES_C99, gl_PRINTF_DIRECTIVE_F, gl_SNPRINTF_RETVAL_C99):
        Fix typo in matching older versions of Solaris: "solaris2.10"
        is matched by the shell pattern "solaris2.[0-9]*".  This matters
        only for guessing while cross-compiling.
        * m4/snprintf.m4 (gl_FUNC_SNPRINTF): Also check gl_SNPRINTF_RETVAL_C99.

        acl: port to Solaris 8 when copying from tmpfs to ufs
        * lib/copy-acl.c (qcopy_acl): Also allow EINVAL as an ignorable
        error number.  Problem observed on Solaris 8 with latest
        coreutils, with "mv A B", where A is on a tmpfs file system and B
        is on a ufs file system.  This caused coreutils' mv/part-symlink
        test to fail.

        tests: set fail=0 at start
        * tests/init.sh (setup_): Move fail=0 initialization here ...
        (mktempd_): ... from here, so that tests can rely on fail being
        set to 0 initially.  This fixes a problem in coreutils; see:

        memmem by using just this module.

        pointer is returned, not just a non NULL pointer.
        * doc/glibc-functions/memmem.texi: Rearrange the portability
        documentation to correlate with the rearranged checks.

        utimecmp: fine-grained src to nearby coarse-grained dest

        * lib/utimecmp.c (utimecmp): When UTIMECMP_TRUNCATE_SOURCE is set,
        and the source is on a file system with higher-resolution time

        determine the exact resolution from the read-back mtime was buggy:
        it had a "!=" where it should have had an "==".  This bug has been
        in the code ever since it was introduced to gnulib.
        Problem reported by Dan Jacobson in

        stdint: port to GCC 4.3 + OSX + Octave
        On this platform, stdint.h is buggy and defines int64_t to long
        long int.  The replacement defined it to long int, causing
        problems with C++ style name mangling.  Instead, trust the system
        definition if INT64_MAX is defined, and likewise for the unsigned
        variant.   Problem reported by Jarno Rajahalme in
        <http://lists.gnu.org/archive/html/bug-gnulib/2010-04/msg00143.html>.
        * lib/stdint.in.h (GL_INT64_T): Define if INT64_MAX is defined,
        and don't mess with int64_t and INT64_MAX in this case.
        (GL_UINT64_T): Likewise for UINT64_MAX and uint64_t.

        (fdopendir_with_dup, fd_clone_opendir): Now have extra CWD arg.

        fdopendir: fix a bug on systems lacking openat and /proc support
        OpenBSD 4.7 is one such system.  The most noticeable effect was
        failure of any application making nontrivial use of fts: rm, du,
        chown, chmod etc.  E.g., "mkdir -p a/b; ./rm -rf a" would fail with
          ./rm: traversal failed: `a': Bad file descriptor
        Debugging that, you see that even though FD 6 was closed just
        prior to the opendir call in fd_clone_opendir, its resulting
        dir->dd_fd was 8, rather than the expected value of 6:

        Breakpoint 3, fdopendir_with_dup (fd=6, older_dupfd=-1) at fdopendir.c:93
        93                close (fd);
        (gdb) n
        94                dir = fd_clone_opendir (dupfd);
        (gdb) n
        95                saved_errno = errno;
        (gdb) p dir->dd_fd
        $11 = 8

        Notice how it closes FD 6, then gets a DIR* pointer using FD 8.
        The problem is that on OpenBSD, fd_clone_opendir has to resort
        to using the old-style save/restore CWD mechanism, due to its
        lack of openat/proc support, and *that* would steal the FD (6)
        that opendir was supposed to use.

        The fix is to squirrel away the desired FD so that save_cwd uses a
        different one, and then free the dest FD right before calling opendir.
        That guarantees opendir will use the required file descriptor.

        * lib/fdopendir.c (fd_clone_opendir): Handle the above.

        so it needs the file names in this file to be relative to the top
        level, not relative to lib; plus it needs variable names to be
        rewritten.

        init.sh: penalize a set-x-impaired shell; don't disqualify it
        * tests/init.sh: Too many shells corrupt application stderr when
        you set -x, so we can't afford to disqualify them, since at least
        on Irix-6.5, that would disqualify all bourne shells.
        Instead, use a two-pass approach.
        On the first pass, try to find a shell that meets the stricter
        condition that set -x does not corrupt stderr.
        If no shell meets the stricter condition, retest each candidate
        shell, but without that extra condition.  Finally, when
        VERBOSE=yes is requested and set -x might cause trouble, simply
        issue a warning and refrain from enabling debug output.

        fcntl-h, etc.: prefer O_SEARCH to O_RDONLY when applicable

        POSIX 2008 specifies a new 'open' flag O_SEARCH, which can be used
        when one needs search access to a directory but not read access.
        On systems where it is available, it works in some cases where
        O_RDONLY does not, namely on directories that are searchable but
        not readable, and which need only to be searchable.  If O_SEARCH
        is not available, fall back to the traditional method of using
        O_RDONLY.

        * lib/fcntl.in.h (O_SEARCH): #define to O_RDONLY if not defined.
        * lib/chdir-long.c (cdb_advance_fd): Use O_SEARCH, not O_RDONLY,

        getcwd: on Solaris, work better if ancestors are inaccessible
        * lib/getcwd.c (__getcwd): If getcwd returns EINVAL for zero
        buffer and size, try again with a large buffer.  This works better
        on Solaris, since its getcwd succeeds even if the path to the root
        is inaccessible, and this is helpful in common cases such as .zfs
        hidden directories.  Problem reported by J Chapman Flack in
        http://lists.gnu.org/archive/html/bug-tar/2010-06/msg00000.html
        Use system getcwd if it's declared, not merely if it's partly
        working; use the partly-working test only to avoid needless effort
        if the system getcwd fails.
        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Omit
        comment that was already obsolete and is now even more obsolete.
        * modules/getcwd (Depends-on): Depend on strdup, since __getcwd
        now might call strdup.

        memcoll: clarify sizes versus lengths, document better, and tweak perf
        * lib/memcoll.c (strcoll_loop, memcoll0):

        (ldexp): Provide an unused dummy if not available.
        (scale_radix_exp, parse_number, underlying_strtod): New functions.
        (strtod): Use them.  This implementation prefers to use the
        underlying strtod if available, falling back on our own code
        only to fix known bugs.  This is more likely to produce an
        accurate result.  Also, it avoids the use of libm functions.
        * m4/strtod.m4 (gl_FUNC_STRTOD): Don't invoke _AC_LIBOBJ_STRTOD;
        no longer needed.  Invoke AC_LIBOBJ([strtod]); don't know why this
        was absent, but it caused a test failure with coreutils.

        differs from memcoll in that the NUL byte is part of the argument.
        Omit the abort-checks, as performance is a real issue here.  Plus,
        the checks were wrong anyway (an off-by-one error).  Omit local
        variable 'diff', as it's a bit clearer that way.
        * m4/memcoll.m4 (gl_MEMCOLL): Omit AC_FUNC_STRCOLL, as it's
        no longer needed.

        bootstrap: fix an error when gnulib is not used as a git submodule
        * build-aux/bootstrap (gnulib_path): If its length is zero then
        assign "gnulib" to it.
        * build-aux/bootstrap: Redirect "git clone -h" stderr to stdout.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        Avoid autoconf warnings about AM_ICONV.
        * m4/iconv.m4 (AM_ICONV): Define using AC_DEFUN_ONCE for autoconf >=
        2.64.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        absolute-header: Make the macro usable in more situations.

2010-05-16  Jim Meyering  <meyering@redhat.com>

        init.sh: fix an error in the previous change; add more comments
        * tests/init.sh: Compare exit code in loop against 9, not 2.
        Patch by Bruno Haible.
        Make the two tests more similar by adding an empty "then" clause.
        Add comments.

        init.sh: avoid unnecessary shell re-exec
        * tests/init.sh: Improve the re-exec-required check to first test the
        current shell.  If it passes the test, do not search for a shell that
        does pass, and do not re-exec.  This test is particularly contorted to
        avoid triggering misbehavior in Solaris 10's /bin/sh whereby any use
        of $(...) evokes a syntax error and causes immediate shell exit with
        status 2.  Bruno Haible reported that the re-exec made it impossible
        to single-step through any init.sh-using script.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        Fix collision between gnulib's and libintl's printf replacements.
        * lib/stdio.in.h (_GL_STDIO_STRINGIZE,
        _GL_STDIO_MACROEXPAND_AND_STRINGIZE): New macros.
        (printf): When using GNU C, map the __printf__ function to rpl_printf
        via __asm__. When not using GNU C, define rpl_printf instead of
        __printf__.
        * lib/printf.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2010-03-25
        commit.
        * lib/stdio-write.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2009-08-10
        commit.
        * m4/asm-underscore.m4: New file.

        * modules/stdio (Files): Add m4/asm-underscore.m4.
        (Makefile.am): Substitute ASM_SYMBOL_PREFIX.
        Reported by Ben Pfaff.

2010-05-16  Bruno Haible  <bruno@clisp.org>

        verify: Avoid skipping the test on openSUSE 11.0.
        * tests/test-verify.sh: Unset MALLOC_PERTURB_.

2010-05-13  Bruno Haible  <bruno@clisp.org>

        Avoid useless warnings from G++.
        * build-aux/c++defs.h (_GL_CXXALIASWARN_2, _GL_CXXALIASWARN1_2): Don't
        use _GL_WARN_ON_USE or _GL_WARN_ON_USE_CXX when optimizing.
        Reported by Jarno Rajahalme <jarno.rajahalme@nsn.com>.

        maint.mk: tweak preceding change
        * top/maint.mk (gl_extract_significant_defines_): Make exclusion
        regexps tighter by anchoring at EOL, and make the new group "shy"
        for slightly decreased overhead.

2010-05-11  Eric Blake  <eblake@redhat.com>

        maint.mk: gnulib doesn't guarantee NSIG
        * top/maint.mk (gl_extract_significant_defines_): Exclude NSIG.

2010-05-10  Peter O'Gorman  <pogma@thewrittenword.com>

        test-pwrite.c: Remove unused variable declaration.

        Remove useless test-pwrite.sh file.
        * tests/test-pwrite.sh: Delete file.
        * modules/pwrite-tests: Remove references.
        Reported by Bruno Haible.

2010-05-10  Peter O'Gorman  <pogma@thewrittenword.com>

        init.sh: fix a typo
        * tests/init.sh: Correct typo in MALLOC_PERTURB_ initialization.

2010-05-10  Jim Meyering  <meyering@redhat.com>

        maint.mk: avoid using a temporary file in the always-defined-macros check
        * top/maint.mk (.re-defmac): Remove rule.
        (gl_trap_): Remove definition.
        (sc_prohibit_always-defined_macros): Rewrite not to create and
        depend on a temporary file.  Instead, depend on GNU grep's ability
        to read a list of regular expressions from stdin when given "-f -".

2010-05-09  Bruno Haible  <bruno@clisp.org>

        Update to GNU gettext 0.18, part 1.
        * m4/gettext.m4: Update to GNU gettext 0.18.
        * m4/intl.m4: Likewise.
        * m4/po.m4: Likewise.
        * modules/gettext (Files): Add m4/fcntl-o.m4.
        (configure.ac): Require gettext infrastructure from version 0.18.

2010-05-09  Jim Meyering  <meyering@redhat.com>

        init.sh: enable MALLOC_PERTURB_
        * tests/init.sh: Enable glibc's malloc-perturbing option.

        maint.mk: improve sc_cross_check_PATH_usage_in_tests
        With my recent change in init.sh from the two-line form:
            -#   : ${srcdir=.}
            -#   . "$srcdir/init.sh"; path_prepend_ .
            +#   . "${srcdir=.}/init.sh"; path_prepend_ .
        I noticed that using the one-line form would cause this test
        to fail with a false-positive, or to stop working altogether,
        depending on whether help-version changed or all the tests did.
        * top/maint.mk (_hv_regex): Remove this definition.
        (_hv_regex_weak): Use a weak regex to select all init.sh-sourcing files.
        (_hv_regex_strong): Use a stronger regex to check for conformance.
        (sc_cross_check_PATH_usage_in_tests): Rewrite to use the above.
        Give a separate diagnostic for lack of conforming use.

        maint.mk: prohibit definition of symbols defined by gnulib

        the GL_* versions, to avoid collision with OpenGL.

        than testing merely whether it's defined.

        Modify verify.h to pacify gcc -Wredundant_decls.
        * lib/verify.h (GL_CONCAT, GL_CONCAT0, GL_GENSYM): New macros.
        These use the prefix "GL_" since they're likely to be useful elsewhere.
        We may need to break them out into a different .h file.
        (__COUNTER__): Define to 0 if the compiler doesn't support it.
        (verify) [!defined __cplusplus]: Use them to avoid duplicate decls
        of verify_function__.

        init.sh: simply unset TMPDIR rather than risking env -i
        * tests/init.sh (mktempd_): Using env -i is rather harsh, and
        although it probably works fine on all Unix-based systems, some

        Suggestion from Eric Blake.

        regcomp.c: make non-_LIBC implementation of build_range_exp consistent
        The _LIBC implementation of build_range_exp correctly honors the
        RE_NO_EMPTY_RANGES flag when checking for reversed range endpoints.
        However, the non-_LIBC implementation would ignore that syntax-bit
        flag and return REG_ERANGE unconditionally.
        This change makes it honor that flag.
        * lib/regcomp.c (build_range_exp) [!_LIBC]: Add a parameter: "syntax".
        Make two pointer parameters "const".
        Use "syntax" bits in order to honor RE_NO_EMPTY_RANGES.

        * tests/init.sh: Re-exec a better shell, when needed.
        If the current shell lacks support for posix $(...), an init.sh-using

        substitutions like ${var#glob}.  Failure to find such a shell results
        in a skipped test.

        Use shell variable manipulation, a la ${...%.exe}, rather than sed.
        Suggestions from Eric Blake.

        init.sh: automatically accommodate programs with the .exe suffix
        Automatically arrange for an invocation of "prog" to execute the
        program named "prog$EXEEXT" (usually prog.exe).  Thus, all invocations
        may use the simpler "prog", yet still work when built on a system
        that requires specifying the added suffix.
        Do this by constructing a function named "prog" that invokes
        "prog.exe" for each .exe file in selected directories.
        * tests/init.sh (find_exe_basenames_): New function.
        (create_exe_shim_functions_): New function.

        define STREQ(a,b) consistently, removing useless parentheses
        #define STREQ(a, b) (strcmp ((a), (b)) == 0) is over-parenthesized,
        since the only risk is that "a" or "b" contains an unparenthesized
        comma, but if either did that, STREQ would have 3 or more arguments.
        Hence, #define STREQ(a, b) (strcmp (a, b) == 0) is better.

        update nearly all FSF copyright year lists to include 2009
        The files named by the following are exempted:
            grep -v '^#' config/srclist.txt|grep -v '^$' | while read src dst; do
              test -f "$dst" && { echo "$dst"; continue; }

              echo "$dst"/$(basename "$src")
            done > exempt
            git ls-files tests/unictype >> exempt
        In the remaining files, convert to all-interval notation if
        - there is already at least one year interval like 2000-2003
        - the file is maintained by me
        - the file is in lib/uni*/, where that style already prevails
        Otherwise, use update-copyright's default.

        the empty string argument.
        * lib/fts.c (fts_open): Do not let the presence of an empty string

2009-11-26  Jim Meyering  <meyering@redhat.com>

        init.sh: accommodate even those who specify bogus srcdir manually
        * tests/init.sh: Normally, srcdir is guaranteed by automake and
        configure-time tests to be sanitized, so that there is no need to
        use "$srcdir" in Makefile rules and shell scripts.  Using $srcdir
        (with no double quotes) suffices.  However, since tests may be
        invoked manually, and since you may explicitly set srcdir to the
        name of a directory containing spaces, do quote its uses here.
        * tests/test-pread.sh: Likewise.
        Suggested by Bruno Haible.

        test-pread.sh: avoid diagnostics for those who ignore SIGPIPE
        * tests/test-pread.sh: Write no data into the pipe, because
        test-pread actually reads none.  This avoids a diagnostic,
        "bash: echo: write error: Broken pipe", that arises in the unusual
        event something is ignoring SIGPIPE, and might be interpreted
        as some sort of failure.  Reported by Bruno Haible.

        m4: stylistic-only: hoist AC_SUBST to be adjacent to initialization
        Declare a variable like LIB_CLOCK_GETTIME to be AC_SUBSTituted
        right after its initialization, rather than farther down.
        Keeping these in close proximity makes it easier to ensure
        that each such variable is initialized.  E.g.,

            LIB_CLOCK_GETTIME=
            AC_SUBST([LIB_CLOCK_GETTIME])

        don't let environment settings perturb build
        Setting the envvars, LIB_CLOCK_GETTIME, LIB_EACCESS or LIB_NANOSLEEP
        could cause a configure-time and/or build-time malfunction.
        Typically, a configure-time function-in-library test is performed
        via code like this:

          LIB_VAR=
          AC_SUBST([LIB_VAR])
          prefix_saved_LIBS=$LIBS
            AC_SEARCH_LIBS([FUNC], [LIB_NAME],
                       [test "$ac_cv_search_FUNC" = "none required" ||
                        LIB_VAR=$ac_cv_search_FUNC])
          LIBS=$prefix_saved_LIBS

        However, in each of the files affected by this change, the LIB_VAR=
        initialization was omitted.  Thus, when set in the environment, its
        value would propagate into generated Makefiles when FUNC is not found
        in LIB_NAME.

        Replace uses of obsolete autoconf macros in Jim's modules.
        The Autoconf macros AC_TRY_CPP, AC_TRY_COMPILE, AC_TRY_LINK and
        AC_TRY_RUN have been obsolete since Autoconf 2.55, and each use
        can evoke a warning from autoconf when run with -Wobsolete
        enabled.  They were declared obsolete for good reasons (see
        the `AC_FOO_IFELSE vs AC_TRY_FOO' node in the Autoconf manual,
        recently renamed to `AC_ACT_IFELSE vs AC_TRY_ACT'), and we

        vc-list-files: avoid failure when /bin/sh is dash
        * build-aux/vc-list-files: Avoid a shell portability problem with dash.
        On some Debian based systems, /bin/sh is a symlink to dash, and running

        That is because bash and dash work differently:
          $ for i in bash dash; do $i -c 'a=odd; a=ok b=$a; echo '$i' $b'; done
          bash ok

        version-etc: extend for packagers
        Add three new configure options, intended for packagers:
          --with-packager="packager name"
          --with-packager-version="packager-specific version"
          --with-packager-bug-reports="packager bug reporting"
        An example with coreutils:
          $ ./configure \
            --with-packager=Gentoo \
            --with-packager-bug-report=http://bugs.gentoo.org/ \
            --with-packager-version="patchset 1.6"
          $ ./src/ls --version | head -n2
          ls (GNU coreutils) 7.1-dirty
          Packaged by Gentoo (patchset 1.6)
        Note that the bug reporting info via --help doesn't show up because
        coreutils uses its own custom emit_bug_reporting_address() implementation
        in src/system.h.  If it didn't, it'd look like:
          $ ./src/ls --help | tail -n4

        Port coreutils 7.2 to Solaris 8.

        * modules/arpa_inet (arpa/inet.h): Depend on arpa_inet.in.h.
        * m4/inet_ntop.m4 (gl_INET_NTOP): Search for inet_ntop in -lnsl,
        for Solaris 8.  This is a bit of a hack, as it means it's the
        caller's responsibility to add -lnsl if needed, but most likely it
        won't be needed since only getaddrinfo uses this and getaddrinfo
        isn't needed on Solaris 8.

        * modules/fnmatch (Depends-on): Add mbsrtowcs, to fix a porting
        problem to Solaris 8 encountered with coreutils 7.2, which
        resulted in a message "fnmatch.c:292: warning: passing argument 4
        of 'mbsrtowcs' from incompatible pointer type".  Also, add mbsinit
        at the suggestion of Bruno Haible, since fnmatch uses mbsinit.

2009-02-13  Jim Meyering  <meyering@redhat.com>

        fts: arrange not to stat non-directories in more cases
        This makes GNU find (when it doesn't need to stat each file)
        *much* more efficient at traversing reiserfs file systems.
        * lib/fts_.h (struct ftsent) [fts_n_dirs_remaining]: New member.
        (struct FTS) [fts_leaf_optimization_works_ht]: Add member.

        (S_MAGIC_REISERFS, S_MAGIC_PROC): Define.
        (leaf_optimization_applies): New function.
        (LCO_hash, LCO_compare): New helper functions.
        (link_count_optimize_ok): New function.
        (fts_stat): Initialize new member (if dir).
        (fts_read): Decrement parent's fts_n_dirs_remaining count if
        we've just stat'ed a directory.  Skip the stat call when possible.
        ---
        Note this AFS-related exchange:
        http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=143111
        and note find's pioctl call in find/fstype.c.
        But that is necessary only if you want to enable the
        optimization for AFS, and for now, I don't.

        fts: move a function definition "up" (no semantic change)

        many *.m4 files: improve m4 quoting
        99% of this change was performed by running the following commands:
        git ls-files | grep '\.m4$' | xargs perl -pi \
          -e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
          -e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
        perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
        The remainder were to add Copyright dates, increment serial numbers,
        undo some changes in comments, exclude m4/intl.m4, and add quotes
        around the "1" in ",1" where the unusual spacing prohibited the
        above regexps from doing the job.  For more details, see

2008-12-21  William Pursell  <bill.pursell@gmail.com>

        gitlog-to-changelog: pass all command-line arguments to git-log
        * build-aux/gitlog-to-changelog: When producing a ChangeLog,
        it is sometimes convenient to filter the commits in various ways.
        gitlog-to-changelog only allows --since to specify a start date,
        but git-log itself supports many other filtering mechanisms.
        At the moment, I want to filter by branch name.  Rather than
        adding a --branch option to gitlog-to-changelog, it seems more
        flexible to simply pass all options directly to git-log and let
        git do the work.  Notice that this effectively makes --since a
        redundant option for gitlog-to-changelog, but removing it would
        require current usage to change since calls would then require
        an additional '--'.

        Add support for Solaris 10 ACLs.  Also, ACLs are Gnulib, not Autoconf.
        * modules/acl (configure.ac): Rename AC_FUNC_ACL to gl_FUNC_ACL.
        * m4/acl.m4 (gl_FUNC_ACL): Renamed from AC_FUNC_ACL.  On Solaris,
        put -lsec in even for programs other than 'ls'.  This fixes a problem
        for gettext reported by Bruno Haible in

        * lib/unictype/pr_byname.c: Include unictype/pr_byname.h instead of
        pr_byname.h. Needed for the rare case when the maintainer has done
        "make maintainer-clean" in the source directory and then attempts a
        build outside the source directory.
        * lib/unictype/scripts.c: Include unictype/scripts_byname.h instead of
        scripts_byname.h.

        * lib/regcomp.c (optimize_utf8): Fix a typo, s/idx/ctx_type/,
        that would inhibit utf8-optimization of a regexp containing line-
        or buffer-anchors, e.g., `^', `$'.

2007-11-30  Bruno Haible  <bruno@clisp.org>

        Adjust getdate' grammar to accept a slightly more regular language.
        E.g., accept "YYYYMMDD +N days" as well as "YYYYMMDD N days".
        Before, the former was rejected.
        * lib/getdate.y (digits_to_date_time): New function, factored
        out of ...
        (number): ...here.  Just call digits_to_date_time.
        (hybrid): New non-terminal to handle an <unsigned number,
        signed relative offset> sequence consistently.

2007-11-18  Jim Meyering  <meyering@redhat.com>

        Pull my changes from coreutils:
        bootstrap: fix typo to enable use of $gnulib_tool_option_extras.
        * build-aux/bootstrap (gnulib_tool_options): Add a space before the
        use of $gnulib_tool_option_extras, so that it's separated from the
        preceding argument.

        Fix bootstrap failure to handle files like lib/uniwidth/cjk.h.
        * build-aux/bootstrap (cp_mark_as_generated): Create any required
        parent destination directories before copying a file into place.

2007-11-18  Sergey Poznyakoff  <gray@gnu.org.ua>

        bootstrap: work also with 4-argument variant of AC_INIT
        * build-aux/bootstrap (gnulib_extra_files): Adjust sed command.

2007-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        Problem reported by Bruno Haible in
        <http://lists.gnu.org/archive/html/bug-gnulib/2007-03/msg00171.html>.
        * tests/test-getaddrinfo.c (simple): Add a comment asking for an
        explanation of setting 'hints'.
        Don't reject an implementation merely because it returns EAI_SERVICE.
        (EAI_SERVICE): Define to 0 if not defined.

2007-11-15  Paul Eggert  <eggert@cs.ucla.edu>

        The license of gnu-make and posix-shell is now "GPLed build tool".
        * modules/gnu-make (License): Likewise.
        * modules/posix-shell (License): Likewise.

        New module posix-shell, for determining a POSIX shell
        or perhaps something that is close enough to a POSIX shell.
        * m4/posix-shell.m4: New file.
        * modules/posix-shell: New file.

        * MODULES.html.sh: Mention new module.

        New module gnu-make, for determining whether we're using GNU Make.
        * m4/gnu-make.m4: New file.
        * modules/gnu-make: New file.
        * MODULES.html.sh: Mention new module.

2007-11-14  Jim Meyering  <meyering@redhat.com>

        Define a sometimes-link-required function using ARGMATCH_DIE_DECL.
        * tests/test-argmatch.c (ARGMATCH_DIE_DECL): When defined,
        use this macro to create a function _definition_.
        Remove useless "#undef ARGMATCH_DIE".

2007-11-14  Bruno Haible  <bruno@clisp.org>

        * lib/config.charset: Update for OpenBSD 4.1.
        Reported and helped by Ben Pfaff <blp@cs.stanford.edu>.

2007-11-12  Paul Eggert  <eggert@cs.ucla.edu>

        Document 64-bit #if problems in stdint.texi.
        * doc/headers/stdint.texi (stdint.h): Mention problems with
        64-bit-#if, and how to work around them.

        Don't insist on 'long long int' support in the preprocessor.  It
        breaks too many things.  For example, PRIdMAX still uses a 'long
        long int' format with the latest Sun compiler, even though
        HAVE_LONG_LONG_INT isn't defined due to that compiler's
        preprocessor problem.  This causes the latest coreutils to dump
        core on Solaris 10 sparc with the Sun C compiler.
        Instead, fix the 2007-10-16 problem in a different way, by evaluating
        the troublesome expressions at configure-time, not at #if-time.
        * m4/longlong.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Don't test the
        preprocessor.
        * m4/inttypes.m4 (gl_INTTYPES_H): Move the #if checks into
        compile-time C checks, done at 'configure'-time.
        (gl_INTTYPES_CHECK_LONG_LONG_INT_CONDITION): New macro.
        * modules/inttypes (Makefile): Substitute the new symbols that
        gl_INTTYPES_H now generates.
        * lib/inttypes.in.h: Don't use constants wider than 'long' in #if.

        Simplify and modernize strerror substitute, partly to fix Solaris 8 bug.

        * lib/strerror.c: Include <string.h> always, to test interface,
        and to remove the need for the dummy.

        (rpl_strerror): Use INT_STRLEN_BOUND to compute bound.

        * build-aux/bootstrap (slurp): Work even in environments where

        * build-aux/bootstrap (symlink_to_dir): If the destination

        depends on it.
        (xstrtol_error): Remove.

        but with a different signature.

        Schwab in
        <http://lists.gnu.org/archive/html/bug-gnulib/2007-02/msg00261.html>.

        * lib/getcwd.c (__getcwd): Don't assume getcwd (NULL, 0) works
        like glibc; on Solaris 10, it fails with errno == EINVAL.
        POSIX says the behavior is unspecified if the first argument is NULL,
        so play it safe and never pass NULL to the system getcwd.

2007-02-21  Jim Meyering  <jim@meyering.net>

        do not have the desired effect in multibyte locales; instead, use
        mbscasecmp.
        * modules/exclude (Depends-on): Depend on mbscasecmp, not strcase.
        Add dependency on xalloc.  Depend on fnmatch, not fnmatch-gnu, since
        we don't require GNU fnmatch ourselves (if our users require it, they

2007-02-12  Paul Eggert  <eggert@cs.ucla.edu>

        New module 'time', so that apps can include <time.h> as per
        POSIX and GNU instead of separate include files like time_r.h
        and timegm.h.  This implementation tries out a simpler approach
        for replacing decls in standard include files (as compared to
        the string module), somewhat as an experiment.

        * config/srclist.txt: Comment out mktime.c for now.
        * doc/gnulib-tool.texi (Initial import): Don't use time_r as an example
        since it doesn't apply any more.  Use generic wording instead.
        * MODULES.html.sh (Support for systems lacking POSIX:2001): New module
        'time'.

        (struct timespec, nanosleep): Remove; time.h now arranges for these.
        * lib/xnanosleep.c: Don't include timespec.h; no longer needed now
        that time.h defines struct timespec.
        * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Check that nanosleep is declared.
        Set REPLACE_NANOSLEEP.  Don't AC_DEFINE nanosleep; the time module now
        handles that.
        * m4/strptime.m4 (gl_FUNC_STPRTIME): Set REPLACE_STRPTIME.
        * m4/time_r.m4 (gl_TIME_R): Don't define HAVE_TIME_R_POSIX; no longer
        needed.  Set REPLACE_LOCALTIME.
        * m4/timegm.m4 (gl_FUNC_TIMEGM): Set REPLACE_TIMEGM.
        * m4/timespec.m4 (gl_CHECK_TYPE_STRUCT_TIMESPEC): Move to time_h.m4.
        (gl_TIMESPEC): Don't check for sys/time.h or struct timespec or
        nanosleep; time_h.m4 now does that.  Don't require
        gl_USE_SYSTEM_EXTENSIONS; no longer needed directly, and the time
        module handles this now.
        * modules/getdate (Depends-on): Remove timespec.  Add time.

        * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Also
        replace gettimeofday.
        * lib/gettimeofday.c (rpl_gettimeofday): Declare with replacement
        name, to avoid infinite recursion.

2007-01-17  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh (Support for systems lacking POSIX:2001): New
        module sys_time.
        * lib/gethrxtime.c: Include <sys/time.h>, since we can no longer
        assume timespec.h defines struct timeval.
        * lib/settime.c: Likewise.
        * lib/utimens.c: Likewise.
        * lib/gettime.c (gettime): Remove test against HAVE_GETTIMEOFDAY,
        since we now assume the gettimeofday module.
        * lib/tempname.c (__gen_tempname): Likewise.
        * lib/gettimeofday.h: Remove.
        * lib/gettimeofday.c: Include <sys/time.h> instead of "gettimeofday.h".
        Don't include <sys/types.h> and <stdlib.h>; shouldn't be needed.
        Include <time.h>, for 'time()'.
        (localtime_buffer_addr): Also use this workaround if
        TZSET_CLOBBERS_LOCALTIME.  Set to a dummy static variable by default,
        to simplify the uses.  All uses changed.
        (localtime, gmtime, tzset, gettimeofday): Reformat slightly so
        that #undef is inside {}, and 'const' follows type name consistently.
        (tzset): Define replacement only if TZSET_CLOBBERS_LOCALTIME.
        (gettimeofday): Do not use the maximum possible value for
        tv->tv_usec, since that might break usages other than ls.c.
        Instead, we'll leave ls.c alone.  This undoes today's patch
        by Bruno.  Add a compile-time warning for 1s-clock resolution;
        we've never observed the problem but might as well keep the
        canary.
        * lib/nanosleep.c: Include timespec.h first, for interface check.
        * lib/nanosleep.c: Include <sys/time.h> unconditionally, since we
        now assume the sys_time module.
        * lib/tempname.c: Likewise.
        * lib/timespec.h: Likewise.
        * lib/nanosleep.c: Don't worry about TIME_WITH_SYS_TIME; no longer
        needed.
        * lib/strftime.c: Likewise.
        * lib/timespec.h: Likewise.
        * lib/posixtm.c: Include posixtm.h first, for interface check.
        Don't worry about TM_IN_SYS_TIME; that's wayyy obsolete.
        * lib/posixtm.h: Include stdbool.h and time.h, for proper interface.
        * lib/strftime.c: Don't include <sys/types.h>; shouldn't be needed.
        * lib/sys_time_.h: New file.
        * lib/timespec.h (struct timespec): Use long int, not long.
        * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY):
        (gl_FUNC_GETTIMEOFDAY_CLOBBER, gl_PREREQ_GETTIMEOFDAY):
        Remove obsolescent call to AC_HEADER_TIME.
        * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise.

        * m4/utimbuf.m4 (gl_CHECK_TYPE_STRUCT_UTIMBUF): Likewise.
        * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): Move sys/time.h tests
        into the sys_time module.  Check for gettimeofday just once.
        Prefix our variables with gl_, not with ac_ or jm_.  Tighten test
        for gettimeofday signature to just check the signature.  Merely
        compile it, since linking doesn't test signature.  Improve test for
        whether gettimeofday.o is actually needed.
        (gl_FUNC_GETTIMEOFDAY_CLOBBER): Renamed from
        AC_FUNC_GETTIMEOFDAY_CLOBBER.  All uses changed.  Use
        AC_RUN_IFELSE rather than AC_TRY_RUN.  If clobbering, set
        and define GETTIMEOFDAY_CLOBBERS_LOCALTIME.
        (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Don't define
        GETTIMEOFDAY_CLOBBERS_LOCALTIME; that's gl_FUNC_GETTIMEOFDAY_CLOBBER's
        job.  Don't define tzset; that's gl_FUNC_TZSET_CLOBBER's job.
        * m4/mktime.m4 (AC_FUNC_MKTIME): Just include <time.h> rather
        than worrying about sys/time.h.
        * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP):
        Don't bother worrying about TIME_WITH_SYS_TIME.
        * m4/stat-time.m4 (gl_STAT_TIME): Likewise.
        * m4/posixtm.m4 (gl_POSIXTM): Remove obsolescent call to AC_STRUCT_TM.
        * m4/sys_time_h.m4: New file.
        * m4/tzset.m4 (gl_FUNC_TZSET_CLOBBER): Require gl_HEADER_SYS_TIME_H.
        Don't include sys/time.h.  Return from main rather than exiting.
        Define TZSET_CLOBBERS_LOCALTIME, for consistency with other names;
        all uses changed.
        * modules/gethrxtime (Depends-on): Add sys_time.
        * modules/gettime (Depends-on): Likewise.
        * modules/gettimeofday (Depends-on): Likewise.

        rather than gettimeofday.h.

2007-01-17  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_get_license): Revert last patch. Instead, let
        the license default to GPL.
        (func_create_testdir): Don't complain if a module is LGPL and its
        tests module depends on GPLed modules.

2007-01-08  Bruno Haible  <bruno@clisp.org>

        * m4/lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Simplify the sorting
        command.

2007-01-08  Jim Meyering  <jim@meyering.net>

        Use a more robust test for a "can't happen" condition.
        * lib/fts.c (fts_read): Revert the change of 2006-11-22, since it
        narrowed the st_size value.  Presuming the "can't happen" condition
        is true, that narrowing could conceivably convert an invalid st_size
        value into a valid one.  Instead, use a change based on Matthew
        Woehlke's original patch.

        Slight readability improvement: use an assert-like macro
        in place of literal "abort ()" uses.
        * lib/fts.c (fts_assert): Define.
        (fts_set_stat_required, cwd_advance_fd, fts_read, fd_ring_check):
        Use this macro instead of a bare 'abort'.

2007-01-05  Paul Eggert  <eggert@cs.ucla.edu>

        Don't worry about using IRIX 5.3's wctype.h broken definitions;
        simply work around them.
        * lib/wctype_.h: Remove test for HAVE_WCTYPE_CTMP_BUG.
        (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph, iswlower):
        (iswprint, iswpunct, iswspace, iswupper, iswxdigit): Undef before
        declaring.
        Don't bother to define as macros, since the standard doesn't require it.
        * m4/wctype.m4 (WCTYPE_H, ABSOLUTE_WCTYPE_H): Simplify, since we no
        longer worry about IRIX 5.3.
        (HAVE_WCTYPE_CTMP_BUG): Remove.

2007-01-04  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/wctype_.h (_ctmp_) [HAVE_WCTYPE_CTMP_BUG]: Now of type wchar_t,

        * lib/poll.c (poll): Use recv on Mac OS X to distinguish connected
        sockets, server sockets, and other file descriptors.  Count errors
        to compute the return value.  Reorder the code a bit to be easier
        to follow.  Don't set event bits that were not requested (except
        POLLERR and POLLHUP).

2006-12-30  Paul Eggert  <eggert@cs.ucla.edu>

        * gnulib-tool (SORT): Remove, since we no longer assume GNU sort.
        Rewrite so as not to assume GNU sort or "tail -1".  Also, don't
        assume the C locale, and avoid an "eval" that could cause trouble.
        Problem with SORT reported by Bob Proulx.

        * lib/getpagesize.h (getpagesize) [defined __amigaos4__]:
        Define.  Trivial patch from Henning Nielsen Lund, originally

2006-12-27  Eric Blake  <ebb9@byu.net>

2006-12-25  Paul Eggert  <eggert@cs.ucla.edu>

        * gnulib-tool (SED): Remove, undoing previous change.
        The problem was that it broke coreutils on Solaris, because
        "sed --posix" leaked into a makefile.
        (sed): New alias, if 'alias' and GNU sed.

2006-12-24  Jim Meyering  <jim@meyering.net>

        Work around an fchownat bug in glibc-2.4:
        http://lists.ubuntu.com/archives/ubuntu-users/2006-September/093218.html
        This bug would cause "chown -RP ... DIR" to follow symlinks in DIR,
        in spite of the -P option.
        * m4/openat.m4 (gl_FUNC_FCHOWNAT, gl_FUNC_FCHOWNAT_DEREF_BUG):
        New macros.
        (gl_PREREQ_OPENAT): Require gl_FUNC_FCHOWNAT.
        * modules/openat (Files): Add lib/fchownat.c.
        * lib/openat.c (fchownat): Don't define here.  Move to...
        * lib/fchownat.c: ...this new file.

2006-12-23  Paul Eggert  <eggert@cs.ucla.edu>

        Fix bug reported by Bruno Haible in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00228.html>
        where quotearg.c didn't compile on Mac OS X 10.2 because it
        lacks <wchar.h> and wint_t.
        * lib/wctype_.h (__wctype_wint_t): New type.
        Include <stdio.h>, <time.h>, <wchar.h> only if HAVE_WINT_T.
        (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph):
        (iswlower, iswprint, iswpunct, iswspace, iswupper, ixwxdigit):
        Arg is now of type __wctype_wint_t, not wint_t.
        * m4/wctype.m4 (gl_WCTYPE_H): Require gt_TYPE_WINT_T, and
        substitute HAVE_WINT_T.
        * modules/wctype (Files): Add m4/wint_t.m4.
        (wctype.h): Substitute HAVE_WINT_T.

2006-12-23  Bruno Haible  <bruno@clisp.org>

        * lib/safe-read.h [C++]: Wrap declarations in extern "C".

2006-12-23  Bruno Haible  <bruno@clisp.org>

        * lib/canonicalize-lgpl.c (__realpath): Test HAVE_READLINK instead of
        S_ISLNK.
        Needed because gnulib's sys/stat.h replacement defines S_ISLNK on
        mingw.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * lib/copy-file.c: Include acl.h.
        (copy_file_preserving) [USE_ACL]: Use copy_acl instead of chmod.
        Close the file descriptors only after being done with copy_acl.
        * modules/copy-file (Depends-on): Add acl.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (SED): New variable.
        Use $SED instead of sed everywhere.

2006-12-22  Bruno Haible  <bruno@clisp.org>

        * modules/no-c++: New file.
        * m4/no-c++.m4: New file.
        * MODULES.html.sh (Support for building libraries and executables):
        Add no-c++.

2006-12-22  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf.
        Include <limits.h>, and use its INT_MAX to rewrite the
        j loop so that it does not overflow 'int'.  Problem reported by
        Ralf Wildenhues in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
        Play it safe by shifting left by 1 rather than multiplying by 2,
        as GCC is less likely to optimize this away when the value
        is signed (when it assumes overflow leads to undefined behavior).
        Also, don't assume time_t uses two's complement.

2006-12-21  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh: New module wctype.
        * lib/wctype_.h, m4/wctype.m4, modules/wctype: New files.
        * lib/fnmatch.c: Don't bother to include <wchar.h> before
        <wctype.h>, since the new wctype module should fix this.
        * lib/quotearg.c: Include <wctype.h> unconditionally, since
        the wctype module should arrange for it.
        * lib/regex_internal.h: Likewise.
        * m4/quotearg.m4 (gl_QUOTEARG): Don't check for wctype.h or iswprint,
        since the wctype module should handle this now.
        * m4/regex.m4 (gl_PREREQ_REGEX): Don't check for wctype.h.
        * modules/fnmatch (Depends-on): Add wctype.
        * modules/quotearg (Depends-on): Likewise.
        * modules/regex (Depends-on): Likewise.

2006-12-19  Bruno Haible  <bruno@clisp.org>

        * lib/strdup.h [C++]: Wrap definitions in extern "C".
        Suggested by Lorenzo Bettini <bettini@dsi.unifi.it>.

2006-12-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * modules/savewd (Depends-on): Fix dependency on fcntl.

2006-12-18  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Set STDINT_H to empty if stdint.h
        conforms to C99, rather than relying on the user's environment
        setting of STDINT_H.

2006-12-18  Paul Eggert  <eggert@cs.ucla.edu>
        and Eric Blake  <ebb9@byu.net>

        * lib/dirname.h (DOUBLE_SLASH_IS_DISTINCT_ROOT): Default to 0, not 1.
        This is more consistent with the other defines here.
        * m4/double-slash-root.m4 (gl_DOUBLE_SLASH_ROOT):
        Port to z/OS.  Problem reported by Paul Gilmartin.
        Change local vars to use gl_ prefix rather than ac_.
        Don't define DOUBLE_SLASH_IS_DISTINCT_ROOT to 0, for consistency
        with other defines.
        * modules/double-slash-root: New module.
        * modules/dirname (Files): Remove m4/double-slash-root.m4.
        (Depends-on): Add double-slash-root.
        * MODULES.html.sh (File system functions): Mention new module.

2006-12-14  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/yesno.c [!ENABLE_NLS]: Don't include getline.h.
        (yesno) [!ENABLE_NLS]: Don't invoke getline or rpmatch.
        This is for the benefit of gzip, which doesn't do i18n.

2006-12-12  Jim Meyering  <jim@meyering.net>

        * m4/acl.m4 (gl_ACL_GET_FILE): Fix logic error.
        Reported by Andreas Schwab <schwab@suse.de>.

2006-12-12  Bruno Haible  <bruno@clisp.org>

        Merge these changes.
        2006-09-05  Bruno Haible  <bruno@clisp.org>
        * lib/iconvme.c (iconv_string): No need to save and restore errno when
        iconv_alloc succeeded.
        (iconv_alloc): Don't assume that malloc() or realloc(), when failing,
        sets errno to ENOMEM. (malloc on GNU/kFreeBSD doesn't.) No need to
        test for " && dest " at the end - dest is always != NULL there. Call
        iconv with 4xNULL arguments initially, to reset the state. Call iconv
        with 2xNULL arguments, also to flush the state storage. Handle the
        IRIX iconv behaviour. Realloc the final result, to throw away unused
        memory.

2006-12-11  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/openat.m4 (gl_FUNC_OPENAT): Don't compile mkdirat
        and fchmodat unconditionally, since glibc 2.4 has them.
        Problem reported by Arkadiusz Miskiewicz.

2006-12-10  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Show the include files only for those
        modules that are copied and specified.
        Reported by Karl Berry.

2006-12-08  Jim Meyering  <jim@meyering.net>

        * build-aux/announce-gen ($VERSION): Don't use of $Revision...$.
        Instead, use Emacs' time-stamp write hook.  Note that the time is UTC.

        * build-aux/announce-gen: Add two new options, both optional:
        --bootstrap-tools=TOOL_LIST
              a comma-separated list of tools, e.g.,
              autoconf,automake,bison,gnulib
        --gnulib-snapshot-date=DATE
              if gnulib is in the bootstrap tool list,
              then report this as the snapshot date.
              If not specified, use the current date/time.
              If you specify a date here, be sure it's UTC.

2006-12-05  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * tests/test-argp-2.sh: Fix test to match actual output.
        (func_compare): Fix sed script to be portable.

2006-12-05  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (futimens) [HAVE_BUGGY_NFS_TIME_STAMPS]: Add a
        workaround for this case.  It is not autoconfigured now; offhand
        it's hard to see how to autoconfigure it.

2006-12-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mkdir-p.c (make_dir_parents): Fix race condition when making
        a directory that is about to be chowned.  Such a directory's
        initial file permissions should permit the owner only and this
        should not be changed until after the chown, since the group and
        other bits would be incorrect if they granted permission before
        the chown.

        Fix porting problem for iswctype reported by Georg Schwarz in:
        http://lists.gnu.org/archive/html/bug-coreutils/2006-12/msg00017.html

2006-12-03  Jim Meyering  <jim@meyering.net>

        * lib/fts.c (fts_load): Don't set sp->fts_dev here, since
        p->fts_statp may not yet be defined.
        (fts_read): Instead, set it in the caller, once p->fts_statp is
        sure to be defined, and corresponds to a top-level directory.
        This bug made du -x fail.  Here's the coreutils test case:

        build failure due to missing definition of HAVE_WORKING_O_NOFOLLOW.
        Reported by Simon Josefsson.

2006-11-30  Jim Meyering  <jim@meyering.net>

        if compiling pedantically with GCC, unless it's C99 or later.

        it mishandles gcc -ansi -pedantic as well.
        * lib/regex_internal.h (re_token_t): Don't use enum bitfields
        if gcc -pedantic.

        (fstatat): Define to rpl_fstatat under the same conditions,
        unless COMPILING_FSTATAT.

        be more accurate, and to be consistent with one another.

2006-11-20  Jim Meyering  <jim@meyering.net>

        * lib/idcache.c: Restore most of the 2006-11-06 patch, so as to
        continue using the flexible array member (thus, this module performs
        half as many malloc calls), with the addition that...
        (getgroup, getuser): Consistently record a non-match via an empty
        "name" string, and map an empty string match to a NULL return value.
        * modules/idcache (Depends-on): Re-add flexmember.

        * lib/idcache.c (getuser): Remove all uses of the register keyword.
        (getuidbyname, getgroup, getgidbyname): Likewise.

        * lib/idcache.c (getuidbyname, getgidbyname): Return NULL, not 0.

2006-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/idcache.c: Undo most recent patch, dated 2006-11-06.
        It mishandled the case where the group was missing.
        Problem reported by Greg Schafer.
        * modules/idcache: Likewise.

2006-11-18  Jim Meyering  <jim@meyering.net>

        * modules/getaddinfo (Depends-on): Remove inttostr; add snprintf.
        * lib/getaddrinfo.c: Include snprintf.h rather than intprops.h
        and inttostr.h.  Use snprintf rather than uinttostr, so that
        LGPLed code doesn't depend on GPLed.

2006-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/inline (License): Change from GPL to LGPL.

2006-11-17  Jim Meyering  <jim@meyering.net>

2006-11-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * m4/inttypes.m4 (gl_INTTYPES_H): Use AC_CACHE_CHECK so that the
        test for conforming inttypes.h is both announced and cached.

        * MODULES.html.sh (seen_modules, seen_files): New variables.
        (func_module): Rewrite to use a few less gnulib-tool and sed
        invocations.  Avoid a couple of quadratic algorithms for ...
        (missed_modules, missed_files): ... these, with ...
        (func_append, func_tmpdir): ... these new functions, from
        gnulib-tool.  Analogously, install traps for cleanup.

        * tests/test-gc.c (main): Remove unused variables.
        * tests/test-read-file.c: Include stdlib.h, for 'free'.

        subdirectories of $prefix/include.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * m4/lib-link.m4: Require at least autoconf-2.54.

        * gnulib-tool: New option --local-symlink.
        (func_usage): Document it.
        (lsymbolic): New variable.
        (func_import, func_create_testdir): If --symlink was not specified,
        test whether --local-symlink was specified and the file comes from
        the local_gnulib_dir.

2006-11-12  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_ln): New function.

2006-11-12  Jim Meyering  <jim@meyering.net>

        Make fts (in FTS_CWDFD mode) more efficient by caching a few open
        file descriptors.  This also averts a failure on systems with
        native openat support when a traversed directory lacks "x" access.
        * lib/fts_.h: Include "i-ring.h"
        (struct FTS) [fts_fd_ring]: New member.

        (cwd_advance_fd): Add a 3rd parameter.  Adjust all callers.
        When descending, rather than simply closing the previous
        fts_cwd_fd value, push that file descriptor onto the ring.
        (same_fd, fd_ring_print, fd_ring_check) [FTS_DEBUG]: New functions.
        (fts_open): Initialize the new fd_ring member.
        (fts_close): Clear the ring.
        (fts_safe_changedir): When possible, use our new fd_ring to skip
        the diropen and fstat and dev/ino comparison that would normally
        accompany a virtual `chdir ("..")'.

        * modules/fts (Depends-on): Add i-ring.
        * modules/i-ring: New module.
        * lib/i-ring.c, lib/i-ring.h, lib/i-ring-test.c: New files.

2006-11-12  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * gnulib-tool (func_create_testdir): Fix replacement of
        `build-aux' in configure.ac.  Run autotools in gltests
        subdirectory.
        (func_create_testdir, func_create_megatestdir, test): There is
        no need for '--force' in most autotool invocations in a new
        tree.  Actually fail the whole test if any of the tools, or the
        configure or make stages fail.

        Sync from Automake.
        * build-aux/gnupload: Revert last change.  Add pointer to upload
        instructions of the GNU Maintenance Instructions.
        Suggestion by Karl Berry.

        (dngettext, dcngettext, bindtextdomain) [! ENABLE_NLS]:
        (bind_textdomain_codeset) [! ENABLE_NLS]:
        Evaluate all the arguments.  That way, callers get compatible behavior
        if the arguments have side effects.  Also, it avoids some GCC
        diagnostics in some cases; Joel E. Denny reported problems when Bison
        was configured with --enable-gcc-warnigs.

2006-11-10  Jim Meyering  <jim@meyering.net>

        * m4/inline.m4 (gl_INLINE): Check with the compiler, not cpp, so that

        It's already included if !_LIBC.
        (fts_safe_changedir): Add a comment.

2006-11-07  Paul Eggert  <eggert@cs.ucla.edu>

        inline functions that are identical with the old xnmalloc_inline,
        xnrealloc_inline, x2nrealloc_inline of lib/xmalloc.c.  This is so
        that we can avoid some unnecessary integer multiplications and
        divisions in the common case where the element size is known at
        compile time.
        (XNMALLOC) [HAVE_INLINE]: Remove special case, which is no longer
        needed.
        (xnboundedmalloc): Remove.
        (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Use lower-case letters for
        arguments, for consistency with rest of this header.
        (xcharalloc): Rewrite using XNMALLOC.
        * lib/xmalloc.c (xnmalloc_inline, xnmalloc, xnrealloc_inline):
        (xnrealloc, x2nrealloc_inline, x2nrealloc): Remove.  The *_inline
        versions have been moved to lib/xalloc.h and renamed to be the
        non-*_inline versions.
        (xmalloc, xrealloc): Implement without reference to the xnmalloc
        and xnrealloc functions, since those functions are now inline and
        now call us.
        (x2realloc): Invoke x2realloc, not x2realloc_inline, to accommodate
        renaming described above.
        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Remove AC_C_INLINE since
        xmalloc.c no longer uses inline directly.  gl_PREREQ_XALLOC now
        captures the dependency in AC_C_INLINE.

        New module canonicalize-lgpl, proposed by Charles Wilson in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-11/msg00020.html>

        * lib/sigprocmask.c: New file.
        * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Renamed from

        (fatal_signal_set, init_fatal_signal_set, block_fatal_signals,
        unblock_fatal_signals): Define always.

2006-10-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from Automake.
        * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
        which incorrectly sets the mode of an existing destination
        directory.  In some cases the unpatched install-sh could do the
        equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
        system.  We hope this is rare in practice, but it's clearly worth
        fixing.  Problem reported by Alex Unleashed in
        <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
        Also, don't bother to check for -m bugs unless we're using -m;
        suggested by Stepan Kasal.

2006-10-14  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Sync from Automake.
        * build-aux/depcomp (gcc3): Put dependency extraction flags before the
        `-c' flag, so they appear at the same position as in %FASTDEP%
        mode in depend2.am.  Fixes build failure for FreeBSD's c89,
        which ignores unknown options only after the first non-option.
        Bug report against M4 by Nelson H. F. Beebe.

2006-10-13  Jim Meyering  <jim@meyering.net>

        Fix a bug in yesterday's change.
        * lib/fts.c (fts_open): When using FTS_XDEV|FTS_NOSTAT,
        p->fts_statp->st_dev would be used uninitialized.
        Ensures that we always call fts_stat on the very first entry.
        Miklos Szeredi reported that find -xdev stopped working.

        * m4/getloadavg.m4 (gl_GETLOADAVG): Test for the existence of
        lib/getloadavg.c using "ls -L", not "test -f".  The latter would
        fail with a symlink, which is what coreutils' ./bootstrap now
        creates by default.

        * gnulib-tool (func_emit_lib_Makefile_am): In the _LIBADD variable,

        with the same contents as the _LIBADD variable.
        (func_emit_initmacro_start, func_emit_initmacro_end,
        func_emit_initmacro_done): New functions.
        (func_import, func_create_testdir): Invoke them. Allow the identifiers
        gl_LIBOBJS and gl_LTLIBOBJS.

2006-10-11  Bruno Haible  <bruno@clisp.org>

        *.m4 files from gnulib.

2006-10-11  Bruno Haible  <bruno@clisp.org>

        modules.

        Big performance improvement for fts-based tools that use FTS_NOSTAT.
        Avoid spurious inode-mismatch problems on non-POSIX file systems.
        Details: http://article.gmane.org/gmane.comp.lib.gnulib.bugs/7416
        * lib/fts_.h (FTS_DEFER_STAT): Define new flag.
        (FTS_OPTIONMASK): Extend the mask to reflect this addition.
        * lib/fts.c (DT_IS_KNOWN, DT_MUST_BE): Define.
        (FTS_NO_STAT_REQUIRED, FTS_STAT_REQUIRED): Define.
        (fts_set_stat_required): New function.
        (fts_open): Defer the calls to fts_stat, if possible or requested.
        Move the code that maps a command-line fts_info value FTS_DOT to FTS_D
        into fts_stat itself.
        (fts_read): Perform any required (deferred) fts_stat call.
        (fts_build): Likewise, for the directory we're about to open and read.
        In the readdir loop, carefully decide whether each entry will require
        an eventual call to fts_stat, using dirent.d_type info if available.
        (fts_stat): Move the test for whether to honor FTS_COMFOLLOW on
        a command line argument into this function.  Update all callers.
        Map a return value of FTS_DOT to FTS_D for a command line argument.
        * modules/fts (Depends-on): Add d-type.  Alphabetize.
        Thanks to Miklos Szeredi for his tenacity and for the initial
        bug report about "find" failing on a FUSE-based file system.

        * lib/fts.c (fts_open): Use consistent indentation.

2006-10-12  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Renamed from
        gl_USE_SYSTEM_EXTENSIONS, to fix a coreutils bootstrap failure
        reported by Jim Meyering.  All uses of cache variables renamed
        to match Autoconf's.
        (gl_USE_SYSTEM_EXTENSIONS): New macro, which simply requires
        the other one.

        * m4/rename-dest-slash.m4 (gl_FUNC_RENAME_TRAILING_DEST_SLASH):
        Fix misspelling in diagnostic.

2006-10-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mkdir-p.c (HAVE_FCHMOD): Define to false if not already
        defined.  Problem reported by Matthew Woehlke.

        * lib/inttypes_.h (_LONG_LONG_FORMAT_PREFIX): New macro.
        Add support for Tandem NonStop R series.
        (_PRI64_PREFIX, _PRIu64_PREFIX, _SCN64_PREFIX, _SCNu64_PREFIX):
        Use new macro.

        * lib/rename-dest-slash.c: Include stdbool.h but not string.h.
        (has_trailing_slash): Omit size arg; all callers changed.
        Omit 'inline', since it doesn't help performance and we'd
        need to configure it.
        Don't count //, ///, etc. as having a trailing slash.
        As a side effect, this removes a C99ism reported by Matthew Woehlke.
        (rpl_rename_dest_slash): On failure, use rename's errno rather
        than (in some cases) an incorrect or junk errno.
        Simplify code by removing need to compute length; this does
        cause it to make two passes instead of one over the file name,
        but it's worth it.

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Undo previous
        change, since Autoconf's version may no longer be appropriate now
        that we are using CVS Autoconf's version.  Add support for Tandem.

            Bruno Haible  <bruno@clisp.org>

        * lib/allocsa.h (sa_alignment_longlong, sa_alignment_max): Test

        * m4/allocsa.m4 (gl_ALLOCSA): Invoke AC_TYPE_LONG_LONG_INT instead of
        gl_AC_TYPE_LONG_LONG.

        * lib/printf-args.h (arg_type, argument): Test HAVE_LONG_LONG_INT

        gl_AC_TYPE_LONG_LONG.

        * lib/c-ctype.h: Don't define the macros if NO_C_CTYPE_MACROS is
        defined. Undefine the macros before defining them, to avoid gcc
        warnings.
        * lib/c-ctype.c: Include config.h. Don't undefine the macros; instead,
        define NO_C_CTYPE_MACROS early.

2006-10-10  Bruno Haible  <bruno@clisp.org>

        Make it possible to #define set_program_name to an alias.
        * lib/progname.c: Don't undefine set_program_name; instead, undefine
        ENABLE_RELOCATABLE early.

2006-10-10  Paul Eggert  <eggert@cs.ucla.edu>

        Port to Tandem NSK OSS, which has 64-bit signed int but at most
        32-bit unsigned int.  Problem reported by Matthew Woehlke in:
        http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00062.html
        More generally, don't assume that 64-bit signed int is available
        if unsigned int is, and vice versa.
        * lib/inttypes_.h (_PRIu64_PREFIX, _SCNu64_PREFIX): Depend on
        unsigned symbols, not on their signed counterparts.
        * lib/stdint_.h (uint64_t, uint_least64_t, uint_fast64_t, uintmax_t):
        (UINT64_MAX, UINT_LEAST64_MAX, UINT_FAST64_MAX, UINTMAX_MAX):
        (UINT64_C, UINTMAX_C):
        Likewise.
        * lib/strtoimax.c (strtoll): Depend on signed symbols, not their
        unsigned counterparts.
        (Have_long_long, Unsigned): New macros.
        (Int): Renamed from INT.
        (strtoimax): Use the new macros.
        * m4/stdint.m4 (gl_STDINT_H): Require AC_TYPE_UNSIGNED_LONG_LONG_INT
        and substitute HAVE_UNSIGNED_LONG_LONG_INT.
        * modules/inttypes (inttypes.h): Substitute
        HAVE_UNSIGNED_LONG_LONG_INT.
        * modules/stdint (stdint.h): Likewise.
        (Files): Add m4/ulonglong.m4.

        for NetBSD.  Problem reported by Bruno Haible.

2006-10-09  Jim Meyering  <jim@meyering.net>

        * lib/lchown.c: Include <sys/stat.h> before "stat-macros.h".
        Patch from Bruno Haible.

2006-10-09  Jim Meyering  <jim@meyering.net>

        * lib/fts-cycle.c (leave_dir): When "leaving" a top level directory due
        to FTS_SKIP, don't copy the parent's uninitialized dev/ino values.
        Trigger with e.g., mkdir d && valgrind ./chmod u+rwx d d

2006-10-08  Paul Eggert  <eggert@cs.ucla.edu>

        Don't include <config.h> twice; this doesn't work in some cases,
        e.g., when config.h has "#define intmax_t long long int" and
        we include <config.h>, <inttypes.h>, <config.h> in that order.

        * lib/strftime.c: Include fprintftime.h if FPRINTFTIME is defined.
        * lib/xstrtoimax.c: Remove copyright notice since it's short tnow.
        Don't include config.h or xstrtol.h.  Define STRTOL_T_MINIMUM
        and STRTOL_T_MAXIMUM unconditionally, since we now assume gnulib
        inttypes.h.
        * lib/xstrtoumax.c: Likewise.
        * lib/xstrtol.c: Include config.h and xstrtol.h after defining

        (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [! defined STRTOL_T_MINIMUM]:
        Remove; no longer needed now that we assume gnulib inttypes.h.

        Work around bug in Solaris 10 /proc file system:
        /proc/self/fd/NNN/.. isn't the parent directory of
        the directory whose file descriptor is NNN.  This needs to
        be worked around at run time, not compile time, since a
        program might be built on Solaris 8, where things work, and
        run on Solaris 10.
        * lib/openat-priv.h (BUILD_PROC_NAME): Remove.  All callers changed

        getaddrinfo.

        Problem reported by Nelson H. F. Beebe.
        * lib/getpass.c: Likewise, except for HAVE_DECL___FSETLOCKING instead

        declaration.

2006-09-27  Jim Meyering  <jim@meyering.net>

        This file could end up with a definition for a function
        named __strndup, rather than rpl_strndup on a system with
        incomplete weak_alias support.
        * lib/strndup.c (strndup): Rename from __strndup.
        Remove #defines that used to map __strndup to strndup.
        Don't use K&R prototypes.
        Remove LIBC-related code, since this file is not sync'd with glibc.
        * lib/strndup.h: Revamp, accordingly.
        * m4/strndup.m4: Modernize.

2006-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_string_reconstruct): Handle
        offset < pstr->valid_raw_len && pstr->offsets_needed case.
        Ensure no bytes read before raw_mbs array.  Pass a saved copy of

        now requires it.
        (gl_PREREQ_REGEX): Don't check for locale.h any more, since

        Prefer "yes" to mean a good thing rather than a bad.
        Don't put "#define mkstemp" in config.h, as this might interfere
        with standard system headers that "#define mkstemp mkstemp64".

        * modules/mkstemp (Depends-on): Add extensions, so that
        mkstemp is visible on some platforms.
        (Makefile.am): Add mkstemp.h to EXTRA_DIST.

        #define mkstemp.
        * lib/mkstemp.c: Revamp to put the !_LIBC code together.
        Include "mkstemp.h".
        Make the _LIBC code resemble glibc original more,

        * lib/mkstemp-safer.c: Include "mkstemp.h" instead of <stdlib.h>.
        (mkstemp): Remove, since mkstemp.h does this for us.
        * lib/stdlib--.h: Include mkstemp.h.

        already-created areas.  Use a subprocess if necessary.  New arg
        WD; all users changed.  MAKE_DIR function should now return 1
        if it creates a directory that is not readable.  Return -2 if

        dgettext.

2006-09-12  Jim Meyering  <jim@meyering.net>

        * lib/nanosleep.c: Include <sys/types.h> before sys/select.h, to avoid

        Reported by Nelson H. F. Beebe.

2006-09-10  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp.h: Likewise

2006-09-10  Bruno Haible  <bruno@clisp.org>

        * modules/mkdtemp (Files): Remove m4/ulonglong.m4, m4/stdint_h.m4,

2006-09-09  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp.h (struct argp): Document the N_("..") "\v" N_("..")
        convention.  Text proposed by Bruno Haible.
        (struct argp_option): Document the use of N_() wrappers.

        * lib/argp-help.c (argp_doc): Split the untranslated doc string on
        '\v', and translate the two parts separately, instead of feeding
        the whole string to gettext.  This allows to exclude
        '\v' from the strings visible to the translator by writing doc
        strings as N_("..") "\v" N_("..").

2006-09-09  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Undo latest change; the bug was fixed.

2006-09-09  Bruno Haible  <bruno@clisp.org>

        2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>
        Add year_2050_test to catch glibc bug 2821

        2006-08-15  Paul Eggert  <eggert@cs.ucla.edu>
        Prefer #ifdef to #if.

        2006-04-02  Paul Eggert  <eggert@cs.ucla.edu>
        Return from 'main' instead of calling 'exit'.

        * lib/mktime.c (guess_time_tm): Fix bug where mktime
        returned the maximum time_t value rather than (time_t) -1.
        Problem originally reported by William Bardwell
        <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.

        * lib/isapipe.h (HAVE_FIFO_PIPES) [!defined HAVE_FIFO_PIPES]:
        Moved to here ...
        * lib/isapipe.c (HAVE_FIFO_PIPES) [!defined HAVE_FIFO_PIPES]:
        ... from here.

2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Temporarily comment out mktime.c until glibc bug
        2821 is fixed.

2006-09-08  Jim Meyering  <jim@meyering.net>

        Don't make generated files read-only.  That would bother too many
        people.  However, do retain the ability to work when targets are
        read-only: remove the destination and temporary files before writing
        them (when generated via sed or echo), or by using the -f option for
        both cp and mv commands.  Suggestion to use -f from Paul Eggert.

2006-08-31  Paul Eggert  <eggert@cs.ucla.edu>

2006-08-18  Jim Meyering  <jim@meyering.net>

        * m4/gethrxtime.m4 (gl_PREREQ_GETHRXTIME): Also check for
        CLOCK_REALTIME, since gethrxtime may revert to using clock_gettime via

        failed to link due to unresolved clock_gettime on a linux-2.4.x system.

2006-08-18  Bruno Haible  <bruno@clisp.org>

        * modules/bison-i18n: New file.

        Update from coreutils.

        * lib/__fpending.h: Add copyright notice.
        * lib/fprintftime.h: Likewise.

        * lib/at-func.c: New file, with the logic of all emulated at-functions.
        * lib/openat-priv.h: Include <errno.h> and define ENOSYS,
        in support of the EXPECTED_ERRNO macro.
        * lib/openat.c (fstatat, unlinkat, fchownat): Remove function
        definitions.  Instead, define the appropriate symbols and include
        "at-func.c".
        * lib/mkdirat.c (mkdirat): Likewise.

        (ENOSYS): Remove definition.
        * lib/openat.c: Don't include <errno.h>, now that "openat-priv.h" does

        2006-01-17  Jim Meyering  <jim@meyering.net>

        Rewrite fts.c not to change the current working directory,
        by using openat, fstatat, fdopendir, etc..

        * lib/fts.c [! _LIBC]: Include "openat.h" and "unistd--.h".
        (HAVE_OPENAT_SUPPORT): Define.
        [_LIBC] (fchdir): Don't undef or define; no longer used.
        (FCHDIR): Define in terms of cwd_advance_fd rather than fchdir.
        Now, this `function' always succeeds, and consumes its file descriptor
        parameter -- so callers must not close such FDs.  Update callers.
        (diropen_fd, opendirat, cwd_advance_fd): New functions.
        (diropen): Add parameter, SP.  Adjust all callers.
        Implement using diropen_fd, rather than open.
        (fts_open): Initialize new member, fts_cwd_fd.
        Remove fts_rft-setting code.
        (fts_close): Close fts_cwd_fd, if necessary.
        (__opendir2): Define in terms of opendir or opendirat,
        depending on whether the FST_NOCHDIR flag is set.
        (fts_build): Since fts_safe_changedir consumes its FD, and since
        this code must do `closedir(dirp)', dup the dirfd(dirp) argument,
        and close the dup'd file descriptor upon failure.
        (fts_stat): Use fstatat(...AT_SYMLINK_NOFOLLOW) in place of lstat.
        (fts_safe_changedir): Tweak semantics to reflect that this function
        now calls cwd_advance_fd and hence consumes its FD argument.
        * lib/fts_.h [struct FTS] (fts_cwd_fd): New member.
        [struct FTS] (fts_rft): Remove now-unused member.
        [struct FTS] (fts_cycle.state): Improve comment.

        * lib/openat.c (openat_needs_fchdir): New function.
        * lib/openat.h (openat_needs_fchdir): Declare it.

        * modules/tmpdir (License): Change to LGPL.

2006-08-15  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_all_modules, func_verify_module): COPYING is not a
        module.

2006-08-14  Simon Josefsson  <jas@extundo.com>

        * config/srclist.txt: Add gnupload.

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        Change copyright notice from LGPL 2 to GPL 2, since that's the

        * tests/test-stdint.c: Likewise.
        * tests/test-tls.c: Likewise.

        notice if "--version" is specified.
        * modules/COPYING: New file.
        * tests/test-getaddrinfo.c: Add copyright notice.

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        Add copyright notices to long-enough files that lack them, since
        otherwise the files aren't clearly free.  Use the same notice that

        was Solaris 1.1A.  Remove space before B in Solaris 1.1.1B.
        Mention SunOS 5.11.  Mention that everything before SunOS 5.7
        is now obsolete, and give a pointer to the Sun list.
        Add copyright notice.

2006-08-14  Paul Eggert  <eggert@cs.ucla.edu>

        remove, these originate in gnulib now.

2006-08-11  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * doc/Makefile (standards.info standards.html standards.dvi):
        Also depend on make-stds.texi.

2006-08-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/pipe-safer.c (pipe_safer): Fix misspelling: HAVE_FUNC_PIPE ->
        HAVE_PIPE.  Fix a file descriptor leak when fd_safer fails.

        * lib/regex_internal.c (re_string_skip_chars): Don't assume WEOF fits
        in wchar_t.  Problem reported by Eric Blake.

        * lib/snprintf.c (snprintf): memcpy LEN bytes, not SIZE - 1, when
        LEN is smaller than SIZE.  Suggested by Bruno Haible.
        Also, help the compiler to keep LEN in a register.

2006-08-11  Eric Blake  <ebb9@byu.net>

        * users.txt: Sort.  Add tar.

2006-08-11  Bruno Haible  <bruno@clisp.org>

        * lib/snprintf.c: Include <errno.h> and <limits.h>.
        (EOVERFLOW): Define if the system does not.
        Do not include "minmax.h"; it wasn't used.
        (snprintf): Don't assume size_t promotes to an unsigned type.
        Fix bug when generated string was too long for the buffer: the
        buffer's contents are supposed to be the initial prefix of the
        output.  Don't assume vasnprintf returns EOVERFLOW if the size
        exceeds INT_MAX; do the check ourselves.

        Import the following changes from libc:

        2006-06-02  Jakub Jelinek  <jakub@redhat.com>

        * lib/posix/regex_internal.c (re_string_skip_chars): If no character
        has been converted at all, set *last_wc to WEOF.  If mbrtowc failed,
        set wc to the byte which couldn't be converted.
        (re_string_reconstruct): Don't clear valid_raw_len before calling
        re_string_skip_chars.  If wc is WEOF after re_string_skip_chars, set
        tip_context using re_string_context_at.

        2006-05-02  Ulrich Drepper  <drepper@redhat.com>

        * lib/posix/regex.h: g++ still cannot handled [restrict].

                aliases list as under WIN32.
                (locale_charset) [CYGWIN]: Try to retrieve the encoding from
                the environment variables. Fall back to GetACP().

        * m4/mkdir-p.m4 (gl_MKDIR_PARENTS): Mention dirchownmod.c,
        dirchownmod.h.  Don't require AC_FUNC_ALLOCA, gl_AFS, gl_CHDIR_SAFER;
        no longer needed.  Require gl_FUNC_LCHOWN, since dirchownmod.c needs
        it.

2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/dirchownmod.c, lib/dirchownmod.h, lib/mkancesdirs.c:

        (make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE,
        MODE_BITS.  Remove options VERBOSE_FMT_STRING, CWD_ERRNO.  All
        callers changed.  Revamp internals significantly, by not
        attempting to create directories that are temporarily more
        permissive than the final results.  Do not attempt to use
        save_cwd/restore_cwd; it isn't worth it for mkdir and install.
        This removes some race conditions, fixes some bugs, and simplifies
        things.  Use new dirchownmod function to do owner and mode changes.
        * lib/mkdir-p.h: Likewise.

        mentioned.
        (mode_adjust): New arg DIR, so that we implement the X op correctly.
        New arg PMODE_BITS, to keep track of which mode bits the user
        mentioned; it treats S_ISUID and S_ISGID speciall.
        All callers changed.
        * lib/modechange.h: Likewise.

2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/mkancesdirs: New module.

        lib/same-inode.h, m4/afs.m4, m4/chdir-safer.m4.
        The chdir-safer and afs files are now orphans; I'll remove them
        unless someone speaks up.
        Add lib/dirchownmod.c, lib/dirchownmod.h.
        (Depends-on): Remove alloca, chown, save-cwd, dirname.
        Add lchown, mkancesdirs.
        (Maintainer): Add self.

2006-07-10  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Like yesterday's change to
        absolute-header.m4.  Also, set ABSOLUTE_STDINT_H to a string
        "no/such/file/stdint.h" when there is no such file, so that
        the resulting C code can be parsed by dodgy compilers.
        Problems reported by Bob Proulx.

        * lib/backupfile.c, dirfd.h, fts.c, getcwd.c, glob.c, glob_.h:

        macros into the GNU _D_EXACT_NAMLEN.
        * lib/savedir.c:  Likewise.
        (savedirstream): Use _D_EXACT_NAMLEN in preference to strlen.

        * gnulib-tool (func_get_filelist): Don't echo m4/onceonly_2_57.m4,
        for the benefit of people using Autoconf 2.60.  If you want to
        support older Autoconf versions you can copy m4/onceonly_2_57.m4
        (or m4/onceonly.m4, if pre-2.57) manually.

        were probably computed using the old broken crc.c?

2006-07-06  Simon Josefsson  <jas@extundo.com>

        * modules/sys_socket (Files): Add m4/sockpfaf.m4 (this module is
        now the canonical place for the M4 file).

        * modules/getaddrinfo (Files): Remove m4/sockpfaf.m4, we get it
        from the sys_socket dependency now.

        with only one argument, for Autoconf 2.60.
        * m4/fileblocks.m4 (gl_PREREQ_FILEBLOCKS): AC_CHECK_DECLS_ONCE may

        * m4/getdate.m4 (gl_GETDATE): Likewise.
        * m4/getusershell.m4 (gl_PREREQ_GETUSERSHELL): Likewise.
        * m4/memcasecmp.m4 (gl_MEMCASECMP): Likewise.

        * m4/xstrtol.m4 (gl_PREREQ_XSTRTOL): Likewise.
        * m4/exclude.m4 (gl_EXCLUDE): Don't require AC_C_INLINE; no longer
        needed.

2006-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/memcasecmp.c: Include <limits.h>.
        (memcasecmp): Don't assume UCHAR_MAX <= INT_MAX.
        * lib/strtod.c (strtod): Don't assume isspace works on negative chars.
        Don't assume isdigit succeeds only on '0' through '9'.

2006-07-05  Eric Blake  <ebb9@byu.net>

        * modules/getaddrinfo (Depends-on): Add snprintf.

2006-07-05  Eric Blake  <ebb9@byu.net>

        * m4/sockpfaf.m4 (gl_SOCKET_FAMILIES): Use gl_HEADER_SYS_SOCKET
        to avoid 'header present but could not be compiled' on cygwin.

2006-07-05  Eric Blake  <ebb9@byu.net>

        * lib/getaddrinfo.h (NI_NUMERICHOST, NI_NUMERICSERV): Define if
        missing from netdb.h.
        * lib/getaddrinfo.c (includes): Include inet_ntop and snprintf.

2006-07-05  Derek R. Price  <derek@ximbiot.com>

        * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Don't require AC_HEADER_STDC;
        no longer needed.
        * m4/exclude.m4 (gl_EXCLUDE): Likewise.

2006-07-05  Derek R. Price  <derek@ximbiot.com>

        * lib/exclude.c (IN_CTYPE_DOMAIN, is_space): Remove; no longer needed.
        All uses of is_space replaced by isspace.
        * lib/exit.h: Don't talk about STDC_HEADERS.
        * lib/fnmatch.c (ISASCII): Remove; no longer needed.  All uses removed.
        (ISPRINT, ISDIGIT, ISALNUM, ISALPHA, ISCNTRL, ISLOWER, ISPUNCT):
        (ISSPACE, ISUPPER, ISXDIGIT): Remove; no longer needed.  All uses
        replaced by isprint etc.
        * lib/getdate.y (IN_CTYPE_DOMAIN, ISSPACE, ISALPHA, ISLOWER): Likewise.

2006-07-05  Bruno Haible  <bruno@clisp.org>

        * m4/strndup.m4 (gl_FUNC_STRNDUP): When cross-compiling, check whether
        the function exists, before testing against AIX.
        Reported by Martin Lambers <marlam@marlam.de>.

2006-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/cycle-check (lib_SOURCES): Add same-inode.h.
        From Mark D. Baushke.

2006-07-04  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/absolute-header.m4 (gl_ABSOLUTE_HEADER): Prepend three slashes
        to the absolute name, not just one, to bypass Sun C 5.8's
        "warning: #include of /usr/include/... may be non-portable".

2006-07-04  Eric Blake  <ebb9@byu.net>

        * modules/dirname-tests: New test module.
        * tests/test-dirname.c: New file, replacing dirname.c
        TEST_DIRNAME section that was recently deleted.

2006-07-04  Bruno Haible  <bruno@clisp.org>

        Assume ANSI C header files and <ctype.h> functions.
        * lib/mbswidth.c (IN_CTYPE_DOMAIN, ISPRINT, ISCNTRL): Remove macros.
        (mbsnwidth): Use isprint, iscntrl instead.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.
        * MODULES.html.sh: Add xstrtold.
        * modules/xstrtold: New file.
        * modules/cycle-check (Files): Add lib/same-inode.h.
        * modules/dirname (Files): Add m4/double-slash-root.m4.
        * modules/getcwd (Files): Add m4/getcwd-abort-bug.m4.
        * modules/mkdir-p (Files): Add lib/same-inode.h.
        * modules/same (Files): Add lib/same-inode.h.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/absolute-header.m4: Renamed from full-header-path.m4.
        This is to keep the terminology clean; POSIX talks about
        "absolute pathnames", not "full pathnames", but the GNU
        Coding Standards say to use "path" for something else;
        so use "absolute" to keep both sides happy.
        (gl_ABSOLUTE_HEADER): Renamed from gl_FULL_HEADER_PATH.
        Set gl_absolute_header, not gl_full_header_path.
        Set gl_cv_absolute_<header>, not gl_full_path_<header>.
        Define ABSOLUTE_<HEADER>, not FULL_PATH_<HEADER>.
        All uses changed.

        Merge from coreutils.

        2006-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/c-strtod.m4 (gl_C_STRTOLD): Add c-strtod.c to LIBSOURCES.
        Require gl_USE_SYSTEM_EXTENSIONS, not gl_C_STRTOD, since we don't
        want to require the building of c-strtod.o.
        * m4/lib-check.m4 (cu_LIB_CHECK): Remove SEQ_LIBM, since seq no longer
        needs -lm directly.
        * m4/xstrtod.m4 (gl_XSTRTOLD): New macro.

        2006-06-19  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Prefer binutils's
        --as-needed option if available.  Problem reported by Albert Chin in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00114.html>.
        However, use -Wl,--as-needed, not bare --as-needed, since HP-UX 11.11
        cc merely issues a bunch of annoying warnings for --as-needed
        (this problem was reported by Bob Proulx).  Also, try linking with
        -lm to detect a bug in binutils 2.16 (this problem was reported
        by Ralf Wildenhues).

        2006-06-18  Jim Meyering  <jim@meyering.net>

        Test for a bug that causes glibc's getcwd to suffer a failed assertion.
        * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): New file and
        macro.
        * m4/getcwd.m4 (gl_FUNC_GETCWD): If we detect support for getcwd_null,
        also check for glibc-2.4's abort-inducing bug.

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Fix typo.
        Low-probability clean-up should be to use rmdir to get rid of
        the just-created directory, not unlink.

        * m4/ftruncate.m4 (gl_FUNC_FTRUNCATE): If ftruncate is missing, make
        configure fail, and request a bug report to inform us about it.
        Add a comment that, barring reports to the contrary, in 2007 we'll
        assume ftruncate is universally available.

        2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/filemode.m4 (gl_FILEMODE): Check for strmode declaration.

        2006-03-12  Jim Meyering  <jim@meyering.net>

        * m4/chdir-safer.m4 (gl_CHDIR_SAFER): Add same-inode.h to the list.
        * m4/cycle-check.m4 (gl_CYCLE_CHECK): Likewise.
        * m4/same.m4 (gl_SAME): Likewise.
        * m4/root-dev-ino.m4 (gl_ROOT_DEV_INO): Likewise.

        2006-03-11  Eric Blake  <ebb9@byu.net>

        * m4/double-slash-root.m4: New file, provides gl_DOUBLE_SLASH_ROOT.
        * m4/dirname.m4 (gl_DIRNAME): Use gl_DOUBLE_SLASH_ROOT.
        * m4/dos.m4 (FILE_SYSTEM_PREFIX_LEN): Move from here to dirname.h.
        (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): New define.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h: Include <sys/types.h> after @FULL_PATH_STDINT_H@, for
        MacOS X 10.4.6.  Don't mention <sys/int_types.h>.  Problems
        reported by Mark D. Baushke, one in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00015.html>.

        Merge from coreutils.

        * lib/.cppi-disable: Add stdint_.h.
        * lib/.cvsignore: Add stdint.h.

        2006-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xstrtod.c (XSTRTOD, DOUBLE): New macros, so that we can support
        both double and long double versions.
        (XSTRTOD): Renamed from xstrtod.  Use DOUBLE internally.
        * lib/xstrtold.c: New file.
        * lib/xstrtod.h (xstrtold): New decl.

        2006-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/filemode.c (setst): Remove.
        (strmode): Rewrite to avoid setst.  This makes the code shorter,
        (arguably) clearer, and the generated code is a bit smaller on my
        Debian GNU/Linux stable x86 host.

        2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/filemode.c: Include "filemode.h" first, to test the interface.
        Assume that filemode.h includes sys/types.h and sys/stat.h.
        (HAVE_ST_DM_MODE): New macro, moved here from ls.c.
        (ftypelet): Reorder to put common cases first, for efficiency.
        Add 'P', 'w'.  Remove 'M', since it's now the caller's responsibility
        to do 'M'.
        (strmode): Renamed from mode_string, and now stores 12 bytes instead
        of 10, for compatibility with FreeBSD.  All callers changed.
        (filemodestring): Now stores 12 bytes instead of 10, and sets file
        types that can't be deduced solely from st_mode.  First arg is now a
        const pointer.
        * lib/filemode.h (HAVE_DECL_STRMODE): Include <string.h> for strmode.
        (strmode): Renamed from mode_string.
        (filemodestring): New decl.
        * lib/stat-macros.h: Don't undef S_ISDOOR, since it's never buggy.
        (S_ISDOOR): Don't bother with S_IFDOOR, since that code is never
        needed.
        (S_ISPORT, S_ISWHT): New macros, if not already defined.

        2006-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fsusage.c: Don't include <inttypes.h> or <stdint.h>, since
        fsusage.h now does that.  Include fsusage.h first, to test interface.
        Prefer statvfs if it works, since it's blessed by POSIX.  Attempt
        at most one method (the old code could have generated decls that
        didn't conform to C89, not that this was ever exercised).
        * lib/fsusage.h: Include <inttypes.h> and <stdint.h> if they exist.

        2006-03-19  Jim Meyering  <jim@meyering.net>

        Work even in a chroot where d_ino values for entries in "/"
        don't match the stat.st_ino values for the same names.
        * lib/getcwd.c (__getcwd): When no d_ino value matches the target inode
        number, iterate through all entries again, using lstat instead.
        Reported by Kenshi Muto in http://bugs.debian.org/355810, and by
        Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656.

        * lib/getcwd.c (__getcwd): Clarify a comment.
        Use memcpy in place of a call to strcpy.

        2006-03-12  Jim Meyering  <jim@meyering.net>

        * lib/fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair
        matches that of the current directory (which we're about to chdir ".."
        out of), then save the dev-ino of the parent, instead.

        * lib/same-inode.h (SAME_INODE): New file/macro.
        * lib/chdir-safer.c (SAME_INODE): Remove definition.
        Include "same-inode.h", instead.
        * lib/same.c: Likewise.
        * lib/cycle-check.h: Include "same-inode.h".
        (CYCLE_CHECK_REFLECT_CHDIR_UP): Define.
        * lib/cycle-check.c (SAME_INODE): Remove definition.
        * lib/root-dev-ino.h: Include "same-inode.h".

        2006-03-11  Eric Blake  <ebb9@byu.net>

        * lib/same.c (same_name): s/base_name/last_component/
        * lib/backupfile.c (check_extension, numbered_backup): Likewise.
        * lib/filenamecat.c (file_name_concat): Likewise.

        2006-03-11  Eric Blake  <ebb9@byu.net>,
                    Paul Eggert  <eggert@cs.ucla.edu>

        * lib/dirname.h (FILE_SYSTEM_PREFIX_LEN): Move here from dos.m4.
        [FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't treat 1: as a
        drive prefix.
        (IS_ABSOLUTE_FILE_NAME): Treat all drive letters as absolute on
        platforms like cygwin with FILE_SYSTEM_DRIVE_PREFIX_IS_ABSOLUTE.
        (last_component): New method.
        * lib/dirname.c (dir_len): Determine when drive letters need a
        subsequent slash.  Preserve // when it is special.
        (dir_name): Don't append dot when drive letter is absolute.
        [TEST_DIRNAME]: Move into a full-blown gnulib test.
        * lib/basename.c (base_name): New semantics - malloc the result.
        Preserve // when it is special.  Preserve relative files that look
        like drive letters.
        (base_len): Preserve // when it is special.
        (last_component): New method, similar to old base_name semantics.
        * lib/stripslash.c (strip_trailing_slashes): Use last_component, not
        base_name.  Strip redundant slashes from ///.

2006-07-03  Jim Meyering  <jim@meyering.net>

        * lib/cycle-check.h (CYCLE_CHECK_REFLECT_CHDIR_UP): Abort if this
        macro is used before the first cycle_check call.

2006-07-03  Eric Blake  <ebb9@byu.net>

        * modules/dirname (Depends-on): Add xstrndup.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdint.m4 (gl_STDINT_H): Use more-mnemonic identifiers for
        test cases, so that config.log is a bit easier to follow.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h (intmax_t, uintmax_t): Prefer long to long long if
        both are 64 bits, since this seems to be the tradition, and this
        prevents gcc -Wformat from warning about usages with PRIuMAX.  If
        we ever run into a host that prefers long long to long in this
        case, we'll need another configure-time test.  Problem reported by
        Jim Meyering.

2006-07-02  Eric Blake  <ebb9@byu.net>

        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Simplify by using AC_CHECK_DECLS.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/inttypes (Depends-on): No longer depends on stdint.
        * modules/stdint (Description): Say more about assumptions.
        Say that the fast types might differ.  Say macros are used.
        (Files): Remove m4/size_max.m4, m4/wchar_t.m4.  Add m4/longlong.m4.
        (Makefile.am): Revise list of substituted symbols to match
        new stdint.m4.
        * modules/stdint-tests (Files): Add m4/wchar_t.m4, m4/wint_t.m4.
        (configure.ac): Add gt_TYPE_WCHAR_T, gt_TYPE_WINT_T.
        * tests/test-stdint.c (verify_same_types)
        [! (__GNUC__ >= 2 && DO_PEDANTIC)]: Put in a decl, so that
        the code conforms to C99/C89.
        Test for WCHAR_MIN and WCHAR_MAX only if HAVE_WCHAR_T.
        Test for WINT_MIN and WINT_MAX only if HAVE_WINT_T.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Backport from Autoconf 2.60,
        but fix a bug, by requiring at least 64 bits.
        * m4/ulonglong.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
        * m4/longlong.m4 (gl_AC_TYPE_LONG_LONG): Now just call
        AC_TYPE_LONG_LONG_INT.  This macro is obsolete and will go soon.
        * m4/ulonglong.m4 (gl_AC_TYPE_UNSIGNED_LONG_LONG): Likewise.

        * m4/stdint.m4 (gl_STDINT_H): Rewrite to accommodate stdint_.h
        changes.  Make 2.59 a prerequisite.  Check and substitute for
        HAVE_LONG_LONG_INT.  Rely on Autoconf to check for stdint.h and
        inttypes.h.  Do not use special include files; just use the
        defaults.  Check for sys/inttypes.h and sys/bitypes.h in the usual
        way now.  Remove no-longer-needed tests for HAVE_LONG_64BIT,
        HAVE_LONG_LONG_64BIT, int8_t, int16_t, int32_t, int64_t, uint8_t,
        uint16_t, uint32_t uint64_t, int_least8_t, int_least16_t,
        int_least32_t, int_least64_t, uint_least8_t, uint_least16_t,
        uint_least32_t, uint_least64_t, int_fast8_t, int_fast16_t,
        int_fast32_t, int_fast64_t, uint_fast8_t uint_fast16_t,
        uint_fast32_t, uint_fast64_t, intptr_t, uintptr_t, intmax_t,
        uintmax_t, INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX,

        INT64_MAX, UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX,
        UINT_LEAST8_MAX, INT_LEAST16_MIN, INT_LEAST16_MAX,
        UINT_LEAST16_MAX, INT_LEAST32_MIN, INT_LEAST32_MAX,
        UINT_LEAST32_MAX, INT_LEAST64_MIN, INT_LEAST64_MAX,
        UINT_LEAST64_MAX, INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX,
        INT_FAST16_MIN, INT_FAST16_MAX, UINT_FAST16_MAX, INT_FAST32_MIN,
        INT_FAST32_MAX, UINT_FAST32_MAX, INT_FAST64_MIN, INT_FAST64_MAX,
        UINT_FAST64_MAX, INTPTR_MIN, INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN,
        INTMAX_MAX, UINTMAX_MAX, PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN,
        SIG_ATOMIC_MAX, SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN,
        WINT_MAX.  Check for C99 conformance more strictly, by detecting
        bugs in glibc 2.4, Solaris 10, and OpenBSD 3.9.  On the other hand do
        not check for things that C99 does not require, e.g., int8_t.  If
        a test isn't needed unless <stdint.h> isn't working, and is
        unlikely to be needed for any other reason, then don't do it
        unless <stdint.h> isn't working.  Do not check for ptrdiff_t or
        size_t, since we assume C89 freestanding at least.  Do not check
        for sig_atomic_t, wchar_t, or wint_t, since the code now does
        the right thing even if the types are not defined.  Instead use:
        (gl_STDINT_TYPE_PROPERTIES): New macro.
        (gl_HEADER_STDINT_H, gl_HEADER_INTTYPES_H): Remove.  Don't bother
        testing whether <sys/types.h> clashes, as Autoconf does this for
        us now.  All uses removed.
        (gl_STDINT_CHECK_TYPES, gl_STDINT_MISSING_BOUND):
        (gl_STDINT_MISSING_BOUNDS, gl_STDINT_MISSING_BOUNDS2):
        (gl_CHECK_TYPE_SAME):
        Remove; no longer needed.
        (gl_STDINT_BITSIZEOF): Don't bother to check whether the type
        exists, since we'll return 0 anyway in that case.
        (gl_INTEGER_TYPE_SUFFIX, gl_STDINT_INCLUDES): New macros.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdint_.h (_GL_STDINT_H): Renamed from _STDINT_H, to avoid
        possible collision with system files.
        (<stdio.h>, <time.h>, <wchar.h>) [defined __cplusplus && ! defined
        __STDC_CONSTANT_MACROS)]: Do not include, since we don't need
        WCHAR_MIN and WCHAR_MAX in this case.
        (<stddef.h>): Do not include; no longer needed.
        (<sys/types.h>): Include if @HAVE_SYS_TYPES_H@, not if
        (defined(__OpenBSD__) || defined(__bsdi__) || defined(__sgi)).
        (<sys/inttypes.h>): Include if @HAVE_SYS_INTTYPES_H@ &&
        !@HAVE_INTTYPES_H@, not if (defined(__FreeBSD__)
        && (__FreeBSD__ >= 3) && (__FreeBSD__ <= 4)).
        (__STDINT_H__) [@HAVE_STDINT_H@ && defined __sgi && ! defined
        __c99]: Define, to work around IRIX <stdint.h> incompatibility.
        (@FULL_PATH_STDINT_H@) [!(defined(__sgi) && @HAVE_INTTYPES_H@ &&
        !defined(__c99))]: Include in this case too, since it's harmless
        now.
        (<inttypes.h>) [@HAVE_INTTYPES_H@]: Include, since it's no longer
        dangerous to do so.
        (@FULL_PATH_INTTYPES_H@) [(defined(__hpux) || defined(_AIX)) &&
        @HAVE_INTTYPES_H@]: Do not include, since we now include <inttypes.h>.
        (_STDINT_MIN, _STDINT_MAX): New macros.
        (int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t):
        (uint64_t, int_least8_t, uint_least8_t, int_least16_t):
        (uint_least16_t, int_least32_t, uint_least32_t, int_least64_t):
        (uint_least64_t, int_fast8_t, uint_fast8_t, int_fast16_t):
        (uint_fast16_t, int_fast32_t, uint_fast32_t, int_fast64_t):
        (uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t): Now
        macros, not typedefs; this simplifies things quite a bit.
        Use long int for all types narrower than int64_t.
        (intmax_t, uintmax_t, INTMAX_C, UINTMAX_C):
        Define in terms of long long int or int64_t or long int,
        not int64_t or int32_t.  This saves some compile-time testing.
        (INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX):
        (INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX):
        (UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX, UINT_LEAST8_MAX):
        (INT_LEAST16_MIN, INT_LEAST16_MAX, UINT_LEAST16_MAX):
        (INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX):
        (INT_LEAST64_MIN, INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST8_MIN):
        (INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX):
        (UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX):
        (INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX, INTPTR_MIN):
        (INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX):
        (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
        (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
        undef any previous version and define our own version, for
        simplicity and consistency with the new macros for types.
        (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
        (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
        Simplify definitions by using _STDINT_MIN and _STDINT_MAX
        where appropriate.  Rely on new symbols @PTRDIFF_T_SUFFIX@,
        @SIG_ATOMIC_T_SUFFIX@, @SIZE_T_SUFFIX@, @WCHAR_T_SUFFIX@,
        @WINT_T_SUFFIX@ to keep things simple here.
        (UINT8_C, UINT16_C, UINT32_C, INT64_C, UINT64_C):
        Simplify by assuming typical 8/16/32/64 host, since we're
        already doing that elsewhere anyway.
        Use (LONG_MAX >> 31 >> 31 == 1) rather than @HAVE_LONG_64BIT@,
        and assume long long int is 64 bits if available.  This
        speeds up 'configure'.

2006-07-01  Eric Blake  <ebb9@byu.net>

        * m4/stdarg.m4 (gl_STDARG_H): Use proper AH_VERBATIM.

2006-06-28  Simon Josefsson  <jas@extundo.com>

        * lib/getaddrinfo.c: Try to load ws2_32.dll on Windows, to find the
        functions there.  It will succeed on Windows XP, but on Windows
        2000 and (presumably) earlier, it will fail, and use the internal
        re-implementation.
        (use_win32_p): New function.
        (getaddrinfo): Use strtoul on servname, to support numeric ports.
        Support AI_NUMERICSERV to disable getservbyname.
        (getnameinfo): New function, only supports
        NI_NUMERICHOST|NI_NUMERICSERV for now.

        * lib/getaddrinfo.h: Test and check for AI_* flags separately, MinGW
        only have some of them.  Add AI_NUMERICSERV.  Add prototype for
        getnameinfo.

        * lib/glob.c (collated_compare): Remove 'const' uses that weren't
        needed.  Some compiler complained about some of them.  Problem reported
        by Larry Jones in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00172.html>.

2006-06-21  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Don't define WINVER.  Look for gethostbyname in
        -lws2_32 too.  Fixes getaddrinfo on Windows 2000, with the price
        of using the (limited) gnulib implementation on Windows XP.

2006-06-21  Simon Josefsson  <jas@extundo.com>

        * lib/read-file.c (fread_file): Start with buffer allocation of
        0 bytes rather than 1 byte; this simplifies the code.
        Don't invoke feof; it's not needed.  Refactor to avoid duplicate
        code to free buffer and save/restore errno.
        (internal_read_file): Remove unused local.

2006-03-25  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * m4/argz.m4 (gl_FUNC_ARGZ): If we define `error_t', also define
        `__error_t_defined', so argp.h will not typedef the former.

2006-03-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Don't insist on REG_SYNTAX_POSIX_EGREP,
        REG_SYNTAX_EMACS, and REG_IGNORE_CASE.  Settle for the traditional
        glibc names.  Even if glibc is changed to conform to POSIX, the
        traditional names will be available anyway, since regex depends on
        the extensions module.  Also, fix a longstanding typo in the
        implementation of Spencer ERE test #75 from grep 2.3.  Problems
        reported by Emanuele Giaquinta.  Also, change sense of cached
        variable, so that the message makes sense.

2006-03-24  Simon Josefsson  <jas@extundo.com>

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Don't check for off_t, since the code
        no longer needs it.  Instead, check that regoff_t is as least
        as wide as ptrdiff_t.

        Don't define _REGEX_WIDE_OFFSETS unless using the included regex,
        so that our regex.h stays compatible with the installed regex.
        This is helpful for installers who configure --without-included-regex.
        Problem reported by Emanuele Giaquinta.

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h (regoff_t) [defined _REGEX_LARGE_OFFSETS]:
        Typedef to long int, not to off_, as POSIX will likely change
        in that direction.

2006-03-15  Eric Blake  <ebb9@byu.net>

        * m4/dirfd.m4 (gl_FUNC_DIRFD): Use AC_REQUIRE for AC_HEADER_DIRENT.

2006-03-13  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-help.c (validate_uparams): Fix typo
        * lib/argp-parse.c (argp_default_options): Consistently begin help
        messages with a lowercase letter.

2006-03-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/time_r.h (asctime_r, ctime_r): Remove.  These functions can
        overrun buffers and shouldn't be used (much as gets shouldn't be
        used).
        * lib/time_r.c (asctime_r, ctime_r): Likewise.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * m4/gc-random.m4: Permit 'no' as variable values and fix warnings,

        * m4/gc-random.m4: Call AC_CANONICAL_HOST and use $host_os instead of

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * lib/gc-gnulib.c (randomize): Don't open files called 'no', they
        signal that configure disabled the device.

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Fix refresh-po, to handle no translated
        languages.

        variable gl_cv_lib_readline, and moving the assignment of
        LIBREADLINE and LTLIBREADLINE outside the COMMANDS-TO-SET-IT.
        From Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

2006-03-07  Simon Josefsson  <jas@extundo.com>

        * m4/unistd_h.m4 (gl_HEADER_UNISTD): Rename, to match modules file.
        Problem reported by Juan Manuel Guerrero.

2006-03-07  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/c-stack.c: Include unistd.h unconditionally, since we now assume

2006-03-03  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de> (tiny change)

        * m4/poll.m4 (gl_FUNC_POLL): If we deem poll(2) unacceptable, use
        our replacement poll.h in any case, to avoid a differing
        declaration from a system header.  Seen on AIX.

2006-03-01  Simon Josefsson  <jas@extundo.com>

        * lib/readline.c: Fix typo, tiny patch from Stepan Kasal

        * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Use gl_HEADER_SYS_SOCKET.
        (gl_GETADDRINFO): Don't use ws2tcpip.h when sys/socket.h is present.

2006-02-14  Simon Josefsson  <jas@extundo.com>

        * modules/maintainer-makefile (Files): Rename.

        * build-aux/GNUmakefile: Rename Makefile.maint to maint.mk
        and (the local) Makefile.cfg to maint-cfg.mk.

        * build-aux/Makefile.maint, build-aux/maint.mk: Renamed the former
        to the latter.

        * modules/maintainer-makefile: New module.

        * build-aux/Makefile.maint: New file, from GNU CoreUtils, although
        severaly stripped to make it possible to build it up from scratch
        with reliable tests.

        * build-aux/GNUmakefile: New file, from GNU CoreUtils with some
        fixes to permit overriding the default actions when configure and
        makefile are not available.

2006-02-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * modules/lstat (Depends-on): Don't depend on xalloc.
        (License): Change from GPL to LGPL, since this is now simply a
        replacement for a libc function.

2006-02-14  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        Eliminate the unwelcome (albeit unlikely) possibility of xmalloc
        failure on deficient systems, and simplify gnulib lgpl dependencies.
        * lib/lstat.c (rpl_lstat): Rewrite to use stat() in place of the
        xmalloc/lstat combination.  Based on a patch from Bruno Haible.

        * lib/xalloc-die.c: Remove unused definition of N_.

2006-02-14  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.
        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Invoke
        AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
        $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need not
        double-quote uses of that variable, to accommodate the rare case in
        which getmntent is available in none of the libraries checked.  This
        happens at least on FreeBSD 5.0.

2006-02-13  Simon Josefsson  <jas@extundo.com>

        * gnulib-tool (Usage): Fix --import, from
        karl@freefriends.org (Karl Berry).

2006-02-13  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-fmtstream.c: Restore another bugfix lost on 2005-12-12

2006-02-07  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-namefrob.h: Restore changes accidentally lost during the
        "autoupdate" on 2005-12-12.

2006-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/closeout (Depends-on): Remove atexit.

2006-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/closeout.c (close_stdout): Don't assume 'bool' converts nonzero
        ints to 0 or 1, as this isn't true for the stdbool.h substitute.

2006-02-05  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Don't #define
        __EXTENSIONS__ if this causes compilation to fail.  Problem
        reported by Nelson H. F. Beebe with Solaris 10 and Sun C 5.7
        c89 -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED.

2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fnmatch.c (L_): Renamed from L, to work around a bug in
        Mac OS X 10.3.9 with GCC 3 reported by Claudio Fontana in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-01/msg00074.html>.
        All uses changed.

2006-01-26  Simon Josefsson  <jas@extundo.com>

        * lib/socket_.h: Set WINVER to 0x0501, to make sure getaddrinfo
        prototype is visible on mingw32.

        * lib/getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set,
        for mingw32.

        * lib/gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for
        mingw32).

2006-01-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/fts.c (diropen): Open with O_NOCTTY | O_NONBLOCK too.  Don't
        attempt to open for write; this always fails, at least on POSIX
        hosts.  This reinstates the 2006-01-09 change, which was
        inadvertently removed.

2006-01-26  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Use "trap 'exit $?' instead of "trap :".
        Reported by Paul Eggert.

2006-01-26  Bruno Haible  <bruno@clisp.org>
            Paul Eggert  <eggert@cs.ucla.edu>

        * lib/stdbool_.h (_Bool)
        [(! (defined __cplusplus || defined __BEOS__)
          && !defined __GNUC__
          && !(defined __HP_cc || defined __xlc__
               || (defined __SUNPRO_C && (__SUNPRO_C < 0x550 || __STDC__ == 1))
               || defined __sgi))]:
        #define to signed char in these cases too; this simplifies
        the code (so that we don't have to worry about HP-UX, AIX, SunPRO,
        etc., separately) and makes it more conservative.

2006-01-25  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Look for getaddrinfo inside ws2tcip.h and
        -lws2_32.  Protect sys/socket.h and netdb.h #include's.  Include
        ws2tcpip.h with WINVER=0x0501.  All for mingw32.

2006-01-25  Sergey Poznyakoff  <gray@gnu.org.ua>

        * lib/argp-namefrob.h: Bugfix. Remove stray #

2006-01-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdbool.m4 (AC_HEADER_STDBOOL): Check for xlc bug if __GCC__ too,
        so that we test the test.
        Check for yet another HP-UX cc bug involving *bool |= bool.

2006-01-25  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (vasnprintf.c): sync lost.

2006-01-25  Jim Meyering  <jim@meyering.net>

        Sync from the stable (b5) branch of coreutils:

        * lib/fts.c (fts_children): Don't let close() clobber errno from
        failed fchdir().

        * lib/fts.c (fts_stat): When following a symlink-to-directory,
        don't necessarily interpret stat-fails+lstat-succeeds as indicating
        a dangling symlink.  That can also happen at least for ELOOP.
        The fix: return FTS_SLNONE only when the stat errno is ENOENT.
        FYI, this bug predates the inclusion of fts.c in coreutils.

        * lib/fts.c (fts_open): Put new maxarglen declaration and uses
        in their own block, so pre-c99 compilers don't object.

        Avoid the double-free (first in fts_read, second in fts_close) that
        would occur when an `active' directory is made inaccessible (e.g.,
        via chmod a-x) during a traversal.
        * lib/fts.c (fts_read): After a failed fchdir, update sp->fts_cur
        before returning.  Reproduce this failure by
        mkdir -p a/b; cd a; chmod a-x . b
        Reported by Stavros Passas.

2006-01-25  Jim Meyering  <jim@meyering.net>

        * lib/fileblocks.c: Remove more useless parentheses.
        * lib/readutmp.h: Likewise.

2006-01-25  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h (_Bool) [IRIX cc]: Define as 'signed char', to avoid
        warnings.
        Reported by Paul Eggert.

2006-01-25  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Use "trap :" instead of "trap -" to get
        rid of a trap command. For Solaris sh.
        Reported by Mark D. Baushke <mdb@gnu.org>.

2006-01-24  Simon Josefsson  <jas@extundo.com>

        * lib/socket_.h (SHUT_WR, SHUT_RDWR): Don't hardcode, suggested by

        Patch by Paul Eggert.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h (_Bool) [__cplusplus]: Don't define if the compiler
        already has it.
        Report and patch by Albert Chin-A-Young  <china@thewrittenword.com> on
        2005-11-26.

        * lib/stdbool_.h (_Bool) [HP-UX cc, AIX cc,xlc]: Define as
        'signed char' to avoid problems with the built-in _Bool type.
        Reported by Paul Eggert on 2005-11-26.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Avoid constructing complicated sed

2006-01-23  Ulrich Drepper  <drepper@redhat.com>

        These changes imported from libc.
        * lib/getopt.c: Use __fxprintf instead of inline stream orientation
        test and two separate function calls.
        * lib/strndup.c (__strndup): Add libc_hidden_def.

2006-01-23  Simon Josefsson  <jas@extundo.com>

        * modules/lock-tests: Use check_PROGRAMS instead of noinst_PROGRAMS.
        Remove the test_*_SOURCES variable: automake infers it by default.
        * modules/tls-tests: Likewise.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        Work around porting bugs reported by Dieter in
        <http://lists.gnu.org/archive/html/bug-bison/2006-01/msg00049.html>.
        * lib/getopt.c (_NOPROTO): Remove; no longer needed.
        Include <stdlib.h> and <unistd.h> in all environments; it's safe now.
        Include "getopt.h" first, to check interface.

        !HAVE_DECL_GETENV.
        * lib/strndup.c [!_LIBC]: Include "strndup.h" to get prototype.
        (__strndup): Revert to K&R-style function dfns, the glibc style.
        * lib/strnlen.c: Don't claim it's taken from glibc; it's not.
        (strnlen, __strnlen): Remove #defines and #undefs; not needed.
        Include strnlen.h first, to get prototype properly.
        (strnlen): Renamed from __strnlen.
        Remove weak alias.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Adjust to reflect glibc reorganization.
        This affects only comments.

2006-01-22  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>  (tiny change)

         * gnulib-tool, build-aux/csharpcomp.sh.in: Do not pass `-q' to mktemp.
         Reported by Bruce Korb <bkorb@gnu.org>.

        temporary buffer for sprintf, take into account the precision also
        for 'd', 'i', 'u', 'o', 'x', 'X'.

        preprocessor mishandles large unsigned values as if they were signed.
        Problem reported by Claudio Fontana in

        Avoid the double-free (first in fts_read, second in fts_close) that
        would occur when an `active' directory is made inaccessible (e.g.,
        via chmod a-x) during a traversal.
        * lib/fts.c (fts_read): After a failed fchdir, update sp->fts_cur
        before returning.  Reproduce this failure by
        mkdir -p a/b; cd a; chmod a-x . b
        Reported by Stavros Passas.

        * lib/chdir-long.c (cdb_free): Don't bother trying to open directory

        * lib/fts.c (diropen): Likewise.
        * lib/save-cwd.c (save_cwd): Likewise.
        * lib/chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
        well, for minor improvements on hosts that lack O_DIRECTORY.
        * lib/chown.c (rpl_chown) [CHOWN_MODIFIES_SYMLINK]:
        Don't try O_WRONLY unless O_RDONLY failed wth EACCES.
        Fall back on chown if open failed with EACCES.

        * lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
        Report an error at compile-time if only a 1-second nominal clock
        resolution is found.

        * lib/lchmod.h: New file.
        * lib/mkdir-p.c: Include lchmod.h, lchown.h.
        (make_dir_parents): Use lchown rather than chown, and
        lchmod rather than chmod.

        * lib/mountlist.c (ME_DUMMY): "none" and "proc" file systems are
        dummies too.  Problem with "none" reported by Bob Proulx.  Problem with
        "proc" reported by n0dalus.

        * lib/mountlist.c: Include <limits.h>.
        (dev_from_mount_options)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
        New function.  It no longer assumes "dev=" has the System V meaning
        on Linux (since it doesn't).  It also parses "dev=" more carefully.
        (read_file_system_list)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
        MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
        dev= in that case.

        * lib/posixtm.h (PDS_PRE_2000): New macro.
        * lib/posixtm.c (year): Arg is now syntax_bits rather than

        that starts with an octal digit.  From Andreas Gruenbacher.

        * lib/openat.c: Include "fcntl--.h" and "unistd--.h", to map open
        and dup to open_safer and dup_safer, respectively.
        (openat_permissive): Fix typo in comment.

        * lib/openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>,
        "gettext.h"; either no longer needed or are guaranteed by openat.h.
        (_): Remove; no longer needed.
        (openat): Renamed from rpl_openat; no need for rpl_openat
        since openat.h renames openat for us.
        Replace most of the body with a call to openat_permissive,
        to avoid duplicate code.
        Port to (probably hypothetical) environments were mode_t is
        wider than int.
        (openat_permissive): Require mode arg, so that we can check
        types better.  Put it just after flags.  Change cwd failure
        indicator from pointer-to-bool to pointer-to-errno-value.
        All callers changed.
        Invoke openat_save_fail and/or openat_restore_fail if
        cwd_errno is null, so that openat can call us.
        (openat_permissive, fdopendir, fstatat, unlinkat):
        Simplify errno handling to avoid some duplicate code,
        as it's OK to set errno on success.
        * lib/openat.h: Revamp code so that function macros depend on
        __OPENAT_PREFIX only, not also on AT_FDCWD.
        (openat_ro): Remove.  Caller changed to use openat_permissive.
        (openat_permissive): Now a macro, if not a function.
        (openat_restore_fail, openat_save_fail): Now always functions,
        since mkdirat needs them even if __OPENAT_PREFIX is defined.

        * lib/openat-priv.h: New file, defining macros used by mkdirat.c
        and openat.c.
        * lib/mkdirat.c: Include openat-priv.h.
        Remove definitions of macros defined therein.
        * lib/openat.c: Likewise.

        * lib/openat.h (mkdirat): Declare.

        * lib/openat.c (fdopendir): Don't change errno when returning non-NULL.

        * lib/openat.h (openat_permissive): Declare.
        (openat_ro): Define.

        * lib/openat.c (EXPECTED_ERRNO): New macro.
        (openat_permissive): New function -- used in remove.c rewrite.
        (all functions): Set errno just before returning, only if there
        was an actual failure.
        Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.

        Emulate openat-family functions using Linux's procfs, if possible.
        Idea and some code based on Ulrich Drepper's glibc changes.

        * lib/openat.c: (BUILD_PROC_NAME): New macro.
        Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h".
        (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
        before falling back on save_cwd and restore_cwd.
        (fdopendir, fstatat, unlinkat): Likewise.

        * lib/openat.c (fstatat, unlinkat): Perform the syscall directly,
        skipping the save_cwd...restore_cwd overhead, if FILE is absolute.

        * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t,
        as second argument to va_arg.  Otherwise, some versions of gcc
        warn that `if this code is reached, the program will abort'.

        * lib/memxor.h, lib/memxor.c: New files.

        * lib/getaddrinfo.h: Don't protect sys/types.h with HAVE_SYS_TYPES_H,
        we assume all systems have it, suggested by Jim Meyering
        <jim@meyering.net>.  Remove HAVE_SYS_SOCKET_H test too, to see if
        any systems lack sys/socket.h; mingw32 is known to lack it, but we
        don't support it yet anyway.  Also remove HAVE_NETDB_H test, for
        same reasons.

2005-10-05  Simon Josefsson  <jas@extundo.com>

        * m4/ullong_max.m4 (gl_ULLONG_MAX): Simplify so that it merely
        defines ULONG_MAX_LT_ULLONG_MAX.  Thomas M.Ott reports that
        ULLONG_MAX doesn't work with 2.7.2.1.

2005-10-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/.cvsignore: Add fts.h, search.h, t-fpending.
        * lib/settime.c (settime): Fix { typo in previous patch.  Also, don't
        bother returning ENOSYS if settimeofday or stime fails; just let
        them return whatever errno they want to return.
        * lib/utimens.c: Include unistd.h, for dup2.
        (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
        (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.

        * lib/fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.

        `#if HAVE_CONFIG_H'.
        * lib/openat.c (fdopendir): Do not define if HAVE_FDOPENDIR.
        Remove AT_FDCWD test.
        Do not consume the fd unless successful.
        * lib/openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
        * lib/settime.c (settime): Move the HAVE_STIME block `up' into an #elif
        block, so that we don't even try to compile it if settimeofday is
        available.  This works around a compilation failure on OSF1 V5.1,
        due to stime requiring a `long int*' while tv_sec is `int'.

        and Darwin.

        * m4/getaddrinfo.m4: Use AC_GNU_SOURCE, GNU only declare getaddrinfo
        as an (POSIX) extension.  Check for sys/types.h, sys/socket.h, and
        netdb.h too, needed by getaddrinfo.h.  Check if getaddrinfo,
        freeaddrinfo and gai_strerror are declared by the POSIX headers.
        Check if struct addrinfo is declared.

2005-10-01  Simon Josefsson  <jas@extundo.com>

        * lib/getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.
        Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO.  Protect
        AI_* and EAI_* definitions.  Protect function declarations.

        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Look for getservbyname in these
        libraries [inet nsl socket xnet].  Nelson Beebe reported that with
        native cc on Solaris 7, getaddrinfo.c requires -lsocket.
        * m4/getaddrinfo.m4 (gl_GETADDRINFO): Check for gethostbyname
        in the inet and nsl libraries.  Required on Solaris 5.7.

2005-10-01  Eric Blake  <ebb9@byu.net>  (tiny change)

        * lib/getdelim.c (getdelim): Remove unused variables.

2005-09-29  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xtime.h (XTIME_PRECISION): Now of type int, not long long int,
        so that the code works even with ancient cpp.  Portability problem
        with GCC 2.7.2.1 reported by Thomas M.Ott.

2005-09-27  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (Depends-on): Add strcase.

        * modules/gethostname (Licence): Change from GPL to LGPL, since
        gethostname.c is a trivial implementation of a standard library
        function.
        * modules/poll (License): Change from GPL to LGPL, since it's
        derived from LGPL code.

2005-09-27  Jim Meyering  <jim@meyering.net>

        * lib/getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef
        HAVE_CONFIG_H.

        * lib/intprops.h (signed_type_or_expr__): Define.
        (INT_STRLEN_BOUND) [__GNUC__]: Use a slightly tighter bound
        for unsigned types.

2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/verify.h (verify_expr): Remove, replacing with:
        (verify_true): New macro that returns true instead of void.
        (verify_type__): Remove.
        (verify): Use verify_true rather than verify_type__.

2005-09-26  Bruno Haible  <bruno@clisp.org>

        * modules/mbchar (Include): Mention that HAVE_WCHAR_H && HAVE_WCTYPE_H
        is necessary.
        (lib_SOURCES): Remove mbchar.c.
        * modules/mbfile (Include): Mention that HAVE_MBRTOWC is necessary.
        (Files): Add m4/mbrtowc.m4.

        compile mbchar.c if they are not both present.

2005-09-25  Jim Meyering  <jim@meyering.net>

        * modules/inet_ntop (Depends-on): Add socklen, since inet_ntop.c
        also uses socklen_t.

2005-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (ENOSYS): Define if not already defined.
        (futimens): Support having a null PATH if the file descriptor
        is nonnegative.

        * lib/regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
        Remove.
        (__attribute): Define to empty unless GCC 3.1 or later.
        This works around a core dump on OpenBSD 3.4, which has GCC
        2.95.3, which dumps core when given __attribute__(()).  It also
        simplifies other tests, since we really don't want to bother with
        worrying about which ancient version of GCC supported what.
        Original problem reported by Yoann Vandoorselaere, with part of
        the fix suggested by Derek Price.

2005-09-24  Jim Meyering  <jim@meyering.net>

        * lib/verify.h (verify_type__): Use `unsigned int' as the bitfield type
        so we can once again use a positive bitfield width of 1 -- now we
        don't have to explain why we were using a bitfield width of 2.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): If replacing, define regcomp to rpl_regcomp,
        and similarly for the other external symbols.  Problem reported
        by James Gallager.

        * m4/fnmatch.m4 (_AC_FUNC_FNMATCH_IF): Catch Sun Studio 10u1 on Linux
        bug reported by Jim Meyering.

        * m4/utimens.m4 (gl_UTIMENS): Check for futimesat.
        * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Undo previous change;
        not needed, since socklen is a prerequisite module.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
        Problem reported by Eric Blake.
        (getaddrinfo): Initialize se so that it's not garbage.
        Redo internal storage allocation so that it doesn't make unportable
        assumptions about alignment.
        Fix a memory leak.

        * lib/utimens.c (futimens): Use futimesat if available.
        Prefer it to futimes since it doesn't have the futimes bug.

        * lib/verify.h (GL_CONCAT0, GL_CONCAT): Remove.
        (verify): Don't use the __LINE__ trick, as it doesn't work in general.
        Instead, declare a function that returns a pointer to an array,
        and use verify_type__ to declare the size of the array.
        Problem and germ of a solution reported by Bruno Haible.
        (verify_type__): Use 2, not 1, for bitfield size, to avoid
        a warning with Irix 6.5 cc.  Problem reported by Bruno Haible.

        each time through the loop.  Do not diagnose restore_cwd failure;
        that is the caller's job (and perhaps the caller does not care).

        * lib/mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
        (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
        If the file already exists but is not a directory, don't bother
        to try to make its parents.
        Close potential file descriptor leak if we can't chdir("/") (!).
        Don't always return true if chdir($PWD) fails; return true only
        if the requested action was done successfully (except for the
        chdir($PWD)).
        Don't log final directory unless we actually made it.
        Refactor to avoid duplicate code to fix up permissions.
        Don't attempt to fix up parent permissions if chdir($PWD) fails.

        * lib/strftime.c (my_strftime): Rewrite the previous change slightly,
        to make it a bit faster and (I hope) clearer.
        * lib/strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
        Fix bug in formats like %2N.

        * lib/verify.h: New file.

2005-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Check for netinet/in.h.

2005-09-22  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        * m4/lstat.m4 (gl_FUNC_LSTAT):
        Use AC_LIBSOURCES to require lstat.c and lstat.h.
        Remove obsolete comment.
        * m4/xreadlink.m4: Use AC_LIBSOURCES and AC_LIBOBJ.
        * m4/xstrtod.m4: Likewise.

        * m4/openat.m4 (gl_FUNC_OPENAT): Add openat-die.c.

2005-09-22  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        * lib/backupfile.c: Use ARGMATCH_VERIFY, just in case.

        * lib/posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
        the .tm_year member, since otherwise gcc-4.0 would now warn about
        tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.

        * lib/quotearg.c (quotearg_n_options): Change code to be suboptimal, in
        order to avoid an unsuppressible warning from gcc on 64-bit systems.

        * lib/getdate.y (get_date): Undo part of the 2005-04-04 change, so that
        the command "date -d'2005-03-27 +1 day'" succeeds once again, even
        when run in a time zone for which daylight savings time is in effect
        for the starting date.

        * lib/mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
        stop us from restricting permissions of just-created absolute-named
        directories.
        * lib/mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
        to restore initial working directory.
        * lib/mkdir-p.c (make_dir_parents): New parameter:
        different_working_dir, to tell caller if/when we change the working
        directory and are unable to return to the initial one.
        * lib/mkdir-p.h (make_dir_parents): Update prototype.
        * lib/mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
        `return false'.  This fixes a bug introduced on 2004-07-30.

        * lib/openat.c (fdopendir): Be sure to close the supplied
        file descriptor before returning.  This makes our replacement
        implementation a little closer to Solaris's, where fdopendir
        ties the file descriptor to the returned DIR* pointer.
        * lib/openat.c (unlinkat): New function.
        * lib/openat.h (unlinkat): Add prototype.
        * lib/openat-die.c (openat_save_fail): Rename from openat_save_die.
        (openat_restore_fail): Rename from openat_restore_die.
        * lib/openat.c, openat.h: Reflect s/_die/_fail/ renaming.

        Provide an alternative to exiting immediately upon save_cwd or
        restore_cwd failure.  Now, an application can arrange e.g.,
        to perform a longjump in that case.
        * lib/openat.c: Include dirname.h.
        Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
        (rpl_openat, fdopendir, fstatat): Call openat_save_die
        and openat_restore_die rather than calling error directly.
        Don't include "error.h" or "exitfail.h"; they're no longer needed.

        * lib/openat-die.c (openat_save_die, openat_restore_die): New file.
        * lib/openat.h (openat_save_die, openat_restore_die): Declare and
        define.

        * lib/strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
        size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
                            int utc, int nanoseconds);
        Background:
        date should not have to allocate a megabyte of virtual memory to
        handle a format argument like +%1048575T.  When implemented with
        strftime, it must allocate such a buffer, use strftime to fill it
        in, print it, then free it.
        With fprintftime, it simply prints everything and exits.
        With no need for memory allocation, that's one fewer way to fail.
        * lib/strftime.c (my_strftime): Parse the colons of %:::z *after* the
        optional field width, not before, so we accept %9:z, not %:9z.
        (my_strftime): Be sure to use L_('x') for literals.

        Sync from coreutils.

        * lib/getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin.
        [__linux__]: Allocate a big enough buffer for /proc/loadavg.
        [!LDAV_DONE]: Avoid unused variable warning.

2005-09-21  Bruno Haible  <bruno@clisp.org>

2005-09-20  Derek Price  <derek@ximbiot.com>

        getaddrinfo.h.

2005-09-20  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: Remove trailing slashes from the values specified for
        --source-base, --m4-base, --tests-base, --aux-dir.
        Suggested by Simon Josefsson <jas@extundo.com>.

2005-09-20  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_all_modules, func_modules_transitive_closure,
        func_modules_to_filelist, func_import, func_create_testdir): Make all
        sorting results locale-independent, so that gnulib-cache.m4 doesn't
        change when gnulib-tool is invoked in a different locale.

2005-09-19  Simon Josefsson  <jas@extundo.com>

        Renamed from their non-__ counterparts, with new macros replacing
        them if not _LIBC.  Add __THROW attribute.
        (rol): Remove.
        (struct md5_ctx): Align buffer if using GCC.
        * lib/sha1.h (struct sha1_ctx): Likewise.

        * lib/glob-libc.h: Renamed from glob_.h.  The new version is
        taken from libc's glob.h, except with '#ifdef __GLOB_GNULIB'
        protecting things that should be done only in gnulib contexts.
        * lib/glob_.h: New file, containing only the glob things needed for
        gnulib.
        (GLOB_PREFIX): Remove.  All uses changed to look for __GLOB_GNULIB.
        (__GLOB_CONCAT, __GLOB_XCONCAT, __GLOB_ID): Remove; no longer needed.
        (glob, globfree, glob_pattern_p): Now defined simply in terms of
        rpl_glob, rpl_globfree, rpl_glob_pattern_p.
        (__GLOB_GNULIB): New macro, to keep the glob.h changes clearer
        and to respect the namespace rules better.

        glibc's.

2005-09-08  Paul Eggert  <eggert@cs.ucla.edu>

2005-09-05  Paul Eggert  <eggert@cs.ucla.edu>

        Change bitset word type from unsigned int to unsigned long int,

        * lib/regcomp.c (build_equiv_class, build_charclass, build_range_exp):
        (build_collating_symbol):
        Prefer bitset to re_bitset_ptr_t in prototypes, when the actual
        argument is a bitset.  This is merely a style issue, but it makes
        it clearer that an entire array is expected.
        (re_compile_fastmap_iter, init_dfa, init_word_char, optimize_subexps):

        (bitset_set, bitset_clear, bitset_contain, bitset_empty):
        (bitset_set_all, bitset_copy):  Now inline functions, not macros.
        (bitset_empty, bitset_copy):
        Prefer sizeof (bitset) to multiplying it out ourselves.
        (bitset_not_merge): Remove; unused.
        (bitset_contain): Return bool, not unsigned int with one bit on.
        All callers changed.
        * lib/regexec.c (build_trtable): Don't assume bitset has no stricter
        alignment than re_node_set; do this by defining a new internal
        type struct dests_alloc and using it to allocate memory.

2005-09-02  Paul Eggert  <eggert@cs.ucla.edu>

        Check for arithmetic overflow when calculating sizes, to prevent

        I inserted a run-time check.

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
        old glibc regex code mishandles strings longer than 2**31 bytes.
        This patch fixes this when the regex code is used in gnulib
        (i.e., outside glibc).

        This patch should not affect the use of the regex code inside
        glibc.  No doubt this problem also needs to be handled for glibc
        as well, but the result will be an incompatible change to the
        glibc ABI, and the old ABI will have to be supported too.  That
        can be the the subject for another patch.

        * lib/regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro,
        governing whether the rest of this patch is active.  By default,
        the macro is disabled and the patch has no effect.

        New macros.

        (re_string_elem_size_at):
        Use the new types and macros to port to 64-bit hosts.

        * lib/regexec.c (check_dst_limits_calc_pos_1): Likewise;
        in one case, a <= should have been an <, and in another case the
        whole test was missing.
        * lib/regex_internal.h (BYTE_BITS): Remove.  All uses changed to
        the standard name CHAR_BIT.
        * lib/regexec.c (match_ctx_add_entry): Don't assume that ~0 == -1;
        this is not true on one's complement and signed-magnitude hosts.

        * lib/regex_internal.h (re_sub_match_top_t): Remove unused member
        next_last_offset.
        (struct re_dfa_t): Remove unused member states_alloc.
        * lib/regcomp.c (init_dfa): Don't initialize unused members.

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Require AC_SYS_LARGEFILE, Define
        _REGEX_LARGE_OFFSETS).  Test for regoff_t/off_t bug in 64-bit
        and large-file glibc and in 32-bit large-file Solaris.

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_string_reconstruct): Don't assume buffer
        lengths fit in regoff_t; this isn't true if regoff_t is the same
        width as size_t.
        * lib/regex.c (re_search_internal): 5th arg is LAST_START
        (= START + RANGE) instead of RANGE.  This avoids overflow
        problems when regoff_t is the same width as size_t.
        All callers changed.
        (re_search_2_stub): Check for overflow when adding the
        sizes of the two strings.
        (re_search_stub): Check for overflow when adding START
        to RANGE; if it occurs, substitute the extreme value.

        * lib/regex_internal.c (create_ci_newstate, create_cd_newstate):
        (register_state): Likewise.
        * lib/regexec.c (search_cur_bkref_entry, check_dst_limits):
        (check_dst_limits_calc_pos_1, check_dst_limits_calc_pos):
        (group_nodes_into_DFAstates): Likewise.

2005-08-31  Jim Meyering  <jim@meyering.net>

        the generated files.
        (func_import): Don't set cmd.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * lib/strstr.c: Include <stddef.h>, for NULL.
        * lib/strcasestr.c: Likewise.
        Reported by Yoann Vandoorselaere <yoann.v@prelude-ids.com>.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: New option --macro-prefix.
        (func_import): Use macro_prefix.
        (import): Handle option --macro-prefix.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (import): Rename most ac_* variables to cached_*.
        Also use new variables cached_lgpl, cached_libtool.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Require AC_GNU_SOURCE etc. instead of
        always instantiating them.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Read the previous cached settings
        from gnulib-cache.m4 and gnulib-comp.m4. Remove files that were
        earlier added by gnulib but are now dropped. Warn when a gnulib file
        overwrites a non-gnulib file.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Generate two files gnulib-cache.m4 and
        gnulib-comp.m4 instead of a single gnulib.m4, to make it easy for
        projects that don't keep autogenerated files in CVS. Put into
        actioncmd only the specified modules, not the transitive closure.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Fix defaulting of $libname and $libtool.
        Create directories that shall be filled.
        (import): Don't look for gl_* macros in configure.ac. Recurse across
        all directories containing a gnulib-cache.m4 files, if meaningful.

2005-08-31  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_import): Emit also a stub for gl_LIBTOOL.

2005-08-29  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool: Enclose all occurrences of $destdir in "...", so
        that it works when the directory contains spaces.

2005-08-29  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (import): Avoid unnecessary spaces in $avoidlist.

2005-08-29  Bruno Haible  <bruno@clisp.org>

        Emit more advice.

2005-08-29  Bruno Haible  <bruno@clisp.org>
        and Stepan Kasal  <kasal@ucw.cz>

        * check-module: If more parameters are given, check each of them
        separately; add more exceptions, as noted by Jim Meyering.
        (check_module): New procedure.
        (%exempt_header): Now contains all exceptions.

2005-08-29  Ben Pfaff  <blp@cs.stanford.edu>

        * modules/byteswap (Makefile.am): Fix rule to not assume GNU make.

2005-08-29  Oskar Liljeblad  <oskar@osk.mine.nu>

        * lib/iconvme.c: Split iconv_string into iconv_alloc.

2005-08-28  Bruno Haible  <bruno@clisp.org>

        AC_LIBSOURCES list and arrange to compile it via AC_LIBOBJ.
        * m4/unistd-safer.m4 (gl_UNISTD_SAFER): Likewise, add pipe-safer.c.
        Add pipe-safer.c and unistd--.h to the AC_LIBSOURCES list.

2005-08-27  Jim Meyering  <jim@meyering.net>

        * lib/fopen-safer.c: Merge minor changes from coreutils.
        * lib/dup-safer.c: Likewise.
        * lib/fd-safer.c: Likewise.

        * lib/stdlib--.h: New file.
        * lib/mkstemp-safer.c: New file.

        GNU tar needs these.
        * lib/pipe-safer.c: New file.
        * lib/creat-safer.c: New file.

2005-08-26  Simon Josefsson  <jas@extundo.com>

        * lib/getpass.c: Use _WIN32 instead of WIN32, suggested by Bruno
        Haible <bruno@clisp.org>.

2005-08-26  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.h: Remove all references to
        RE_NO_INTERNAL_PROTOTYPES; no longer neeeded now that we assume C89
        or better.
        (bitset_not, bitset_merge, bitset_not_merge):
        (bitset_mask, re_string_allocate, re_string_construct):
        (re_string_reconstruct, re_string_destruct, re_string_elem_size_at):
        (re_string_char_size_at, re_string_wchar_at, re_string_peek_byte_case):
        (re_string_fetch_byte_case, re_node_set_alloc, re_node_set_init_1):
        (re_node_set_init_2, re_node_set_init_copy, re_node_set_add_intersect):
        (re_node_set_init_union, re_node_set_merge, re_node_set_insert):
        (re_node_set_insert_last, re_node_set_compare, re_node_set_contains):

        now that the function decl has been removed.
        * lib/regex_internal.c (re_string_peek_byte_case):
        (re_string_fetch_byte_case, re_node_set_compare, re_node_set_contains):
        Likewise.

2005-08-25  Stepan Kasal  <kasal@ucw.cz>

        * m4/regex.m4: Add AC_PREREQ(2.50).
        (gl_REGEX): If --with-included-regex was given, skip the autodetection.

2005-08-25  Simon Josefsson  <jas@extundo.com>

        * m4/getpass.m4: Check for termios.h, tcgetattr, tcsetattr, and
        __fsetlocking.

2005-08-25  Simon Josefsson  <jas@extundo.com>

        * lib/getpass.c: Add WIN32 implementation.  Conditionalize use of
        termios.h, tcgetattr, tcsetattr and __fsetlocking.  Remove some
        GLIBC specific code.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        Make regex safe for g++.  This fixes one real bug (an "err"
        that should have been "*err").  g++ problem reported by
        Sam Steingold.
        * lib/regex_internal.h (re_calloc): New macro, consistent with
        re_malloc etc.  All callers of calloc changed to use re_calloc.
        * lib/regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,
        not int.  All callers changed.
        * lib/regcomp.c (re_compile_fastmap_iter): Don't use
        alloca (mb_cur_max); just use an array of size MB_LEN_MAX.
        * lib/regexec.c (push_fail_stack): Use re_realloc, not realloc.
        (find_recover_state): Change "err" to "*err"; this fixes what
        appears to be a real bug.
        (check_arrival_expand_ecl_sub): Be consistent about reg_errcode_t
        versus int.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (Depends-on): Add malloc, since the code
        assumes that !malloc(0) means failure.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regexec.c (set_regs): Don't alloca with an unbounded size.

        alloca modernization/simplification for regex.
        * lib/regex.c: Remove portability cruft for alloca.  This no longer
        needs to be at the start of the file, and can be moved into
        regex_internal.h and simplified.
        * lib/regex_internal.h: Include <alloca.h>.
        (__libc_use_alloca) [!defined _LIBC]: New macro.
        * lib/regexec.c (build_trtable): Remove "#ifdef _LIBC", since the code
        now works outside glibc.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1241, 1245.

2005-08-25  Jim Meyering  <jim@meyering.net>

        * lib/open-safer.c: Include <config.h>.
        Otherwise, we'd lose LARGEFILE support in any file using
        e.g. "fcntl--.h"

2005-08-25  Bruno Haible  <bruno@clisp.org>

        * m4/minmax.m4: Require autoconf 2.52.
        (gl_MINMAX_IN_HEADER): Add comments. Use m4_pushdef/m4_popdef instead
        of define/undefine. Use AS_TR_SH and AS_TR_CPP as more robust
        alternatives of translit over the alphabet.
        Based on a patch from Stepan Kasal <kasal@ucw.cz>.

2005-08-24  Simon Josefsson  <jas@extundo.com>

        * tests/test-getpass.c: New file.

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Use POSIX-compliant spellings when testing
        for GNU regex features.

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regcomp.c (regerror): 2nd arg is 'restrict', as per POSIX.
        * lib/regex.h (regerror): Likewise.

        * lib/regex.c: Do not include <sys/types.h>, as POSIX no longer
        requires this.  (The code never needed it.)

        * lib/regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
        All uses of recently-renamed identifiers changed to use the new,
        POSIX-compliant names.  The code will build and run just fine
        without these changes, but it's better to eat our own dog food
        and use the standard-conforming names.

        * lib/regex.h: Fix a multitude of POSIX name space violations.
        These changes have an effect only for programs that define
        _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
        do not change anything for programs compiled in the normal way.
        Also, there is no effect on the ABI.

        (_REGEX_SOURCE): New macro.
        Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
        defined and _GNU_SOURCE is not; this fixes a name space violation.

        Rename the following macros to obey POSIX requirements.
        The old names are still visible as macros if _REGEX_SOURCE is defined.
        (REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
        RE_BACKSLASH_ESCAPE_IN_LISTS.
        (REG_BK_PLUS_QM): renamed from RE_BK_PLUS_QM.
        (REG_CHAR_CLASSES): renamed from RE_CHAR_CLASSES.
        (REG_CONTEXT_INDEP_ANCHORS): renamed from RE_CONTEXT_INDEP_ANCHORS.
        (REG_CONTEXT_INDEP_OPS): renamed from RE_CONTEXT_INDEP_OPS.
        (REG_CONTEXT_INVALID_OPS): renamed from RE_CONTEXT_INVALID_OPS.
        (REG_DOT_NEWLINE): renamed from RE_DOT_NEWLINE.
        (REG_DOT_NOT_NULL): renamed from RE_DOT_NOT_NULL.
        (REG_HAT_LISTS_NOT_NEWLINE): renamed from RE_HAT_LISTS_NOT_NEWLINE.
        (REG_INTERVALS): renamed from RE_INTERVALS.
        (REG_LIMITED_OPS): renamed from RE_LIMITED_OPS.
        (REG_NEWLINE_ALT): renamed from RE_NEWLINE_ALT.
        (REG_NO_BK_BRACES): renamed from RE_NO_BK_BRACES.
        (REG_NO_BK_PARENS): renamed from RE_NO_BK_PARENS.
        (REG_NO_BK_REFS): renamed from RE_NO_BK_REFS.
        (REG_NO_BK_VBAR): renamed from RE_NO_BK_VBAR.
        (REG_NO_EMPTY_RANGES): renamed from RE_NO_EMPTY_RANGES.
        (REG_UNMATCHED_RIGHT_PAREN_ORD): renamed from
        RE_UNMATCHED_RIGHT_PAREN_ORD.
        (REG_NO_POSIX_BACKTRACKING): renamed from RE_NO_POSIX_BACKTRACKING.
        (REG_NO_GNU_OPS): renamed from RE_NO_GNU_OPS.
        (REG_DEBUG): renamed from RE_DEBUG.
        (REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
        (REG_IGNORE_CASE): renamed from RE_ICASE.  This renaming is a bit
        unusual, since we can't clash with the POSIX REG_ICASE.
        (REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
        (REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
        (REG_NO_SUB): renamed from RE_NO_SUB.
        (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.
        (REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.
        (REG_SYNTAX_GNU_AWK): renamed from RE_SYNTAX_GNU_AWK.
        (REG_SYNTAX_POSIX_AWK): renamed from RE_SYNTAX_POSIX_AWK.
        (REG_SYNTAX_GREP): renamed from RE_SYNTAX_GREP.
        (REG_SYNTAX_EGREP): renamed from RE_SYNTAX_EGREP.
        (REG_SYNTAX_POSIX_EGREP): renamed from RE_SYNTAX_POSIX_EGREP.
        (REG_SYNTAX_ED): renamed from RE_SYNTAX_ED.
        (REG_SYNTAX_SED): renamed from RE_SYNTAX_SED.
        (_REG_SYNTAX_POSIX_COMMON): renamed from _RE_SYNTAX_POSIX_COMMON.
        (REG_SYNTAX_POSIX_BASIC): renamed from RE_SYNTAX_POSIX_BASIC.
        (REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from
        RE_SYNTAX_POSIX_MINIMAL_BASIC.
        (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
        (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
        RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
        (REG_DUP_MAX): renamed from RE_DUP_MAX.  No need to undef it.
        (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
        (REG_REALLOCATE): Renamed from REGS_REALLOCATE.
        (REG_FIXED): Renamed from REGS_FIXED.
        (REG_NREGS): Renamed from RE_NREGS.

        (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
        of other REG_* macros, since POSIX says the user is allowed to
        #undef these macros selectively.

        (reg_errcode_t): Update comment stating what other tables need
        to be consistent.

        Rename the following enum values to obey POSIX requirements.
        The old names are still visible as macros.
        (_REG_ENOSYS): Renamed from REG_ENOSYS.  Define even if _XOPEN_SOURCE
        is not defined, since GNU is supposed to be a superset of POSIX as
        much as possible, and since we want reg_errcode_t to be a signed
        type for implementation consistency.
        (_REG_NOERROR): Renamed from REG_NOERROR.
        (_REG_NOMATCH): Renamed from REG_NOMATCH.
        (_REG_BADPAT): Renamed from REG_BADPAT.
        (_REG_ECOLLATE): Renamed from REG_ECOLLATE.
        (_REG_ECTYPE): Renamed from REG_ECTYPE.
        (_REG_EESCAPE): Renamed from REG_EESCAPE.
        (_REG_ESUBREG): Renamed from REG_ESUBREG.
        (_REG_EBRACK): Renamed from REG_EBRACK.
        (_REG_EPAREN): Renamed from REG_EPAREN.
        (_REG_EBRACE): Renamed from REG_EBRACE.
        (_REG_BADBR): Renamed from REG_BADBR.
        (_REG_ERANGE): Renamed from REG_ERANGE.
        (_REG_ESPACE): Renamed from REG_ESPACE.
        (_REG_BADRPT): Renamed from REG_BADRPT.
        (_REG_EEND): Renamed from REG_EEND.
        (_REG_ESIZE): Renamed from REG_ESIZE.
        (_REG_ERPAREN): Renamed from REG_ERPAREN.
        (REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE):
        (REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
        (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
        (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.

        (_REG_RE_NAME, _REG_RM_NAME): New macros.
        (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE.  All uses
        changed.  But support the old name if the new one is not defined
        and if _REGEX_SOURCE.

        Change the following member names in struct re_pattern_buffer.

        * gnulib-tool (func_create_megatestdir): Call autoreconf without the
        option --force, because --force causes the aclocal.m4 of each
        subdirectory to be newer than the corresponding config.h.in.

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_INCLUDED_REGEX): Remove; no longer used.
        All contents moved to gl_REGEX.
        (gl_REGEX): Don't bother checking whether lib/regex.c exists;
        assume that it does.

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h (REG_NOSYS)
        [!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]:
        Define, since POSIX requires it as of 2001.
        (_REG_ENOSYS)
        [! (defined _XOPEN_SOURCE || 200112L <= _POSIX_C_SOURCE)]:
        New private symbol, used to keep the enum signed in all cases.

        Youngman in
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-07/msg00132.html>.

2005-08-23  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1231-1233.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems reported by Sam Steingold in
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00007.html>.
        * lib/regexec.c (sift_states_bkref): Fix portability bug: the code
        assumed that reg_errcode_t is a signed type, which is not
        necessarily true if _XOPEN_SOURCE is not defined.
        * lib/regex_internal.c (calc_state_hash): Put 'inline' before type,
        since some compilers warn about it otherwise.

        * lib/regex.h (_RE_ARGS): Remove.  No longer needed, since we assume
        C89 or better.  All uses removed.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add glibc bugs 1220-1227.

2005-08-20  Jim Meyering  <jim@meyering.net>

        * lib/regexec.c (regexec, re_search_stub) [!_LIBC]: Omit declaration
        of unused local, dfa.

2005-08-20  Bruno Haible  <bruno@clisp.org>

        * m4/regex.m4 (gl_PREREQ_REGEX): Require AC_GNU_SOURCE.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_string_realloc_buffers, re_node_set_insert):
        (re_node_set_insert_last, re_dfa_add_node):
        Rename local variables to avoid GCC shadowing warnings.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex_internal.c (re_acquire_state, re_acquire_state_context)
        [defined lint]: Suppress bogus uninitialized-variable warnings.

        * lib/regcomp.c (duplicate_node): Return new index, not an error code,
        and let the caller return REG_ESPACE if out of space.  This
        removes an uninitialied-variable warning with GCC 4.0.1, and also
        avoids taking the address of a local variable.  All callers
        changed.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Comment out $LIBCSRC/posix/regex_internal.c,
        $LIBCSRC/posix/regexec.c.

2005-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/regex.h: Remove useless space-before-tab.  From coreutils.

2005-08-17  Jim Meyering  <jim@meyering.net>

        Make the %s format (seconds since the epoch) work for a negative
        number and when used with a zero-padded field width, e.g. %015s.

        * lib/strftime.c (my_strftime): Move the `do_number_sign_and_padding'
        label so that it precedes the code to set `digits'.  Otherwise,
        %0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
        print `00-22'.  Now, it prints `-0022', as it should.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * modules/strstr (Files): Add m4/mbrtowc.m4.
        (Depends-on): Add mbuiter.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * modules/strcasestr: New file.

        Add mbuiter.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * m4/strstr.m4 (gl_FUNC_STRSTR): Use the replacement function always.
        (gl_PREREQ_STRSTR): Use gl_FUNC_MBRTOWC.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * m4/strcasestr.m4: New file.

2005-08-17  Bruno Haible  <bruno@clisp.org>

        * lib/strstr.h: Ignore HAVE_STRSTR, always declare the gnulib function.

2005-08-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Do not override the results
        of gl_GETOPT_SUBSTITUTE.  That way, if both gl_GETOPT_SUBSTITUTE
        and gl_GETOPT are both invoked via different paths (as happens
        with GNU tar CVS because it uses both argp and getopt), the former
        wins.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * modules/tls: New file.
        * MODULES.html.sh (Multithreading): Add tls.

        * modules/strnlen1: New file.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * m4/strcase.m4 (gl_FUNC_STRCASECMP): Use the replacement function
        always.

        * lib/strcase.h (strcasecmp): Add note in comments.
        * lib/strncasecmp.c: Use code from strcasecmp.c.

        Solaris releases, you should also use the tzset module, but we won't
        require it as a dependency any more since we don't want LGPLed code
        to depend on GPLed code.

2005-06-28  Jim Meyering  <jim@meyering.net>

        * check-module (find_included_lib_files): Hard-code another
        pair of exceptions: fts.c includes fts-cycle.c and unistd-safer.h
        but modules/fts-lgpl (correctly) does not list those files.

        * lib/mktime.c: Include <string.h> even if !DEBUG.  (From glibc.)
        (ranged_convert): Don't save conversion in a temporary struct.
        This causes a warning with GCC 4.0.0, and anyway in the typical
        case it's not worth the extra 100 bytes or so of code.
        (ranged_convert, __mktime_internal): When calling a function via a
        pointer P, use P () rather than (*P) (), as we now assume C89 or

        (LEAVE_DIR): Fix typo: pass Fts and Ent to leave_dir.
        (struct Active_dir, AD_compare, AD_hash, enter_dir, leave_dir):
        Move to fts-cycle.c.
        (fts_open): Use setup_dir.
        (fts_close): Use free_dir.
        (fts_read): Have just one copy of the ENTER_DIR code rather than three.
        This adds a label and some gotos, but the alternatives were messier.
        Check for memory allocation failure when entering a dir.
        (fts_stat) [_LGPL_PACKAGE]: Bring back glibc cycle detection code.
        * lib/fts_.h (_LGPL_PACKAGE) [defined _LIBC]: New macro.
        (FTS): New member fts_cycle, that is a union that contains the

        if memory exhausted.  All callers changed.
        Do not bother partly cleaning up on
        memory allocation failure; that is free_dir's job.
        However, free ad if hash_insert fails, to avoid memory leak.
        (enter_dir, leave_dir): Accommodate change to FTS by inspecting
        fts->fts_options to see which union member to use.

        don't use its results.
        Don't check for fcntl.h, stddef.h, stdlib.h, string.h, unistd.h,
        since we include them unconditionally.  Don't require
        AM_STDBOOL_H, since stdbool is a prerequisite.
        Don't require AC_C_CONST, AC_TYPE_SIZE_T or check for ptrdiff_t
        since we assume C89 or better.
        Don't require AC_FUNC_CLOSEDIR_VOID, AC_FUNC_LSTAT, or AC_FUNC_STAT,
        as we don't use their results.
        Don't check for fchdir, memmove, memset, strrchr, as we use
        them unconditionally.
        * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Don't define
        GETTIMEOFDAY_CLOBBERS_LOCALTIME_BUFFER, since nobody uses it.

        Do not include intprops.h; no longer needed.

        (fts_build): Use a simpler method (not involving TYPE_SIGNED) to
        decide whether to decrement nlinks.
        * lib/fts_.h: Do not include hash.h or cycle-check.h; no longer needed.
        (FTS): Use struct hash_table * instead of Hash_table, so that
        we no longer need to include hash.h here.

2005-05-18  Jim Meyering  <jim@meyering.net>

2005-05-17  Jim Meyering  <jim@meyering.net>

        * lib/fts.c, lib/fts_.h: New files, from coreutils.

2005-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * m4/unlinkdir.m4: New file.

2005-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * lib/unlinkdir.c, lib/unlinkdir.h: New files.
        * lib/gethrxtime.c, lib/gethrxtime.h, lib/getpass.h, lib/mountlist.h,
        lib/path-concat.c, lib/regex.h, lib/unlocked-io.h, lib/xtime.h:
        White space changes only.
        * lib/makepath.c (make_path): Port to hosts where leading "//" is
        special.
        * lib/yesno.c: Include getline.h, not ctype.h.
        (yesno): Don't remove leading white space; POSIX doesn't allow it.
        Use getline to remove arbitrary restriction on response length.

2005-05-14  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist-update: Spell out "Street" in FSF postal
        mail address; this is the style the FSF seems to prefer.

        * build-aux/depcomp, build-aux/install-sh, build-aux/mdate-sh,
        build-aux/missing, build-aux/mkinstalldirs: Sync from Automake;
        this updates FSF postal mail address.

        Sync from coreutils.
        * modules/unlinkdir: New file.
        * modules/yesno (Depends-on): Add getline.
        * MODULES.html.sh (File system functions): Add unlinkdir.

        * lib/byteswap_.h, lib/getsubopt.h, lib/iconvme.h, lib/strsep.c,
        lib/strsep.h:
        Change the initial comment to refer to GPL, not LGPL.
        gnulib-tool will change it to LGPL as needed.

2005-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh, README, gnulib-tool, tests/test-base64.c,
        tests/test-memmem.c, tests/test-stpncpy.c:
        Update FSF postal mail address.

2005-05-13  Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h (int64_t, uint64_t, int_least64_t, uint_least64_t,
        int_fast64_t, uint_fast64_t, intmax_t, uintmax_t, INT64_MIN, INT64_MAX,

        INTMAX_MAX, UINTMAX_MAX, INT64_C, UINT64_C, INTMAX_C, UINTMAX_C):
        Add support for 64-bit integers in the MSVC compiler.

2005-05-12  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * modules/getdate (Makefile.am): Add getdate.c to EXTRA_DIST

2005-05-12  Eric Blake  <ebb9@byu.net>  (tiny change)

        * gnulib-tool (func_import): Sort and uniquify recommended includes.

2005-05-11  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (General date syntax): Don't say that date
        date --iso-8601=ns generates acceptable dates; it doesn't yet.
        Problem reported by Nic Ferrier.

2005-05-10  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>

        * lib/getaddrinfo.c: Don't fail when SOCK_STREAM or SOCK_DGRAM are
        specified in ai_socktype. Fix invalid ai_protocol
        check. ai_protocol is usually set to 0 or depending on
        ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP.  Checking for
        SOCK_STREAM / SOCK_DGRAM in ai_protocol was invalid.  Set
        ai_socktype / ai_protocol in the returned addrinfo structure.

2005-05-10  Simon Josefsson  <jas@extundo.com>

        * m4/getaddrinfo.m4: Look in libnsl/libsocket for getaddrinfo, from
        Yoann Vandoorselaere <yoann.v@prelude-ids.com>.

2005-05-10  Karl Berry  <karl@gnu.org>

        * doc/fdl.texi, gpl.texi, lgpl.texi, COPYING: update FSF address
        (from http://www.gnu.org/licenses).
        * doc/COPYING.LIB: also rename to COPYING.LESSER.
        * doc/COPYING.DOC: remove; per rms, only needed in doc files, so
        fdl.texi suffices.

2005-05-10  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (COPYING.LESSER): rename from COPYING.LIB.
        (COPYING.DOC): remove.

        * config/srclist-update: new FSF address.

2005-05-10  Derek Price  <derek@ximbiot.com>

        * m4/getopt.m4 (gl_GETOPT): Check for Solaris 10 bug, not decl, when
        possible.

2005-05-09  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>
            Bruno Haible  <bruno@clisp.org>

        * modules/inet_ntop: New file.
        * MODULES.html.sh (Support for systems lacking POSIX:2001): Add
        inet_ntop.

2005-05-09  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>
            Bruno Haible  <bruno@clisp.org>

2005-05-09  Yoann Vandoorselaere  <yoann.v@prelude-ids.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/inet_ntop.h: New file.
        * lib/inet_ntop.c: New file, from glibc with modifications.

2005-05-09  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/time_r (License): Change to LGPL.
        * modules/extensions (License): Change to LGPL.  Actually,
        the license is more permissive than that, but currently gnulib-tool
        doesn't know how to handle more-permissive licenses.

        * modules/stat-macros (Depends-on): Don't depend on stat-macros (!).
        Problem reported by Dave Love.

2005-05-08  Jim Meyering  <jim@meyering.net>

        * lib/classpath.c (PATH_SEPARATOR): Remove insignificant trailing
        blank.

2005-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/argmatch (Depends-on): Add stdbool.

2005-05-05  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getopt.m4 (gl_GETOPT): Check for Solaris 10 getopt, and avoid
        needless checks.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.  Among other things,
        add bulletproofing for cases where stdin, stdout, or stderr are closed.
        * lib/fd-safer.c: New file.
        * lib/fcntl-safer.h, open-safer.c: Remove.
        * lib/chdir-long.c: Fix comment "fetish" -> "coreutils".
        * lib/dup-safer.c: Include unistd-safer.h first.
        Don't include errno.h.
        (dup_safer) [!defined F_DUPFD]: Let fd_safer do the real work.
        * lib/file-type.h: Don't assume invoker included sys/stat.h first.
        * lib/file-type.c: Rely on file-type.h change.
        * lib/getloadavg.c: Include unistd-safer.h.
        (getloadavg): Use safer open.
        * lib/getusershell.c: Include "stdio-safer.h".
        (getusershell): Use safer fopen.
        * lib/long-options.c (long_options): Use NULL rather than 0.
        * lib/modechange.h (mode_free): Remove; all callers changed to invoke
        'free'.
        * lib/modechange.c: Likewise.
        xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed.
        (MODE_DONE): New constant.
        (struct mode_change): Remove 'next' member.
        (make_node_op_equals): New function; like the old one of the
        same name, except it allocates an array.
        (mode_compile, mode_create_from_ref): Use it.
        (mode_compile): Allocate result as an array, not a linked list.
        Parse octal string ourself, so that we catch mistakes like "+0".
        (mode_adjust): Arg is an array, not a linked list.
        * lib/modechange.c: Include stat-macros.h, xalloc.h.
        (S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR):
        (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU):
        (S_IRWXG, S_IRWXO, CHMOD_MODE_BITS):
        Remove.  This is now stat-macros.h's job.
        (talloc): Remove.  All callers replaced by xalloc, so that
        our invokers don't have to worry about reporting memory failures.
        (make_node_op_equals): Remove.
        (MODE_ORDINARY_CHAGE, MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        New constants.
        (struct mode_change): Moved here from modechange.h.
        (mode_append_entry): Remove.
        (mode_compile): Remove MASKED_OPS arg, since it encouraged
        apps to have incorrect behavior.  Use simpler algorithm for head
        and tail.  Don't futz with umask; that's now the job of mode_adjust.
        Detect more invalid usages rather than having somewhat-random behavior.
        Don't insert an "a=" action, as that leads to incorrect behavior.
        (mode_compile, mode_create_from_ref): Return NULL on error instead
        of an enum, since now there's only one way to have an error.  All
        callers changed.
        (mode_adjust): Accept new arg UMASK_VALUE, and interpret it

        * m4/stat-macros.m4 (gl_STAT_MACROS): New file/macro.

2005-03-22  Bruno Haible  <bruno@clisp.org>

        * config/srclist.txt: Replace target directory 'config' with

        for these modules.

2005-03-18  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (my_strftime): If the underlying strftime returns 0
        (which shouldn't happen), generate nothing instead of returning 0
        immediately, so that nstrftime (NULL, ...) doesn't return 0.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * modules/stdint (Makefile.am): Use HAVE_LONG_LONG_64BIT instead of
        HAVE_LONGLONG_64BIT.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * m4/stdint.m4 (gl_STDINT_H): Define HAVE_LONG_LONG_64BIT instead of
        HAVE_LONGLONG_64BIT.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h: Use HAVE_LONG_LONG_64BIT instead of

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (my_strftime): Prepend space to format so that we can
        reliably distinguish strftime failure from empty output on POSIX
        hosts.

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/iconvme.c (SIZE_MAX): New macro, if not already defined.
        (iconv_string): Don't guess a size-zero buffer, as that might cause
        buffer overrun.  Instead, avoid multiplying by MB_LEN_MAX if the
        result would be 'too large', where 'too large' is (heuristically)
        the square root of SIZE_MAX, divided by MB_LEN_MAX to allay
        overflow concerns.  This will prevent some unwanted malloc failures
        when the inputs are very large.

2005-03-15  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (config.rpath): from gettext.

        results.

2005-03-14  Simon Josefsson  <jas@extundo.com>

        * lib/timegm.h: Use proper prototype CPP guards, reported by Dave Love
        <fx@gnu.org>.

        * lib/mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,
        TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from
        intprops.h.
        * lib/strtol.c: Likewise.

        to be nonzero so that we (and caller) can detect the difference
        between a valid zero-length expansion and an error return, even
        when the underlying strftime fails before writing anything into
        that location.

2005-03-14  Bruno Haible  <bruno@clisp.org>

        * m4/lib-link.m4, gettext.m4, nls.m4, po.m4:

2005-03-09  Paul Eggert  <eggert@cs.ucla.edu>

        Factor int-properties macros into a single file, except for
        glibc-related files.
        * lib/intprops.h: New file.
        * lib/getloadavg.c: Include it instead of limits.h.
        (INT_STRLEN_BOUND): Remove.
        * lib/human.c: Include intprops.h.
        (group_number): Use INT_STRLEN_BOUND instead of rolling it ourself.
        * lib/human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than
        302/1000.
        * lib/inttostr.h: Include intprops.h instead of limits.h.
        (INT_STRLEN_BOUND, INT_BUFSIZE_BOUND): Remove.
        * lib/mktime.c (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT): New macros,
        for consistency with intprops.h.
        (time_t_is_integer, twos_complement_arithmetic): Use them.

        (INT_STRLEN_BOUND): Remove.
        * lib/strftime.c (TYPE_SIGNED): Remove.

        * lib/userspec.c: Include intprops.h.
        (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
        * lib/utimecmp.c, xnanosleep.c, xstrtol.c: Likewise.
        * lib/utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
        instead of rolling our own expressions.
        * lib/xstrtol.c: Include xstrtol.h first, to test interface.

        * lib/strftime.c: Include <stdbool.h>.  Use bool where appropriate,
        instead of int.
        (my_strftime): Do not mishandle years close to INT_MAX, by doing
        the right thing even if adding 1900 would overflow.  Similarly
        for tm_mon + 1 and tm_yday + 1.
        Make %Y always equivalent to %C%y, and similarly for %G and %g.
        (DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
        (DO_SIGNED_NUMBER): New macro.
        (my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1.

2005-03-07  Bruno Haible  <bruno@clisp.org>

        (func_import): Only replace files via --import when they have actually
        changed.

2005-03-03  Derek R. Price  <derek@ximbiot.com>

        * m4/mmap-anon.m4: New file.
        * m4/pagealign_alloc.m4: New file.

2005-03-03  Bruno Haible  <bruno@clisp.org>

        * m4/inttypes.m4, isc-posix.m4, once-only.m4:
        Use an all-permissive copyright notice, recommended by RMS.

2005-03-02  Bruno Haible  <bruno@clisp.org>

        * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Undo the replacement here. Because
        of AIX, the replacement has to be done only after <string.h> is
        included, therefore not in config.h. stpncpy.h does the replacement,
        and stpncpy.c uses it.

2005-03-02  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.h (stpncpy): Define as a macro without arguments, so that
        stpncpy.c uses it.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
        The workaround isn't strictly needed for POSIX conformance, and
        it's too much of a pain to configure and maintain.  We'll ask
        people to fix their kernels instead.
        * lib/xnanosleep.c: Don't include gethrxtime.h or xtime.h.
        (NANOSLEEP_BUG_WORKAROUND): Remove.
        (xnanosleep): Remove the workaround.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/gettime (Makefile.am): Remove lib_SOURCES line.
        Reported by Derek Price.
        (Include): Add "timespec.h".

        * modules/xnanosleep (Depends-on): Remove gethrxtime.

        (configure.ac): Add gl_XNANOSLEEP.
        (Makefile.am): Remove lib_SOURCES line.

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/gethrxtime.h, lib/gethrxtime.c, lib/xtime.h: New files.
        * lib/timespec.h (gettime): Return void, since it always
        succeeds now.  All uses changed.
        * lib/gettime.c (gettime): Likewise.
        [HAVE_NANOTIME]: Prefer nanotime.
        Assume gettimeofday succeeds, as POSIX requires.
        Assime time () succeeds, since other code already does.
        * lib/xnanosleep.c: Include xtime.h and gethrxtime.h, not xalloc.h.
        (timespec_subtract): Remove.
        (NANOSLEEP_BUG_WORKAROUND): New constant.
        (xnanosleep): Use gethrxtime rather than gettime; this simplifies
        things considerably.  Use it only on GNU/Linux hosts, since the
        workaround shouldn't be needed elsewhere.

2005-02-24  Bruno Haible  <bruno@clisp.org>

        * modules/gettext (Files): Add m4/glibc2.m4.

2005-02-24  Bruno Haible  <bruno@clisp.org>

2005-02-20  Neil Conway  <neilc@samurai.com>

        * lib/xgethostname.c (xgethostname): Check for ENOMEM, which is
        returned by OSX/Darwin if the specified buffer is not large
        enough for the hostname.

2005-02-03  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/argp-help.c (__argp_help): Create a fake struct argp_state and
        pass it to _help, otherwise the latter coredumps trying to

        same value as for Solaris 9.

        * lib/chdir-long.c (chdir_long): Rewrite to remove limitation on
        component length.  This included changing the parameter to be
        of type `char *' rather than `char const *'.

        * lib/openat.c (fdopendir, fstatat): New functions.

        * MODULES.html.sh (Sizes of integer types <limits.h>): New element,
        with new ullong_max module.

2005-01-19  Bruno Haible  <bruno@clisp.org>

        * modules/sh-quote: New file.
        * MODULES.html.sh (Executing programs): Add sh-quote.

2005-01-19  Bruno Haible  <bruno@clisp.org>

        * lib/sh-quote.h: New file, from GNU gettext.
        * lib/sh-quote.c: New file, from GNU gettext.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.
        * m4/ullong_max.m4: New file.
        * m4/jm-macros.m4 (gl_MACROS): Require gl_ULLONG_MAX.
        (gl_MACROS): Assume localeconv exists.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        Merge changes from coreutils, as described below in several
        changelogs dated today.

        * lib/save-cwd.c: Include "save-cwd.h" before other include files.
        (O_DIRECTORY): Remove; not needed here, since "." must be
        a directory.  All uses removed.
        (save_cwd): Use __sgi || __sun, not sun || __sun.  __sun is
        universal on Suns, and we also need to test for IRIX.
        Revamp code to use 'if' rather than '#if'.
        Avoid unnecessary comparison of cwd->desc to 0.

        * lib/utimens.c (futimens): Robustify the previous patch, by checking
        for known valid error numbers rather than observed invalid ones.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/ullong_max: New file.

        * modules/chdir-long, modules/openat: New files.

        * m4/chdir-long.m4, m4/openat.m4: New files.
        * m4/save-cwd.m4 (gl_SAVE_CWD): Add AC_LIBSOURCES for save-cwd.c,
        save-cwd.h.  Add AC_LIBOBJ for save-cwd.
        * m4/chown.m4 (gl_FUNC_CHOWN): When cross-compiling, assume that chown
        is sane and DOES follow symlinks.  Besides, testing 20 different
        systems found no broken chown implementations.
        Prompted by a change in rsync's copy of this macro.
        * m4/jm-macros.m4 (gl_MACROS): Require gl_FUNC_CHDIR_LONG.

        * m4/lchown.m4 (gl_FUNC_LCHOWN): Use AC_LIBSOURCES.

        * m4/utimes.m4: Work around tests/touch/empty-file failure on a system
        (sparc64, Linux-2.4.28, glibc-2.3.3) that didn't honor utimes'
        NULL-means-set-to-current-time semantics.
        Remove temporary file immediately, rather than waiting
        for configure's at-exit trap code to do it.

2005-01-18  Jim Meyering  <jim@meyering.net>

        * lib/version-etc.c (version_etc_copyright): Update copyright date.

        * lib/utimens.c (futimens): Account for the fact that futimes
        can also fail with errno == ENOSYS or errno == ENOENT.
        Patch from Dmitry V. Levin.

        Change the name of the robust chdir function from chdir to chdir_long.
        * lib/save-cwd.c: Include chdir-long.h rather than chdir.h.
        (restore_cwd): Use chdir_long, not chdir.
        * lib/chdir-long.c: Renamed from chdir.c.
        * lib/chdir-long.h: Renamed from chdir.h.
        [!defined PATH_MAX]: Define chdir_long to chdir on systems like the
        Hurd.

        native HP-UX 11.0 ANSI C compiler.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.c: Remove HAVE_STPNCPY and gnu_stpncpy renaming,
        redundant because stpncpy.m4 takes care of it.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/progreloc.c: Include xalloc.h instead of xmalloc.h.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/progreloc.c (xstrdup): Define as strdup if no xmalloc should be
        used.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/fwriteerror.h (fwriteerror): Change specification to include
        fclose.
        * lib/fwriteerror.c: Include <stdbool.h>.

        * lib/execute.c (environ): Declare if needed.
        * lib/pipe.c (environ): Likewise.

        * lib/human.c (SIZE_MAX, UINTMAX_MAX): Move these conditional
        definitions to be after all include files, to avoid collisions.
        Problem reported by Bob Proulx.

2005-01-04  Jim Meyering  <jim@meyering.net>

        Changes imported from coreutils.
        * m4/mkstemp.m4 (gl_FUNC_MKSTEMP): Rather than using "conftestXXXXXX"
        as the mkstemp template, use a temporary directory and an
        8.3-friendly template to avoid trouble on systems like DJGPP.
        Reported by Juan M. Guerrero via Stepan Kasal.
        * m4/(gl_FUNC_MKSTEMP): Include <unistd.h> for the declaration of
        close. Remove the temporary directory right away, rather than waiting
        for configure's at-exit trap code to do it.
        Suggestion from Stepan Kasal.

2005-01-01  Simon Josefsson  <jas@extundo.com>

        * gnulib-tool: Print #include directives when --import'ing.

2004-12-28  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/error.c [!_LIBC && !ENABLE_NLS]: Do not include "gettext.h";
        not needed.  This removes a dependency on the gettext module.
        [defined _LIBC]: Do not include <libintl.h>; not needed.

2004-12-24  Paul Eggert  <eggert@cs.ucla.edu>

        (parser_init): Don't assume that void * is aligned sufficiently
        for struct option.

        * lib/getdate.y (YYSTACK_USE_ALLOCA): Define to 0, since there's no
        need to extend the stack.
        (YYINITDEPTH): New macro, so that the initial stack isn't overly
        large.

2004-12-22  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/argp-parse.c (parser_init): Avoid arithmetics on void pointers.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/regex (lib_SOURCES): Remove regex.c, undoing previous
        (2004-10-24) change.  Apparently this was a false alarm.

        * modules/getdate: Depend on alloca-opt, not alloca.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/alloca_.h: Conditionalize on _GNULIB_ALLOCA_H, not _ALLOCA_H.

2004-12-18  Simon Josefsson  <jas@extundo.com>

        * modules/alloca: Depend on alloca-opt, instead of duplicating it.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Also test for sigaction.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * lib/fatal-signal.c (fatal_signals): Make non-const.
        (init_fatal_signals): New function.
        (uninstall_handlers, install_handlers): Ignore signals that were set to
        SIG_IGN.
        (at_fatal_signal): Call init_fatal_signals.
        (init_fatal_signal_set): Likewise. Ignore signals that were set to
        SIG_IGN.
        Reported by Paul Eggert.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * doc/alloca.texi: New file.
        * doc/alloca-opt.texi: New file.

2004-12-17  Jim Meyering  <jim@meyering.net>

        * config/install-sh: Use `(exit N); exit N', not `(exit N); exit'.
        Otherwise, install-sh could exit with improper exit status when
        exiting via a trapped interrupt.  Thanks to a report from Bob Proulx.

2004-12-16  Simon Josefsson  <jas@extundo.com>

        * tests/test-base64.c: Add license.

2004-12-15  Stepan Kasal  <address@hidden>

        Suggested by Mark D. Baushke.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getdate.y (textint): New member "negative".
        (time_zone_hhmm): New function.
        Expect 14 shift-reduce conflicts, not 13.
        (o_colon_minutes): New rule.
        (time, zone): Use it to add support for +HH:MM, UTC+HH:MM.
        (yylex): Set the "negative" member of signed numbers.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (Time of day items, Time zone items):
        Describe new formats +00:00, UTC+00:00.

2004-12-07  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Fix typo in previous change:
        spurious "-l"s.  Problem reported by Stepan Kasal.

2004-12-06  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): New macro, to work around bug
        in Autoconf 2.59.  Problem reported by Mark D. Baushke.

2004-12-04  Simon Josefsson  <jas@extundo.com>

        * modules/getaddrinfo (License): Add LGPL, reported by Yoann
        Vandoorselaere <yoann@prelude-ids.org>.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        Changes imported from coreutils.
        * m4/hard-locale.m4 (gl_HARD_LOCALE): Assume locale.h and setlocale
        exist.
        * m4/human.m4 (gl_HUMAN): Assume locale.h and localeconv exist.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        Changes imported from coreutils.
        * lib/hard-locale.c: Assume <locale.h> exists.
        Include "strdup.h".
        (GLIBC_VERSION): New macro.

2004-12-01  Jakub Jelinek  <jakub@redhat.com>

        * lib/mktime.c (__mktime_internal): If SEC_REQUESTED != SEC,
        convert T2, not T.  (Imported from libc.)

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * modules/restrict (License): Change to LGPL.

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * m4/restrict.m4: Add copyright and copying conditions.

2004-11-30  Simon Josefsson  <jas@extundo.com>

        * tests/test-base64.c: New file.

        * modules/base64: New file.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX):
        Define HAVE_PARTLY_WORKING_GETCWD if getcwd is partly working.

        * m4/readutmp.m4 (gl_READUTMP): Don't check for sys/param.h.

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getcwd.c (is_ENAMETOOLONG): New macro.
        (__getcwd.c): Don't restore errno; glibc doesn't.
        [HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd
        first, falling back to our code only if its results look suspicious.
        Ensure that the resulting buffer is only as large as necessary.

        * lib/readutmp.c: Include readutmp.h first.
        Include <errno.h>, since readutmp.h no longer does that.
        * lib/readutmp.h: Don't include <errno.h>,
        <sys/param.h>, <time.h>; not needed to establish interface.
        (errno): Remove decl.
        (HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed.
        (UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME,
        UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros.

2004-11-28  Simon Josefsson  <jas@extundo.com>

        * lib/base64.h, base64.c: New file.

2004-11-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getcwd.h: New file, which I forgot to check in on 2004-11-25.

2004-11-26  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/getcwd (Files): Add lib/getcwd.h, m4/getcwd.m4.
        (Depends-on): Remove pathmax, same.  Add mempcpy.
        (configure.ac): GL_FUNC_GETCWD_PATH_MAX -> gl_FUNC_GETCWD.
        (Makefile.am): Append getcwd.h to lib_SOURCES.
        (Include): Add getcwd.h.
        (Maintainer): Change from Jim Meyering to "all, glibc",
        since getdate now uses intended-for-glibc code.
        * modules/xgetcwd (Files): Remove m4/getcwd.m4.
        (Depends-on): Depend on getcwd.  Do not depend on pathmax.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems reported by Scott S. Tinsley for HP-UX 11.11 using
        HP's ANSI C compiler.
        * lib/fsusage.c (statvfs) [HAVE_SYS_STATVFS_H]: Remove decl.
        Declaring int functions causes warnings on some modern systems and
        shouldn't be needed to compile on ancient ones.
        * lib/same.c (MIN) [defined MIN]: Don't define, since it's already
        defined.

        * lib/getcwd.c: Replace by a copy of glibc/sysdeps/posix/getcwd.c, but
        with the following changes.
        (__set_errno): Parenthesize properly.
        Include <stdbool.h>.
        (MIN, MAX, MATCHING_INO): New macros.
        (__getcwd): Define with prototype, not K&R form.
        Use heuristics to allocate default buffer on stack if possible.
        If AT_FDCWD is defined, use openat and fstatat to avoid O(N**2)
        behavior, and to avoid the PATH_MAX limit when computing
        ../../../../...
        Use MATCHING_INO to compare inode number to file.
        Check for arithmetic overflow in size calculations.
        Fix bug in reallocation of dot array that caused getcwd to fail
        on directories nested deeper than 75.
        Be more careful about saving errno on error.
        Do not use realloc; use only free+malloc, as this is a bit
        more flexible and avoids a needless copy operation.
        Do not inspect st_dev and st_ino for symbolic links; POSIX
        doesn't specify the latter.
        Check for closedir errors.
        Avoid needless casts.
        Use "#ifdef weak_alias" around weak_alias, to be like other
        glibc code.
        The following changes to getcwd.c have effect only when used in
        gnulib; they have no effect inside glibc proper.
        (#pragma alloca) [defined _AIX && !defined __GNUC__]: Remove,
        as alloca isn't used.
        (alloca, __alloca): Likewise.
        [!_LIBC]: Include "getcwd.h", "mempcpy.h".
        Include <stddef.h>, <stdlib.h>, <string.h>, <limits.h>
        unconditionally, as gnulib assumes C89 or better.
        Do not include <sys/param.h>.
        (errno) [!defined __GNU_LIBRARY__ && !defined STDC_HEADERS]: Remove
        no-longer-necessary 'extern int errno' decl; gnulib assumes C89 or
        better.
        (NULL) [!defined NULL]: Remove; we assume C89 or better.
        Include <dirent.h> in a way that is compatible with modern Autoconf.
        (_D_ALLOC_NAMELEN, _D_EXACT_NAMLEN):
        New macros, if not already defined.
        Include <unistd.h> if _LIBC, not if __GNU_LIBRARY__.
        Use "_LIBC", not "defined _LIBC", for consistency.
        (HAVE_MEMPCPY): Remove; no longer needed now that gnulib has
        a mempcpy module.
        (__lstat, __closedir, __opendir, __readdir) [!_LIBC]: New macros.
        (GETCWD_RETURN_TYPE): Remove.  All uses replaced by char *.
        * lib/xgetcwd.c: David MacKenzie's old code was removed, so give
        credit only to Jim Meyering and adjust the copyright dates.
        Do not include <limits.h>, <stdio.h>, <sys/types.h>,
        <stdlib.h>, <unistd.h>, "pathmax.h".
        Instead, include "xgetcwd.h" (first) and "getcwd.h".
        (INITIAL_BUFFER_SIZE): Remove.
        (xgetcwd): Rely on getcwd, since we now depend on a reliable one.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Renamed from
        GL_FUNC_GETCWD_PATH_MAX for consistency.  All uses changed.
        Use the _ONCE methods, for efficiency.
        Check for fcntl.h.  In test program, include <errno.h>
        and <fcntl.h> if available.  Remove old K&R cruft from
        test program.  Check for common errors in GNU/Linux,
        OpenBSD, and Solaris.  Just set gl_cv_func_getcwd_path_max;
        don't do AC_LIBOBJ, as that's getcwd.m4's job.
        * m4/getcwd.m4 (gl_FUNC_GETCWD_NULL): Renamed from
        AC_FUNC_GETCWD_NULL.  All used changed.  Change cache variable
        name accordingly.
        (gl_FUNC_GETCWD, gl_PREREQ_GETCWD): New macros.  Revamp to
        accommodate new getcwd.c.
        * m4/jm-macros.m4 (gl_MACROS): Don't require GL_FUNC_GETCWD_PATH_MAX.
        * m4/prereq.m4 (gl_PREREQ): Add gl_FUNC_MEMPCPY.
        * m4/xgetcwd.m4 (gl_XGETCWD): Replace with gl_FUNC_GETCWD, since
        that's all we need now.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * m4/argp.m4 (gl_ARGP): Require gl_GETOPT_SUBSTITUTE unconditionally:
        argp-parse.c depends on getopt internals, that means we should
        always use our getopt, to be on the safe side.
        * m4/getopt.m4 (gl_GETOPT): Check if GETOPT_H is already set, in
        order not to spoil the result of an eventual previous invocation
        of gl_GETOPT_SUBSTITUTE.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * lib/getopt_.h: Re-addition of __getopt_argv_const caused
        redefinition warnings. To avoid them, include the defines
        in `#if !defined __need_getopt ... #endif'. The only place
        where __getopt_argv_const is used is in definitions
        of getopt_long and getopt_long_only below, which are as well
        protected by `#ifndef __need_getopt'.
        [defined __GETOPT_PREFIX && !defined __need_getopt]: Undef
        __need_getopt after including <stdio.h> and <unistd.h> These
        headers might have defined it.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/utimens.m4 (gl_UTIMENS): Check for futimes function.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros.
        (futimens): New function, which uses futimes if available.
        (futimens, utimens): Support timespec==NULL, with same semantics
        as utime and utimens.
        * lib/utimens.h (futimens): New decl.

2004-11-23  Jim Meyering  <jim@meyering.net>

        * lib/getopt_.h: Remove trailing blanks.

2004-11-23  Jim Meyering  <jim@meyering.net>

        * lib/__fpending.c: Add comment.

2004-11-22  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/canonicalize (Depends-on): Add xreadlink.
        Problem reported by James Youngman.

2004-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getopt_.h (__GETOPT_CONCAT, __GETOPT_XCONCAT, __GETOPT_ID):
        New macros.
        (getopt, getopt_long, getopt_long_only, optarg, opterr, optind,
        optopt): Use them instead of invoking ## directly; otherwise, the
        symbols will be __GETOPT_PREFIXgetopt rather than rpl_getopt.

2004-11-19  Bruno Haible  <bruno@clisp.org>

        * lib/strtok_r.c: Move comments from here...
        * lib/strtok_r.h: ... to here.

2004-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Check for buggy calloc
        implementations that mishandle size_t overflow.

2004-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/realloc.c (rpl_realloc): Call 'free' if n==0, since realloc
        might fail.  Problem reported by Yoann Vandoorselaere.
        * lib/calloc.c (rpl_calloc): Defend against buggy calloc
        implementations that mishandle size_t overflow.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/canon-host (Depends-on): Add strdup.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/canon-host.m4 (gl_CANON_HOST): Check for getaddrinfo.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/canon-host.c: Include "strdup.h".
        (canon_host): Use getaddrinfo if available, so that IPv6 works.
        Use strdup instead of malloc/strcpy to duplicate strings.

        * lib/human.h (LONGEST_HUMAN_READABLE): Add 1 for space before unit.
        (human_space_before_unit): New constant.
        * lib/human.c (human_readable): Support it.

        * lib/xgetcwd.c: Include <limits.h>, for PATH_MAX.
        (xgetcwd): Set errno correctly when failing.
        Work around Solaris 9 bug: getcwd sets errno==ERANGE even though
        the failure is actually due to a PATH_MAX problem.

        Further getopt changes to make it more likely that glibc will
        buy the changes back.
        * lib/getopt.c (POSIXLY_CORRECT): New constant.
        (getopt): Use it, so to preserve glibc semantic
        * lib/getopt1.c (getopt_long, getopt_long_only): Arg is char * const *
        when compiling for libc.
        * lib/getopt_.h (__getopt_argv_const): Bring it back.
        (getopt_long, getopt_long_only): Use it.

        * lib/getopt.c (_getopt_initialize, _getopt_internal_r,
        _getopt_internal): New arg POSIXLY_CORRECT.  All callers changed.
        (getopt): Argv is now char * const *, as per standard.
        (_getopt_internal_r, _getopt_internal): Argv is now char **,
        not char *__getopt_argv_const *.
        * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
        _getopt_long_only_r): Likewise.
        * lib/getopt_.h (getopt, getopt_long, geopt_long_only): Likewise.
        * lib/getopt_int.h (_getopt_internal, _getopt_internal_r,
        _getopt_long_r, _getopt_long_only_r): Likewise.
        * lib/getopt_.h (__getopt_argv_const): Remove.
        (getopt): Argv is now char * const *, as per standard.

        * lib/getdate.y (tORDINAL): New token.
        (day, relunit): Allow it for relative times.
        (relative_time_table): Use tORDINAL for ordinals.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi (General date syntax): "next" is 1, not 2.
        Document that "second" isn't allowed as an ordinal number.

2004-11-16  Jim Meyering  <jim@meyering.net>

        * modules/closeout (Depends-on): Add fpending.

2004-11-15  Jim Meyering  <jim@meyering.net>

        * lib/closeout.c: Include "__fpending.h" once again.
        Include <stdbool.h>.
        (close_stdout): Don't fail just because stdout was closed initially,
        since some programs don't write to stdout in the normal course of
        operation (other than --version and --help), and we don't want this
        function to make e.g. `touch file >&-' fail.
        But do fail if it was closed and someone has tried to write to it.
        E.g., `printf foo >&-' must fail.

2004-11-13  Jim Meyering  <jim@meyering.net>

        * m4/jm-macros.m4: Do require gl_FUNC_FPENDING.

2004-11-12  Simon Josefsson  <jas@extundo.com>

        * config/srclist.txt: Add strtok_r.c, glibc bought our changes, but a
        small doc fix is still pending.

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * modules/strtok_r: New file.

        * MODULES.html.sh (Support for systems lacking POSIX:2001): Add
        strtok_r.

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * m4/strtok_r.m4: New file.

        * m4/getopt.m4: Replace opterr.

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * lib/strtok_r.h, strtok_r.c: New file.

2004-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE): Define __GETOPT_PREFIX instead
        of replacing opterr, getopt, etc.  This should handle the
        powerpc-apple-darwin5.5 problem recently noted by Simon Josefsson.

2004-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getopt_.h (__getopt_argv_const): New macro, to be used so that
        we can stop lying to compilers about the constness of argv when we
        are compiled outside glibc.
        (getopt, getopt_long, getopt_long_only): Use it.
        * lib/getopt.c (_getopt_initialize, _getopt_internal_r,
        _getopt_internal, getopt): Likewise.
        * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
        _getopt_long_only_r): Likewise.
        * lib/getopt_int.h (_getopt_internal, _getopt_internal_r,
        _getopt_long_r, _getopt_long_only_r): Likewise.

        * lib/getopt_.h [defined __GETOPT_PREFIX && !defined __need_getopt]:
        Include <stdlib.h> and <stdio.h>, and <unistd.h> if available.
        Then rename getopt to __GETOPT_PREFIX##getopt, and so forth for
        the other external symbols.
        (getopt) [!defined __GNU_LIBRARY]: Use prototype, not old-style
        declaration, since the above renaming now works around collisions.

2004-11-11  Jim Meyering  <jim@meyering.net>

        * lib/linebreak.c: Remove trailing blanks.
        * lib/alloca_.h: Likewise.
        * lib/acosl.c: Likewise.
        * lib/euidaccess.c: Likewise.
        * lib/allocsa.h: Likewise.

2004-11-10  Simon Josefsson  <jas@extundo.com>

        * MODULES.html.sh (Support for systems lacking POSIX:2001): Add
        getaddrinfo.

        * modules/getaddrinfo: New file.

2004-11-10  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/prereq.m4 (gl_PREREQ): Require gt_FUNC_SETENV.

2004-11-10  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mktime.c (SHR): New macro, which is a portable
        substitute for >> that should work even on Crays.
        (TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it.
        Problem reported by Mark D. Baushke in
        <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00071.html>.
        * lib/getdate.y (SHR): Likewise.
        (tm_diff): Use it.
        * lib/strftime.c (SHR): Likewise.
        (tm_diff): Use it.
        * lib/quotearg.c (struct quoting_options): Use unsigned int for
        quote_these_too, so that right shifts are well defined.  All uses
        changed.

2004-11-10  Jim Meyering  <jim@meyering.net>

        Ensure that no close failure goes unreported.
        * lib/closeout.c (close_stdout): Always close stdout.  I.e., don't
        return early when it seems there's nothing to flush.
        Don't include __fpending.h.

2004-11-10  Jim Meyering  <jim@meyering.net>

        * modules/closeout (Depends-on): Remove fpending.

2004-11-10  Jim Meyering  <jim@meyering.net>

        * m4/jm-macros.m4 (gl_MACROS): Don't require gl_FUNC_FPENDING.

2004-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/strftime.m4 (_gl_STRFTIME_PREREQS): Remove.  Move its body to
        gl_FUNC_STRFTIME.
        (gl_FUNC_STRFTIME): Use AC_CHECK_FUNCS_ONCE and AC_CHECK_HEADERS_ONCE
        and AC_REQUIRE when possible, to avoid duplicate checks.
        Check for <wchar.h>.

2004-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/strftime.c (DO_MULTIBYTE): Check for wchar.h, too.

2004-11-09  Bruno Haible  <bruno@clisp.org>

        * m4/sockpfaf.m4: New file.

2004-11-05  Bruno Haible  <bruno@clisp.org>

        * lib/readlink.c: Include stddef.h, needed for size_t on Woe32.
        Reported by Mark D. Baushke <mdb@cvshome.org>.

        2004-09-11  Bruno Haible  <bruno@clisp.org>
                * allocsa.valgrind: New file.
        2004-02-06  Bruno Haible  <bruno@clisp.org>
                * allocsa.h (sa_alignof): Define differently with HP-UX cc, to
                avoid a bug of this cc on HP-UX 10.20 dealing with enums.
                Reported by Christopher Seip <chris.seip@hp.com>.

2004-11-04  Bruno Haible  <bruno@clisp.org>

        * modules/allocsa (Files): Add lib/allocsa.valgrind.
        (Makefile.am): Distribute it.

2004-11-03  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xreadlink.c (xreadlink): AIX and HP-UX readlink return -1
        with errno == ERANGE if the buffer is too small.
        Problem reported by Mark D. Baushke.

2004-11-03  Albert Chin  <china@thewrittenword.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        * m4/uint32_t.m4 (gl_AC_TYPE_UINT32_T): When determining uint32_t
        equivalent, substitute $ac_type for equivalent type rather than
        blindly using uint32_t *always* which won't work if uint32_t is not
        available.  Define _UINT32_T to work around typedef of uint32_t if
        <sys/sched.h>, <pthread.h>, or <semaphore.h> used on Solaris
        2.5.1.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/jm-macros.m4: Sync from coreutils.
        (gl_MACROS): Check for mbrlen, for pathchk.
        (gl_CHECK_ALL_TYPES): Require AC_TYPE_MBSTATE_T, for pathchk.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xreadlink.c (MAXSIZE): New macro.
        (xreadlink): Use it instead of SSIZE_MAX.  Ensure initial buffer
        size does not exceed MAXSIZE.  Avoid cast.
        As suggested by Mark D. Baushke in
        <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00009.html>,
        if readlink fails with buffer size just under MAXSIZE, try again
        with MAXSIZE.

2004-11-02  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Add mktime.c; glibc bought all our changes.

2004-11-02  Derek R. Price  <derek@ximbiot.com>
        and  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getdate.y [!TEST]: Include <stdio.h>, since we use sprintf now.
        (get_date): Overparenthesize to avoid GCC warning.

2004-11-02  Bruno Haible  <bruno@clisp.org>

        * m4/setenv.m4 (gt_FUNC_SETENV): Define VOID_UNSETENV if unsetenv()
        returns void.

2004-11-02  Bruno Haible  <bruno@clisp.org>

        * lib/setenv.h (unsetenv): Define as a macro if the system's unsetenv()
        function returns void.

        * m4/getpass.m4 (gl_PREREQ_GETPASS): Check for declarations of
        fflush_unlocked, flockfile, funlockfile, funlockfile,
        fputs_unlocked, putc_unlocked.

        * lib/getpass.c (fflush_unlocked, flockfile, funlockfile)
        (funlockfile, fputs_unlocked, putc_unlocked): Don't define if
        already declared.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/getdate (Files): Add doc/getdate.texi.
        (Depends-on): Add setenv, xalloc.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getdate.y: Add support for TZ="foo" within a date string.
        Fix some bugs near time_t boundaries.  Reject dates with
        out-of-range components, e.g., "Sept 31".
        Include <stdlib.h>, "setenv.h", "xalloc.h".
        (ISDIGIT_LOCALE): Remove; unused.
        Note that the TZ and time functions used here are not reentrant.
        (mktime_ok, get_tz): New functions.
        (TZBUFSIZE): New constant.
        (get_date): Parse leading TZ="foo".  Reject out-of-range components;.
        This requires that we sometimes generate our own TZ="XXX..." setting.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/getdate.texi: New file, from coreutils with modifications for
        the new TZ parsing.

2004-10-27  Derek R. Price  <derek@ximbiot.com>

        Reported by James Youngman in
        <http://lists.gnu.org/archive/html/bug-gnulib/2004-10/msg00199.html>.

2004-10-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getdate.y: Use Bison 1.875 features, and some minor
        code cleanups.  This change does not affect semantics.
        Don't include <stdlib.h>; no longer needed.
        Don't include unlocked-io.h; only the "#if TEST" code uses
        stdio, and performance isn't crucial there.
        (PC, YYLEX_PARAM, YYPARSE_PARAM): Remove; replaced by
        Bison 1.875 features as described below.
        All uses of "PC." replaced by "pc->".
        (YYSTYPE): Add a forward declaration.
        (yylex, yyerror): Use full prototypes in forward decls.
        Use "%pure-parser" rather than obsolescent "%pure_parser".
        Use %parse-param and %lex-param instead of obsolescent
        YYPARSE_PARAM and YYLEX_PARAM.
        (meridian_table, month_and_day_table, time_units_table,
        relative_time_table, time_zone_table, military_table,
        lookup_zone, lookup_word, get_date):
        Use NULL instead of 0 where appropriate.
        (to_hour): Avoid abort (), to avoid a dependency on
        stdlib.h.
        (yyerror, yylex): Now accepts parser_control * arg.
        (main) [TEST]: Use '\0' rather than 0 for char.

2004-06-01  Paul Eggert  <eggert@cs.ucla.edu>
        and  Jim Meyering  <jim@meyering.net>

        Merge from coreutils CVS.

        * lib/stat-macros.h: New file, with contents from file-type.h
        and coreutils' system.h.
        * lib/file-type.c: Include "stat-macros.h".
        * lib/file-type.h (file_type): Move all macro definitions to new file,
        stat-macros.h.

        * lib/chown.c (rpl_chown) [CHOWN_FAILS_TO_HONOR_ID_OF_NEGATIVE_ONE]:
        Wrap old code with this conditional.
        [CHOWN_MODIFIES_SYMLINK]: Try to work around a chown
        function that does not dereference symlinks.
        * lib/lchown.c (lchown) [CHOWN_MODIFIES_SYMLINK]: Just call chown.

        * lib/xreadlink.c: Include xreadlink.h first, to catch .h file
        dependency problems.
        (xreadlink): Accept new arg SIZE, for efficiency.
        All decls and uses changed.
        * lib/xreadlink.h: Include <stddef.h>, for size_t.

        * lib/.cppi-disable: Add alloca_.h, allocsa.h, exit.h, getndelim2.h,
        gettext.h, localcharset.h, strdup.h, strndup.h, strtoul.c, time_r.h.

        * lib/.cvsignore: Add alloca.h, fnmatch.h, poll.h, stdbool.h,

2004-06-01  Jim Meyering  <jim@meyering.net>

        * m4/calloc.m4: New file.

2004-05-31  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/stdbool.m4 (AC_HEADER_STDBOOL): Detect _Bool bug in HP aC++/ANSI
        C B3910B A.05.55 [Dec 04 2003].  Problem reported by Jim Meyering.
        Also, fix a typo in a diagnostic.

2004-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Do not require AC_FUNC_MALLOC
        or AC_FUNC_REALLOC.

2004-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/xmalloc.c (HAVE_MALLOC, HAVE_REALLOC): Do not require these
        macros to be defined.
        (xnmalloc_inline, xnrealloc_inline, xcalloc): Do not die if
        the allocator returns NULL because the requested size is zero.

2004-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/malloc/obstack.c (_obstack) [defined _LIBC]: Bring back this
        var.  Add comment explaining why libc still defines it.  This
        merges the following patch from glibc:
        http://sources.redhat.com/ml/libc-alpha/2004-05/msg00157.html

2004-05-20  Andreas Schwab  <schwab@suse.de>

        * m4/free.m4: Replace free if it not known to work, not the other
        way round.

2004-05-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/obstack.c (_obstack): Remove unused variable.  It hasn't been
        present in glibc since revision 1.1 of this file.
        * lib/obstack.h (_obstack_free, obstack_1grow, obstack_1grow_fast,
        obstack_alignment_mask, obstack_alloc, obstack_base,
        obstack_blank, obstack_blank_fast, obstack_chunk_size,
        obstack_copy, obstack_copy0, obstack_finish, obstack_grow,
        obstack_grow0, obstack_init, obstack_int_grow,
        obstack_int_grow_fast, obstack_make_room, obstack_memory_used,
        obstack_next_free, obstack_object_size, obstack_ptr_grow,
        obstack_ptr_grow_fast, obstack_room): Remove declarations of
        nonexistent functions.

2004-05-18  Karl Berry  <karl@gnu.org>

        * config/srclist.txt: break link for vasnprintf.c.

2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        Port obstack to the AS/400, where pointers are 16 bytes wide and
        you cannot cast an integer to a valid pointer.  This patch is
        currently waiting to be integrated into glibc; see
        <http://sources.redhat.com/ml/libc-alpha/2004-05/msg00073.html>.

        * lib/obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove.
        All uses of __INT_TO_PTR (PTR_TO_INT ...) replaced by __PTR_ALIGN.
        (__BPTR_ALIGN, __PTR_ALIGN): New macros.
        (struct obstack): temp member is now a union of a pointer and
        an integer, instead of an integer.  All integer uses changed.
        This does not affect the physical layout of struct obstack,
        except on hosts (like the AS/400) where the size or alignment of
        void * is greater than that of ptrdiff_t.
        (obstack_finish) [! (defined __GNUC__ && defined __STDC__ &&
        __STDC__)]: Store temporary in pointer member of union, not
        integer member.
        * lib/obstack.c: Include <stddef.h>, for offsetof.
        (struct fooalign): Remove; it doesn't need a name.
        (union fooround): Change double to long double, and add void *.
        (DEFAULT_ALIGNMENT): Use offsetof to compute.
        (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Now an enum constant,
        not a macro.  Hence the values are always int; so remove all
        casts-to-int in uses.

2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        * config/srclist.txt: Break link for argp-help.c and argp-parse.c until
        we can get this patch merged into glibc.

2004-05-17  Derek R. Price  <derek@ximbiot.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        * m4/argp: Depend on alloca.

2004-05-17  Derek R. Price  <derek@ximbiot.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        * lib/argp-help.c, argp-parse.c: Assume <alloca.h> rather than
        freecoding.

2004-05-17  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (VASNPRINTF): Correctly handle the case of a
        precision that consists of a '.' followed by an empty digit string.
        Patch by Tor Lillqvist <tml@iki.fi>.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/alloca.m4 (gl_FUNC_ALLOCA): Define HAVE_ALLOCA_H always,
        for backward compatibility with older code.  We need our own
        alloca.h if _AIX is defined.  Define HAVE_ALLOCA if we discover
        it under some other name, and our alloca.h will define it.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>
            Derek Price  <derek@ximbiot.com>

        * lib/alloca.c: Include <alloca.h>, to get our interface.
        * lib/alloca_.h: Use __alloca on AIX, so that we don't have to
        include <alloca.h> first.  Use C89 prototype for alloca; this
        requires including <stddef.h> for size_t.  Use extern "C" if C++.
        Use #elif for simplicity, since we can assume C89 now.
        Don't try to source the system alloca.h since it will not be found
        and to prevent recursively including its replacement.
        * lib/fnmatch.c: Include <alloca.h> instead of opencoding.
        * lib/regex.c: Likewise.

2004-05-16  Derek Price  <derek@ximbiot.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        getline cleanup.  This changes the getndelim2 API: both order of
        arguments, and meaning of delim2 (now uses EOF, not 0, to indicate
        no delimiter).

        * lib/getline.c: Don't include stddef.h or stdio.h, since our
        interface does that.
        (getline): Always use getdelim, so that we don't have two
        copies of this code.
        * lib/getndelim2.c: Include <limits.h>, <inttypes.h>, <stdint.h>
        if available.
        (PTRDIFF_MAX, SIZE_MAX, SSIZE_MAX): Define if not defined.
        (GETNDELIM2_MAXIMUM): New macro.
        (getndelim2): Reorder arguments.  delim==EOF now means no delimiter,
        instead of the old practice of delim2==0.  All callers changed.
        Return -1 on overflow, instead of returning junk.
        Do not set *linesize unless allocation succeeds.
        * lib/getndelim2.h: Do not include stddef.h; no longer needed, now
        that we include sys/types.h.
        * lib/getnline.h: Likewise.
        * lib/getndelim2.h (GETNLINE_NO_LIMIT): New macro.
        (getndelim2): Reorder arguments.
        * lib/getnline.c (getnline, getndelim):
        Don't discard the NMAX argument.
        (getnline): Invoke getndelim, to avoid code duplication.
        * lib/getnline.h (GETNLINE_NO_LIMIT): New macro, used instead
        of (size_t) -1 by callers of the getnline family.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/gettime.m4 (gl_GETTIME): Require gl_TIMESPEC.
        Check for gettimeofday.
        * m4/settime.m4 (gl_SETTIME): Require gl_TIMESPEC.
        Check for settimeofday, stime.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/nanosleep.c (suspended): Change its type from int to
        sig_atomic_t volatile.
        (first_call): Make it private to rpl_nanosleep, and have it
        be zero initially as that's a bit faster.
        (my_usleep): Round up fractional times instead of truncating them,
        as this is the usual meaning for 'sleep'.

        * lib/gettime.c (gettime): Fall back on `time' if `gettimeofday'
        doesn't work.
        * lib/settime.c: Include <unistd.h>, for stime (on Solaris 8, anyway).
        (ENOSYS): Define if not defined.
        (settime): Fall back on stime if it exists and settimeofday fails.
        But don't bother with fallbacks if a method fails with errno == EPERM.

2004-05-11  Jim Meyering  <jim@meyering.net>

        Prior to this change, the save_cwd caller required read access to the
        current directory on most systems (ones with the fchdir function).

        * lib/save-cwd.c (save_cwd) [HAVE_FCHDIR]: If opening `.' read-only
        fails, try write-only, and finally, resort to using xgetcwd.

2004-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/obstack.c, obstack.h: Import changes from libc.

2004-04-28  Bruno Haible  <bruno@clisp.org>

        * lib/findprog.c (find_in_path): Treat Cygwin like Windows, since it
        also implicitly appends .exe to executables.
        * lib/localcharset.c (ISSLASH): Treat Cygwin like Windows, since it now
        accepts Windows pathnames.
        * lib/pathname.h (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN):
        Treat Cygwin like Windows, since it now accepts Windows pathnames.
        * lib/progreloc.c (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN):
        Treat Cygwin like Windows, since it now accepts Windows pathnames.
        Reported by Derek Robert Price <derek@ximbiot.com>.

2004-04-21  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (localcharset.c): break sync.

2004-04-20  Paul Eggert  <eggert@twinsun.com>

        * m4/host-os.m4: Add a copyright notice.

2004-04-20  Jim Meyering  <jim@meyering.net>

        * m4/dirfd.m4 (gl_FUNC_DIRFD): Rename from UTILS_FUNC_DIRFD.
        Don't emit trailing blanks.
        Also rename jm_-prefixed variables to have gl_ prefix.

        * m4/host-os.m4 (gl_HOST_OS): Rename from UTILS_HOST_OS.
        Also rename jm_-prefixed variables to have gl_ prefix.

        memory when realloc fails.

2004-04-19  Jim Meyering  <jim@meyering.net>

        * m4/readutmp.m4 (gl_PREREQ_READUTMP): Require gl_FUNC_FREE,
        now that readutmp.c may call `free (0)'.

2004-04-19  Bruno Haible  <bruno@clisp.org>

        * m4/mbrtowc.m4: Change jm_ to gl_ in cache variables as well.

        coreutils' stat program.
        (gl_PREREQ): Don't require jm_PREREQ_STAT.

2004-04-11  Paul Eggert  <eggert@twinsun.com>

        * lib/inttostr.h: Include <limits.h> unconditionally, since we assume
        C89.
        (CHAR_BIT): Remove, since we assume C89.
        Include <stdint.h> if available, as per current Autoconf CVS advice.

2004-03-31  Jim Meyering  <jim@meyering.net>

2004-03-30  Paul Eggert  <eggert@twinsun.com>

        Merge from coreutils.

        * m4/inttostr.m4: New file.
        * m4/getdate.m4 (gl_GETDATE): Remove time-related stuff.
        Require AM_STDBOOL_H and gl_TIMESPEC instead.
        Require gl_CLOCK_TIME.
        * m4/clock_time.m4 (gl_CLOCK_TIME): Require AC_GNU_SOURCE.

2004-03-30  Paul Eggert  <eggert@twinsun.com>

        * lib/cloexec.h, cloexec.c (set_cloexec_flag): Return int
        not bool, to be more consistent with Unix conventions.
        Suggested by Bruno Haible.

        Merge from coreutils.

        * lib/imaxtostr.c, lib/inttostr.c, lib/inttostr.h, lib/offtostr.c:
        * lib/umaxtostr.c: New files.

        * lib/getdate.h: Include stdbool.h, and timespec.h instead of
        the usual <time.h> dance.
        (get_date): Change signature to support fractional time stamps.
        All callers changed.
        * lib/getdate.y: Include "getdate.h" first, as we can now
        assume C89 and don't need to worry about 'const'.
        Similarly, include "unlocked-io.h" near start, not in middle.
        Include <limits.h>.
        (textint.value): Use long int rather than int.
        (textint.digits): Use size_t rather than int.
        (BILLION, LOG10_BILLION): New constants.
        (parser_control): New member rel_ns.  Members day_ordinal,
        time_zone, month, day, hour, minutes, rel_year, rel_month,
        rel_day, rel_hour, rel_minutes, rel_seconds
        are now long int, not int.  Member seconds is now struct timespec,
        not int.  New member timespec_seen.  Members dates_seen, days_seen,
        local_zones_seen, rels_seen, times_seen, zones_seen are now size_t,
        not int.
        (%union.intval): Now long int, not int.
        New member timespec.
        (tSDECIMAL_NUMBER, tUDECIMAL_NUMBER): New tokens.

        (spec): Now is a timespec or an item list.
        (timespec, items): New nonterminals.
        (time, rel, relunit, number, get_date):
        Add support for fractional seconds.
        (time): Fix bug: seconds weren't cleared in "00:00 +0000" syntax.
        (gmtime, localtime, mktime): Remove decls; not needed with C89.
        (to_hour): First arg is now long int, not int.
        (to_year): Returns long int, not int.
        Don't treat year -70 like 70.
        (tm_diff): Returns long int, not int.
        (lookup_word): Use bool instead of int when appropriate.
        (yylex): Use size_t for count, not int.
        Detect overflow when parsing large integer constants.
        Add support for fractions.
        (get_date): Make pointers 'const' if possible.
        Use more-portable code to detect integer overflow.
        (main) [TEST]: Adjust to above changes.  Test for localtime failure.
        Don't use ctime; it's not reliable if the year has >4 digits.

        * lib/human.c (humblock): Inspect BLOCKSIZE if BLOCK_SIZE isn't set.
        This is for compatibility with BSD.

        * lib/timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP): Define.
        (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
        From coreutils' system.h.

        * lib/userspec.c: Don't include "posixver.h".
        (parse_user_spec): Fall back on USER.GROUP parsing, regardless
        of POSIX version, as POSIX 1003.1-2001 allows that behavior as a

        that was always nonzero if a string was nonnull.

2004-03-30  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.

        Avoid a configure-time warning about sys/ucred.h on OSF V4.0.
        * m4/ls-mntd-fs.m4: Test for sys/ucred.h separately, since
        on some systems one must include <grp.h> before it.
        Reported by Christian Krackowizer.

2004-03-30  Jim Meyering  <jim@meyering.net>

        * m4/realloc.m4: Remove file, since now it does no more than

        the `configure.ac' section of module/realloc.
        * m4/malloc.m4: Likewise, but for AC_FUNC_MALLOC.

        depend on (defined _SC_PAGESIZE).  However, it does depend on
        HAVE_STRUCT_SIGACTION_SA_SIGACTION; this last change fixes a bug
        first reported by Jason Andrade in
        <http://mail.gnu.org/archive/html/bug-textutils/2003-03/msg00027.html>.

        (segv_handler): If ! HAVE_XSI_STACK_OVERFLOW_HEURISTIC, assume
        that every segmentation violation is a stack overflow.  (Ouch!)
        See Debian bug 136249 (still outstanding) for more info about why
        HAVE_XSI_STACK_OVERFLOW_HEURISTIC fails on Linux kernels.

        On systems without utime and without a utimes function capable of

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (alloca): Remove fallback definition.
        (freea): Remove definition.
        (VASNPRINTF): Use alloca only for small sizes, say <= 4000 bytes.
        Reported by Paul Eggert.

2003-11-16  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        Protect against address arithmetic overflow.
        * lib/printf-args.h: Include stddef.h.
        (arguments): Change type of field 'count' to size_t.
        * lib/printf-args.c (printf_fetchargs): Use size_t instead of
        'unsigned int' where appropriate.
        * lib/printf-parse.h: Include sys/types.h.
        (char_directive): Change type of *arg_index fields to ssize_t.
        (char_directives): Change type of fields 'count', max_*_length to
        size_t.
        * lib/printf-parse.c: Include sys/types.h and xsize.h.
        (SSIZE_MAX): Define fallback value.
        (PRINTF_PARSE): Use size_t instead of 'unsigned int' and ssize_t
        instead of 'int' where appropriate. Check a_allocated, d_allocated
        against overflow. Reject %m$ argument numbers > SSIZE_MAX + 1.
        * lib/vasnprintf.c: Include xsize.h.
        (VASNPRINTF): Use size_t instead of 'unsigned int' where appropriate.
        Check alloca, malloc, realloc, ENSURE_ALLOCATION arguments against
        overflow. Avoid wraparound when converting a width or precision from
        decimal to binary.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        Update from GNU gettext.
        * lib/printf-parse.c: Generalize to it can be compiled for wide
        strings.
        (PRINTF_PARSE, CHAR_T, DIRECTIVE, DIRECTIVES): New macros.
        * lib/vasnprintf.c: Generalize to it can be compiled for wide strings.
        (VASNPRINTF, CHAR_T, DIRECTIVE, DIRECTIVES, PRINTF_PARSE, USE_SNPRINTF,
        SNPRINTF): New macros.
        Don't include <alloca.h> if the file is used inside libintl.
        (local_wcslen): New function, for Solaris 2.5.1.
        (VASNPRINTF): Use it instead of wcslen.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h (xmax): New function.
        (xsum, xsum3, xsum4): Declare as "pure" functions.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc (Files): Undo latest change, since xalloc.h
        no longer needs SIZE_MAX or PTRDIFF_MAX.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_PREREQ_XALLOC): Do not require gl_SIZE_MAX or
        gl_PTRDIFF_MAX.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.c (__xstrtol): Remove "break" immediately after
        "return", to pacify some unknown compiler.  Problem reported
        by Joerg Schilling.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h: Do not include <limits.h> or <stdint.h>.
        (xalloc_oversized): Use sizeof (ptrdiff_t) and sizeof (size_t) for
        the heuristic, rather than PTRDIFF_MAX and SIZE_MAX.  This
        heuristic is just as accurate as far as we know, and it removes a
        dependency on size_max.m4 and ptrdiff_max.m4.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * modules/xsize (Files): Add m4/size_max.m4.
        * modules/xalloc (Files): Add m4/size_max.m4, m4/ptrdiff_max.m4.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * m4/size_max.m4: New file.
        * m4/ptrdiff_max.m4: New file.
        * m4/xsize,m4 (gl_XSIZE): Require gl_SIZE_MAX.
        * m4/xalloc.m4 (gl_PREREQ_XALLOC): New macro.
        (gl_XALLOC): Invoke it.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h (SIZE_MAX): Remove fallback definition.
        * lib/xalloc.h: Include limits.h. Assume SIZE_MAX and PTRDIFF_MAX are
        defined.

2003-11-10  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): [! (defined PTRDIFF_MAX &&
        PTRDIFF_MAX < SIZE_MAX)]: Fix off-by-one error that would have
        rejected some allocations of exactly SIZE_MAX - 2 bytes.
        From Bruno Haible.
        [defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX]: Use SIZE_MAX,
        not (size_t) -1, since it's defined here.

2003-11-09  Karl Berry  <karl@gnu.org>

        * config/mkinstalldirs, depcomp, mdate-sh: update from automake.

2003-11-06  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h [HAVE_STDINT_H]: Include <stdint.h>.
        (xalloc_oversized) [! (PTRDIFF_MAX < SIZE_MAX)]:
        Reject sizes of exactly SIZE_MAX bytes.
        * lib/xreadlink.c: Include "xalloc.h" before checking whether SIZE_MAX
        is defined, since "xalloc.h" now defines SIZE_MAX on modern hosts.

2003-11-05  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h: Include limits.h, to avoid a possible collision with
        SIZE_MAX defined in <limits.h> on Solaris.

2003-11-04  Jim Meyering  <jim@meyering.net>

        * modules/sysexits: Use the `$(VAR)' notation for AC_SUBST'd
        variable names, rather than @VAR@.
        * modules/poll: Likewise.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * modules/xsize: New file.
        * modules/linebreak: Depend on xsize.
        * MODULES.html.sh (func_all_modules): Add xsize.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * m4/xsize.m4: New file.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * lib/xsize.h: New file.
        * lib/linebreak.c: Include xsize.h.
        (mbs_possible_linebreaks, mbs_width_linebreaks): Check malloc()
        argument for overflow.
        Suggested by Paul Eggert.

2003-11-03  Karl Berry  <karl@gnu.org>

        * config/config.{guess,sub}: update from config.

2003-11-03  Jim Meyering  <jim@meyering.net>

        * modules/userspec (lib_SOURCES): Add userspec.h.
        (Include): Add "userspec.h".
        Improve description.

2003-11-03  Jim Meyering  <jim@meyering.net>

        * lib/userspec.c: Include "userspec.h".
        * lib/userspec.h: New file.

2003-11-03  Bruno Haible  <bruno@clisp.org>

        * m4/wait-process.m4 (gl_WAIT_PROCESS): Also check for waitid.

2003-11-03  Bruno Haible  <bruno@clisp.org>

        * lib/wait-process.c (wait_process): Use waitid with WNOWAIT if
        available, to avoid (extremely rare) race condition.
        Suggested by Paul Eggert.

2003-11-02  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (vasprintf.c): sync broken, sigh.

2003-10-31  Paul Eggert  <eggert@twinsun.com>

        * lib/mountlist.h (struct mount_entry.me_type_malloced): New member.
        * lib/mountlist.c (SIZE_MAX): Define if not defined already.
        (read_filesystem_list): Set and use me_type_malloced.
        Use "sizeof *me" rather than "sizeof (struct mount_entry)" (or
        whatever the type happens to be), for brevity and consistency.
        Check for size calculation overflow on Alphas running OSF/1.

2003-10-31  Jim Meyering  <jim@meyering.net>

        * lib/hash.c: Include "xalloc.h" for use of xalloc_oversized.

        * lib/linebuffer.c: Include <string.h> for declaration of memset.

2003-10-30  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/vasprintf.c: Include <limits.h>, <stdlib.h>.
        (vasprintf): Fail if the resulting length doesn't fit in an 'int'.

2003-10-30  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/host-os.m4 (UTILS_HOST_OS): Change netbsd*-gnu pattern back to
        netbsd*-gnu*.  Suggested by Robert Millan.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * modules/group-member: Depend on stdbool.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_XALLOC): Undo previous change.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * m4/host-os.m4 (UTILS_HOST_OS): Resurrect netbsd*-gnu.  Add comments
        to it, and to knetbsd*-gnu and kfreebsd*-gnu.  Remove the '*' from
        after the 'gnu' in these cases.  This fixes some bugs in the
        previous change, and is based on suggestions by Robert Millan.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): Now a macro, not a function,
        so that it works even if SIZE_MAX < N.  Do not include <stdbool.h>;
        no longer needed.
        * lib/quotearg.c (quotearg_n_options): Use it.
        * lib/group-member.c: Include <stdbool.h>.
        (free_group_info): Arg is now const *; don't free arg.
        (get_group_info): Now returns bool and accepts struct group_info *,
        rather than returning a malloc'ed struct group_info *.
        All uses changed.  Check for overflow in internal size calculation.

        * lib/getusershell.c (readname): Simplify the code by using x2nrealloc
        rather than xmalloc/xrealloc.
        * lib/linebuffer.c (initbuffer, readlinebuffer): Simplify the code by
        using x2realloc rather than xmalloc/xrealloc.  Also, fix a C
        conformance bug: the old code used a pointer after freeing the
        storage that it addressed.
        * lib/hash.c (hash_initialize): Simplify the code by using
        xalloc_oversized rather than doing it by hand.
        * lib/getgroups.c (getgroups): Don't use xrealloc, since we don't need
        the buffer preserved.  Use free and xmalloc instead.
        * lib/quotearg.c (quotearg_n_options): Likewise.
        Use a simpler test for size overflow.  Don't use xalloc_oversized
        because unsigned int might be wider than size_t (!); this suggests
        that we should switch from unsigned int to size_t for slot numbers.

2003-10-28  Paul Eggert  <eggert@twinsun.com>

        * m4/host-os.m4 (UTILS_HOST_OS): Identify GNU/KFreeBSD and
        GNU/KNetBSD.  These implementations use glibc atop the FreeBSD and
        NetBSD kernels.  Requested by Richard Stallman.

2003-10-27  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (new_exclude): Use xzalloc rather than xmalloc
        to allocate the returned structure.  Do not allocate a subarray,
        as x2nrealloc will do that.
        (add_exclude): Use x2nrealloc to reallocate ex->exclude,
        instead of xnrealloc.
        (add_exclude_file): Use x2realloc instead of malloc + xnrealloc.

2003-10-27  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h: Better support for BeOS.

2003-10-26  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_XALLOC): Requore AC_C_INLINE, since xalloc.h
        now uses inline.

2003-10-26  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (xalloc_oversized): New static inline function, for
        callers that want to do their own size-overflow checking.  Include
        <stdbool.h>, since xalloc_oversized returns bool.
        * lib/xalloc.c (array_size_overflow): Remove.  All callers changed
        to use xalloc_oversized.

        Add two functions x2realloc, x2nrealloc, for programs that grow
        arrays dynamically by doubling their sizes.
        * lib/xalloc.h (x2realloc, x2nrealloc): New decls.
        * lib/xmalloc.c (x2nrealloc_inline, x2nrealloc, x2realloc):
        New functions.

        Port to C99 semantics for 'inline' of external functions.
        Bug reported by Bruno Haible.
        * lib/xmalloc.c (xnmalloc_inline): New static inline function,
        with the old contents of xnmalloc.
        (xnmalloc, xmalloc): Use it.
        (xnrealloc_inline): New static inline function,
        with the old contents of xnrealloc.
        (xnrealloc, xrealloc): Use it.

        * lib/alloc.c (alloca): xmalloc cannot return NULL, so don't test for
        that.

2003-10-26  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (COPYING.DOC): no longer available from
        /gd/gnuorg; don't know where the ultimate source is.

2003-10-25  Paul Eggert  <eggert@twinsun.com>

        Fix several address-calculation bugs in the hash modules,
        plus some minor code cleanup.

        * lib/hash.h: Include <stdbool.h>, for bool.
        * lib/hash.c: Don't include <stdbool.h>, since hash.h does it now.
        * lib/hash.h (Hash_hasher, hash_get_n_buckets, hash_get_n_buckets_used,
        hash_get_n_entries, hash_get_max_bucket_length,
        hash_get_entries, hash_do_for_each, hash_string, hash_initialize,
        hash_rehash): Use size_t rather than unsigned.
        * lib/hash.c (struct hash_table, hash_get_n_buckets,
        hash_get_n_buckets_used, hash_get_n_entries,
        hash_get_max_bucket_length, hash_table_ok, hash_print_statistics,
        hash_get_entries, hash_do_for_each, hash_string, is_prime,
        next_prime, hash_initialize, hash_rehash, hash_delete, hash_print):
        Likewise.
        (SIZE_MAX): Define if not defined.
        (hash_get_max_bucket_length, hash_table_ok, hash_lookup,
        hash_get_first, hash_get_next, hash_get_entries, hash_do_for_each,
        hash_print):
        Use const * when possible.
        (hash_string): Use (unsigned char) *P rather than *(unsigned char *) P.
        (check_tuning): Fix bug: if tuning parameters were very close to
        0 or 1, rounding errors could have caused subscript violations.
        (hash_initialize, allocate_entry, hash_print): Remove unnecessary cast.
        (hash_initialize): Add 'fail:' label
        to free table and return NULL, and use it to simplify code.
        Use calloc rather than clearing the storage ourself.
        (hash_initialize, hash_rehash): Check for arithmetic overflow in
        buffer size calculations.
        * lib/hash-pjw.h (hash_pjw): Use size_t, not unsigned.
        Include <stddef.h>, for size_t.
        * lib/hash-pjw.c (hash_pjw): Likewise.
        Switch to method described by Bruno Haible.
        Include <limits.h>, for CHAR_BIT.
        (SIZE_BITS): New macro.

2003-10-23  Paul Eggert  <eggert@twinsun.com>

        * m4/getline.m4 (AM_FUNC_GETLINE):
        Don't include getndelim2.o twice into LIBOBJS; this breaks on some
        hosts.  Problem reported by Derek Robert Price in
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-10/msg00092.html>.
        This patch can be withdrawn after Autoconf 2.58 is required for gnulib.
        * m4/getndelim2.m4 (gl_GETNDELIM2): Likewise.

2003-10-21  Paul Eggert  <eggert@twinsun.com>

        * lib/getndelim2.c (getndelim2): When size calculation overflows,
        ceiling the allocation at NMAX bytes rather than silently
        discarding input bytes before NMAX is reached.  This makes
        a difference only if NMAX exceeds SIZE_MAX / 2.

        * lib/obstack.c: Merge from glibc.
        [defined _LIBC]: Include <obstack.h>, not "obstack.h".
        Add libc_hidden_def (_obstack_newchunk).
        (_obstack_free) [! defined _LIBC]: Remove.
        [defined _LIBC]: Make a strong alias from obstack_free, rather than
        a clone of the function body.
        (fputs) [defined _LIBC && defined USE_IN_LIBIO]: Remove.
        [defined _LIBC && !defined USE_IN_LIBIO]: Include <libio/iolibio.h>.

        * lib/obstack.h: Indenting cleanup, to make it easier to merge with
        glibc.
        (obstack_grow, obstack_grow0): Remove unnecessary parentheses around
        arg to memcpy.

        * lib/obstack.h (obstack_1grow_fast): Properly parenthesize arg.
        (obstack_ptr_grow_fast, obstack_int_grow_fast):
        Don't use lvalue casts, as GCC plans to remove support for them
        in GCC 3.5.  Reported by Joseph S. Myers.  This bug
        was also present in the non-GCC version, indicating that this
        code had always been buggy and had never been widely used.
        (obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank):
        Use the fast variant of each macro, rather than copying the
        definiens of the fast variant; that way, we'll be more likely to
        catch future bugs in the fast variants.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * modules/wait-process: New file.
        * MODULES.html.sh (func_all_modules): Add wait-process.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * m4/wait-process.m4: New file.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * lib/wait-process.h: New file, from GNU gettext.
        * lib/wait-process.c: New file, from GNU gettext.

2003-10-19  Jim Meyering  <jim@meyering.net>

        * lib/vasnprintf.c (vasnprintf): Work around losing snprintf on
        HPUX 10.20.

2003-10-18  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from config.

2003-10-16  Paul Eggert  <eggert@twinsun.com>

        * lib/getgroups.c: Include <errno.h>, <stdlib.h>.
        (getgroups): First arg is int, not size_t.
        Don't let 'free' mangle errno.

2003-10-16  Paul Eggert  <eggert@twinsun.com>

        * README: Mention that gnulib assumes that (foo *) NULL + 0 == NULL.

2003-10-16  Karl Berry  <karl@gnu.org>

        * config/config.{guess,sub}: update from config.

2003-10-16  Jim Meyering  <jim@meyering.net>

        * lib/xmalloc.c: Include <string.h>, for declarations of memset and
        memcpy.

2003-10-15  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c: Do not include <inttypes.h> or <stdint.h>.
        (SIZE_MAX): Remove.
        (new_exclude, add_exclude_file): Initial size no longer needs to
        be a power of 2.
        (add_exclude, add_exclude_file): Use xnrealloc instead of rolling
        our own address arithmetic overflow checking.

        * lib/fnmatch.c (SIZE_MAX): Define if standard headers don't.
        (fnmatch): Do not alloca more than 2000 wide characters;
        instead, use malloc for large buffers.
        Check for address arithmetic overflow, and return -1
        with errno set to ENOMEM in that case.
        * lib/fnmatch_loop.c (ALLOCA_LIMIT): New macro.
        (NEW_PATTERN): Do not alloca more than 8000 bytes;
        instead, return -1.  Check for address arithmetic overflow.

2003-10-14  Paul Eggert  <eggert@twinsun.com>

        Handle invalid suffixes and overflow independently, so that
        callers can treat them independently as needed.  Fix some bugs in
        suffix handling, e.g., "100k@" was not diagnosed as an invalid
        suffix for a human-readable blocksize.  The major caller-visible
        change is the addition of a new
        LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating
        that both overflow and suffix chars were found.

        * lib/human.c (humblock): Don't check separately for invalid suffix
        char; that is xstrtoumax's job (now that its bug is fixed).
        * lib/xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined
        INTMAX_MAX]: New macros.

        TYPE_MAXIMUM): New macros.
        (bkm_scale, bkm_scale_by_power): Return strtol_error, not int.
        (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values
        if overflow occurs, as it's what __strtol does and it's more useful
        in practice.
        (__xstrtol): If __strtol reports some error other than ERANGE,
        reflect it to the caller as LONGINT_INVALID.  If it reports
        ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW
        | LONGINT_INVALID_SUFFIX_CHAR if both errors occur.

        * modules/fatal-signal: Add m4/sig_atomic_t.m4 to file list.

2003-10-14  Bruno Haible  <bruno@clisp.org>

        * m4/sig_atomic_t: New file, from GNU gettext.
        * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Require gt_TYPE_SIG_ATOMIC_T.

2003-10-14  Bruno Haible  <bruno@clisp.org>

        * lib/fatal-signal.h: Improved comments. Suggested by Paul Eggert.
        * lib/fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert.
        Also use volatile where needed.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc: Do not depend on 'exit'.  Depend on 'stdbool'.
        Change maintainer from Bruno Haible to 'all'.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Require AC_C_INLINE.

        (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate,
        and define in terms of the other primitives.
        * lib/xmalloc.c: Include stdbool.h; do not include exit.h.
        (SIZE_MAX): Define if not already defined.
        (array_size_overflow): New function.
        (xalloc_die): Abort instead of exiting if 'error' returns.
        (xnmalloc, xnrealloc, xzalloc, xclone): New functions.
        (xmalloc, xrealloc): Use them.
        (xcalloc): Check for address arithmetic overflow.
        * lib/xstrdup.c (xstrdup): Use xclone, since memcpy should be
        a bit faster than strcpy.

2003-10-10  Simon Josefsson  <jas@extundo.com>

        * modules/argp (Depends-on): Add restrict and strcase.

2003-10-10  Simon Josefsson  <jas@extundo.com>

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        Merge getpass from libc, plus a few fixes.

        * lib/getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1.
        Include <stdbool.h>.
        Include <stdio_ext.h> if HAVE_STDIO_H, otherwise define
        __fsetlocking to empty.
        [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but
        do include <bits/libc-lock.h>.
        Do not include <fcntl.h>; not needed.
        [_LIBC]: Include <wchar.h>.
        (NOTCANCEL_MODE): New macro.
        (flockfile, funlockfile) [_LIBC]: New macros.
        (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr)
        [!_LIBC]: New macros.
        (call_fclose): New function.
        (getpass): Use it.  Save tty stream separately; this simplifies the
        code and makes it more reliable if stdin happens to equal stdout.
        Invoke __fsetlocking on tty.
        Handle thread cancellation if needed.
        Namespace cleanup (use __tcgetattr, __getline).
        Use bool for Booleans.
        [USE_IN_LIBIO]: Handle wide streams.
        [!_LIBC]: Unconditionally do the fseek, since we don't know what
        stream might go where.

        * lib/unlocked-io.h: Include <stdio.h>, so that the caller
        doesn't have to include <stdio.h> before us.
        (clearerr_unlocked, feof_unlocked, ferror_unlocked,
        fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked,
        fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked,
        putc_unlocked, putchar_unlocked): Define to the unlocked counterpart
        if not declared, so that we can use getpass.c code from libc without
        rewriting it.
        (flockfile, ftrylockfile, funlockfile): New macros.

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        * modules/getpass: Depend on stdbool.

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        This lets translators provide better translations for the
        "Written by ..." part of --version output.
        * lib/version-etc.h: Include stdarg.h.
        (version_etc_copyright): Declare as readonly.
        (version_etc): Make this function variadic with a NULL-terminated list
        of author name strings.

        * lib/version-etc.c: Include stdarg.h, stdlib.h.
        (version_etc_copyright): Declare as readonly.

        authors or more.
        (version_etc): Make this function variadic. Call version_etc_va.
        Suggestion from Gary V. Vaughan.

        * lib/long-options.h (parse_long_options): Change prototype: the
        authors string is moved to the end and becomes variadic.
        * lib/long-options.c: Include stdarg.h.
        (parse_long_options): Make this function variadic, too.
        Call version_etc_va, not version_etc.

2003-09-28  Jim Meyering  <jim@meyering.net>

        * lib/error.c: Correct cpp indentation.

2003-09-27  Paul Eggert  <eggert@twinsun.com>

2003-09-27  Paul Eggert  <eggert@twinsun.com>

        * m4/free.m4: New file.

2003-09-27  Paul Eggert  <eggert@twinsun.com>

        * lib/minmax.h (MIN, MAX)
        [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]:
        Omit the special code that used __typeof__, since we worry that
        it could be more trouble than it's worth.  See:
        http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00090.html
        http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00095.html

        * lib/free.c: New file.

        * config/mkinstalldirs: update from automake.

2003-09-26  Paul Eggert  <eggert@twinsun.com>

        * lib/error.c (SIZE_MAX) [!defined SIZE_MAX]: Define.
        (error_tail): Do not loop, reallocating temporary buffer, since
        the output cannot contain more wide characters than the input
        contains bytes, the size must be big enough already.  This avoids
        one potential size overflow calculation.  Check for size overflow
        when calculating temporary buffer size.  Free temporary buffer
        when done, if it was allocated with malloc; this plugs a memory
        leak.  Remove casts from void * to pointers, that are no longer
        needed now that we're assuming C89 or better.

        Merge error changes from glibc.

        * lib/error.c, error.h: Update copyright notice header to match glibc.
        * lib/error.c [defined _LIBC]: Include <errno.h>, <bits/libc-lock.h>.
        (error, error_at_line) [defined _LIBC && defined __libc_ptf_call]:

        * lib/error.h: Prepend __ to parameter names.

2003-09-26  Jim Meyering  <jim@meyering.net>

        * lib/error.c (error_tail): Move some declarations
        into inner scope where the local variables are used.

2003-09-26  Bruno Haible  <bruno@clisp.org>

        * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Add comments about the AIX
        stpncpy().
        Don't define stpncpy through config.h; it's now done through stpncpy.h.

2003-09-26  Bruno Haible  <bruno@clisp.org>

        * lib/stpncpy.h (gnu_stpncpy): New declaration.

        the buffer associated with the argument.  Bug reported by
        Simon Josefsson.

2003-09-24  Paul Eggert  <eggert@twinsun.com>

        * README: Document assumptions that 'int' is at least 32 bits
        wide, that integer arithmetic is 2's complement without overflow,
        that there are no holes in integer values, that adding sizes of
        two nonoverlapping objects can't overflow, and that all-bits-zero
        yields scalar zero.  Fix spelling and capitalization typos.

2003-09-19  Karl Berry  <karl@gnu.org>

        Include <stdarg.h>, <stdlib.h>, <string.h> unconditionally.
        (VA_START): Remove; all uses changed to va_start.
        [! (HAVE_VPRINTF || HAVE_DOPRNT || _LIBC)]: Remove support for
        this case.
        (exit): Remove decl.

2003-09-08  Paul Eggert  <eggert@twinsun.com>

        * lib/getversion.c: Remove; was migrated to backupfile.c in 1997.
        getversion.c should have been removed then, but was accidentally
        preserved.

        * lib/utime.c [!HAVE_UTIMES_NULL]: Include <sys/stat.h>, <fcntl.h>.
        (utime_null): Fix typo: 'st' was sometimes called 'sb'.

2003-09-08  Karl Berry  <karl@gnu.org>

        * config/config.sub, config.guess, srclistvars.sh: update from savannah
                config, forget about prep.

        * config/depcomp, missing: update from automake.

2003-09-07  Paul Eggert  <eggert@twinsun.com>

        * modules/time_r: Depend on 'restrict'.  Fix from Simon Josefsson in
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-09/msg00028.html>.

        * m4/mktime.m4 (gl_PREREQ_MKTIME): Remove check for limits.h.
        * m4/timegm.m4 (gl_FUNC_TIMEGM): Assume that timegm is buggy if mktime
        is. Check for timegm declaration.
        (gl_PREREQ_TIMEGM): Require gl_FUNC_MKTIME.
        Do not check for gmtime_r.
        Replace mktime if __mktime_internal does not exist and if mktime
        hasn't been replaced already.

2003-09-06  Paul Eggert  <eggert@twinsun.com>

        * lib/time_r.c, lib/time_r.h: New files.

        * lib/mktime.c (my_mktime_localtime_r): Remove; all uses changed to
        __localtime_r.

        __gmtime_r.
        (my_strftime_localtime_r): Remove; all uses changed to __localtime_r.
        (__gtime_r, __localtime_r) [!HAVE_TM_GMTOFF]: New macros.
        Include <time_r.h>.

        * lib/timegm.c: Switch to glibc implementation, with the following
        changes:
        [defined HAVE_CONFIG_H]: Include <config.h>.
        [!defined _LIBC]: Include "timegm.h" rather than <time.h>.
        (__mktime_internal) [!defined _LIBC]: New decl.
        (__gmtime_r) [!defined _LIBC]: New macro and function.
        (timegm): Use a prototype, since gnulib assumes C89.
        Do not bother declaring tmp to be const, as it's not really usefu.
        * lib/timegm.h: Hoist "#include <time.h>" out of #ifdef.
        (timegm): Declare only if HAVE_DECL_TIMEGM.

2003-09-06  Paul Eggert  <eggert@twinsun.com>

2003-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/human.c (human_readable): Fix bug that rounded 10501 to 10k.
        Bug reported by Lute Kamstra in
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-09/msg00003.html>.

        * lib/getdate.y (relative_time_table): Use tDAY_UNIT for "tomorrow",
        "yesterday", "today", and "now" rather than tMINUTE_UNIT.  Of
        course with correspondingly smaller numbers for tomorrow and
        yesterday.  From Tadayoshi Funaba.  Originally installed into
        sh-utils on 1999-08-07, but the patch got lost (I guess during the
        coreutils merge?).

2003-08-31  Simon Josefsson  <jas@extundo.com>

        * modules/timegm: New file.
        * MODULES.html.sh (func_all_modules): Add timegm.

2003-08-31  Karl Berry  <karl@gnu.org>

        * lib/argp.h: update from libc.

2003-08-28  Bruno Haible  <bruno@clisp.org>

        * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH): Remove AC_DEFINE of fnmatch here.
        This avoids havoc on compilers for which '#define fnmatch rpl_fnmatch'
        followed by '#define fnmatch fnmatch_posix' gives an error.

2003-08-28  Bruno Haible  <bruno@clisp.org>

        * lib/binary-io.h: Undefine O_BINARY before defining it. This avoids a
        warning on QNX, which defines O_BINARY to 000000.

2003-08-27  Jim Meyering  <jim@meyering.net>

        * m4/mkstemp.m4: Require that the system mkstemp be able to create
        70 temporary files, not just 30.  Tru64 V4.0F's mkstemp function
        would fail after 32.  Reported by Danny Levinson.  Details here:
        http://mail.gnu.org/archive/html/bug-coreutils/2003-08/msg00124.html

2003-08-24  Bruno Haible  <bruno@clisp.org>

        * lib/binary-io.h: Include <stdio.h>, to avoid a compilation error when
        MSVC7 <stdio.h> is included later.

        * lib/progname.h: New file, from GNU gettext.
        * lib/progname.c: New file, from GNU gettext.
        * lib/progreloc.c: New file, from GNU gettext.

2003-08-19  Jim Meyering  <jim@meyering.net>

        * m4/lib-ld.m4: Revert yesterday's change, per Bruno's request here:
        http://mail.gnu.org/archive/html/bug-gnulib/2003-08/msg00155.html

2003-08-19  Bruno Haible  <bruno@clisp.org>

        * m4/xalloc.m4 (gl_PREREQ_XSTRDUP): Don't check for <string.h> any
        more.

2003-08-19  Bruno Haible  <bruno@clisp.org>

        * lib/xstrdup.c: Assume <string.h> exists.

2003-08-18  Paul Eggert  <eggert@twinsun.com>

        * modules/stdbool: Add BUILT_SOURCES.  Prefer $@ to target name
        in makefile rules.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * m4/getloadavg.m4: Use [\t ], not [ \t] (where \t is a literal TAB).
        * m4/lib-ld.m4: Likewise.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * lib/setenv.h: Indent nested cpp directive.

        like AC_GNU_SOURCE.
        * modules/extensions (configure.ac): Comment out the invocation of
        gl_USE_SYSTEM_EXTENSIONS.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        Merges from coreutils, etc.
        * m4/rpmatch.m4 (gl_PREREQ_RPMATCH): Insert ':' to prevent a syntax
        error in gl_FUNC_MATCH.  This fixes a bug I introduced on 2003-05-28.
        * m4/readlink.m4 (gl_PREREQ_READLINK): Renamed from gl_PREREQ_READLINE,
        fixing a typo.
        * m4/host-os.m4 (UTILS_HOST_OS): Add GNU/NetBSD, GNU/FreeBSD.
        * m4/hash.m4 (gl_HASH): Use AM_STDBOOL_H, not AC_HEADER_STDBOOL.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        Document merge from coreutils.
        * modules/alloca: Append $(ALLOCA_H) to BUILT_SOURCES.
        * modules/fnmatch: Append $(FNMATCH_H) to BUILT_SOURCES.
        * modules/utime: Add m4/utimes-null.m4.

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        * lib/regex.h, strdup.c, strtoll.c, strtoul.c: Do not normalize white
        space, undoing this 2003-08-12 change:
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-08/msg00080.html>

2003-08-16  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt: Get regex.h, strdup.c, strtoll.c,
        strtoul.c from libc, undoing this 2003-08-12 change:
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-08/msg00080.html>

2003-08-16  Jim Meyering  <jim@meyering.net>

        Merges from coreutils.
        * m4/readdir.m4 (GL_FUNC_READDIR): Change name to have GL_ (not jm_)
        prefix.  Adjust cache variables similarly.  Create 500 rather than
        just 300 files, to exercise bug on Darwin6.5, too.
        * m4/perl.m4 (jm_PERL): Use $am_missing_run, not undefined
        $missing_dir.
        * m4/jm-winsz1.m4: Require AC_SYS_POSIX_TERMIOS, not
        AM_SYS_POSIX_TERMIOS.
        Reported by mkc@mathdogs.com.
        Also change use of $am_cv_sys_posix_termios
        to $ac_cv_sys_posix_termios.  Reported by Andreas Schwab.
        * m4/getgroups.m4 (jm_FUNC_GETGROUPS): Rewrite to use AC_FUNC_GETGROUPS
        and (if needed) to call AC_LIBOBJ and to set GETGROUPS_LIB.
        * m4/fsusage.m4 [__GLIBC__]: GNU libc's statvfs stats each mount point
        in /proc/mounts until it finds one with matching device number.  This
        is unnecessary when the FILE argument *is* a mount point.  No stat call
        is necessary in that case.  So, disable the statvfs-testing code on
        systems with GNU libc.  Reported by Andrei Gaponenko via Tim Waugh
        as RedHat bug# 84846.
        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Limit stack size
        to 1MB, so as not to render systems with no stack size limit (e.g.,
        linux-2.2.x) unusable.  Suggestion and code from Bruno Haible.
        Include <unistd.h>.  On some systems,
        it is required for the definition of _SC_PAGESIZE.

2003-08-16  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/xstrtoimax.c: #else #if -> #elif.
        * lib/xstrtoumax.c: Likewise.

2003-08-16  Jim Meyering  <jim@meyering.net>

        * m4/utimes.m4 (gl_FUNC_UTIMES): New file.
        * m4/utimes.m4: Removed.

        * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Limit stack size
        to 1MB, so as not to render systems with no stack size limit (e.g.,
        linux-2.2.x) unusable.  Suggestion and code from Bruno Haible.
        Include <unistd.h>.  On some systems,
        it is required for the definition of _SC_PAGESIZE.

2003-08-16  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@cs.ucla.edu>

        Merges from coreutils, etc.

        * m4/jm-macros.m4 (AC_LANG_SOURCE(C)): New macro, undefine, then define
        using the latest version from cvs.  This avoids problems with #line
        directives using a vendor (Sun) compiler.
        (jm_MACROS): Bump prerequisite from 2.52g to 2.57.
        Don't set GETGROUPS_LIB here; now it's
        done via getgroups.m4's wrapper function.
        AC_SUBST OPTIONAL_BIN_PROGS, OPTIONAL_BIN_ZCRIPTS, and MAN here,
        rather than just in sh-util/configure.in, so that the
        now-shared-by-fileutils-and-textutils lib/Makefile.am are all the
        same.
        Use AC_CONFIG_LIBOBJ_DIR(lib) to tell the new
        AC_FUNC_GETLOADAVG where to find getloadavg.c.
        Require AC_FUNC_FTW, gt_INTTYPES_PRI, gl_CLOCK_TIME,
        UTILS_SYS_OPEN_MAX, GL_FUNC_GETCWD_PATH_MAX, GL_FUNC_READDIR,
        gl_FSUSAGE, gl_MOUNTLIST, AC_FUNC_CANONICALIZE_FILE_NAME.
        Remove code that is now done by the newly-required macros.
        Append $(EXEEXT) to DF_PROG.
        AC_LIBOBJ fchdir-stub if fchdir doesn't exist; similarly for fchown.
        Do not invoke or require the following here,
        since prereq.m4 or some gnulib .m4 now does this for us:
        gl_REGEX, UTILS_FUNC_MKDIR_TRAILING_SLASH, jm_BISON, gl_FUNC_MKTIME,
        jm_FUNC_LSTAT, jm_FUNC_STAT, jm_FUNC_REALLOC, jm_FUNC_MALLOC,
        jm_FUNC_NANOSLEEP, jm_FUNC_READDIR, jm_FUNC_MEMCMP,
        jm_FUNC_GLIBC_UNLOCKED_IO, AC_FUNC_FNMATCH_GNU, jm_FUNC_PUTENV,
        jm_AC_PREREQ_XSTRTOUMAX, jm_AC_PREREQ_XSTRTOIMAX,
        AC_FUNC_ERROR_AT_LINE, jm_FUNC_GNU_STRFTIME, AC_FUNC_VPRINTF,
        vb_FUNC_RENAME, UTILS_FUNC_MKSTEP, jm_FUNC_UTIME, AM_FUNC_GETLINE,
        AC_FUNC_OBSTACK.
        Do not replace the following functions, as this is now the job
        of some gnulib .m4: strcasecmp, strncasecmp, dup2, gethostname,
        getusershell, sig2str, strcspn, stpcpy, strstr, strtol, strtoul
        strpbrk, euidaccess, memcmp, rmdir, rpmatch, strndup, strverscmp,
        atexit getpass, strdup, getpagesize.
        Replace 'raise'.
        Do not check for the following functions, as this is now the job
        of some gnulib .m4: bcopy, canonicalize_file_name, fchdir, ftime,
        getcwd, getmntinfo, resolvepath.  But check for sysctl, setreuid,
        setregid.
        (jm_CHECK_ALL_HEADERS): Do not check for fenv.h.
        Check for sys/sysctl.h.
        (jm_CHECK_ALL_TYPES): Do not require AC_STRUCT_TM, AC_STRUCT_TIMEZONE,
        jm_CHECK_TYPE_STRUCT_TIMESPEC.  Invoke gt_TYPE_SSIZE_T instead
        of checking for ssize_t ourselves.

        * m4/prereq.m4 (jm_PREREQ): Don't invoke macros; AC_REQUIRE them.
        Require every macro that gnulib/modules/* suggests for us.
        (jm_PREREQ_ADDEXT): New macro.
        (jm_PREREQ_STAT): Check for 'struct statfs' on Ultrix 4.4.
        Require jm_AC_TYPE_LONG_LONG instead of invoking it.

        * m4/physmem.m4 (gl_SYS__SYSTEM_CONFIGURATION): New macro.
        (gl_PHYSMEM): Use it.
        Also check for `table' function.
        Check for new headers and functions.
        Add check for sys/sysmp.h.
        With suggestions from Kaveh Ghazi.
        Ignore headers that are present but cannot be compiled.  This
        avoids spurious warnings on Solaris 9 sparc with Forte Developer 7
        C 5.4.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        Document merge from coreutils.
        * modules/userspec: Depend on posixver.
        * modules/strftime: Depend on tzset.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        * lib/config.charset, ref-add.sin, ref-del.sin: Use three spaces,
        rather than tab, after '#' in shell-script copyright notices.
        Suggested by Bruno Haible.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Use three spaces, rather than tab, after '#'
        in shell-script copyright notices.  Suggested by Bruno Haible.
        Remove unnecessary parenthesization in regular expression.

2003-08-15  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/xgethostname.c: Include <stdlib.h>.
        (xghostname): Don't exit for anything other than memory-related
        failure; just return NULL.
        * lib/userspec.c: Include "posixver.h".
        (parse_user_spec): Accept `.' as a separator only
        in pre-POSIX-200112 mode.
        * lib/strtoimax.c: Use #elif rather than #else #if.
        * lib/strftime.c (my_strftime) [!_LIBC && HAVE_TZNAME && HAVE_TZSET]:
        Remove function, now that we can rely on a working tzset function.
        [!_LIBC]: Ensure that the required autoconf test has been run.
        [!defined _NL_CURRENT && HAVE_STRFTIME]:
        Use underlying_strftime for %r.
        * lib/sha.c: Merge in some clean-up and optimization changes from
        glibc.
        * lib/sha.c (sha_stream) [BLOCKSIZE]: Move definition to top of file.
        Ensure that it is a multiple of 64.
        Rearrange loop exit tests so as to avoid performing an
        additional fread after encountering an error or EOF.
        * lib/realloc.c: Update copyright date.

2003-08-15  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merge from coreutils.
        * lib/readutmp.h (HAVE_UTMPX_H): Undef if struct utmp has the ut_exit
        member but strut utmpx does not.  Needed for AIX 4.3.3.
        (UT_EXIT_E_TERMINATION, UT_EXIT_E_EXIT): Define.

2003-08-15  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@cs.ucla.edu>

        Merges from coreutils, etc.
        * m4/strftime.m4 (_jm_STRFTIME_PREREQS):
        Require gl_FUNC_TZSET_CLOBBER.
        * m4/readutmp.m4 (gl_READUTMP): Check for ut_exit.ut_exit,
        ut_exit.e_exit, ut_exit.ut_termination, and ut_exit.e_termination
        members.

2003-08-14  Paul Eggert  <eggert@twinsun.com>

        Help the merge from coreutils.
        * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): New macro.
        (AC_FUNC_GETTIMEOFDAY_CLOBBER): Use it.
        * m4/tzset.m4: Use it too.

2003-08-14  Paul Eggert  <eggert@twinsun.com>

        * modules/tzset: New file.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merges from coreutils.
        * modules/fnmatch: Use the `$(FNMATCH_H)' notation for AC_REPLACED
        variable names, rather than @FNMATCH_H@.
        * modules/alloca: Likewise for $(ALLOCA_H).

        * modules/fnmatch (fnmatch.h): Use `$@' in the commands, in place of
        the three copies of the literal target, `fnmatch.h'.
        * modules/alloca (alloca.h): Likewise.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * m4/tzset.m4: New file.
        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Move the
        MOUNTED_VMOUNT test to precede the MOUNTED_GETMNTENT1 tests, since
        otherwise, AIX 5.1 systems would end up using the latter.
        MOUNTED_GETMNTENT1 support is inadequate on such systems: 1) detecting
        whether a file system is remote doesn't work  2) the MOUNTED_VMOUNT
        code reports the HOSTNAME:/MOUNT_POINT, while the MOUNTED_GETMNTENT1
        code reports merely /MOUNT_POINT.  Reported by Mike Jetzer.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/obstack.h: Whitespace changes.
        * lib/mountlist.c: Remove anachronistic casts of xmalloc, xrealloc,
        and xcalloc return values.
        (read_filesystem_list) [MOUNTED_GETFSSTAT]:
        Use MNT_NOWAIT, rather than MNT_WAIT.  Otherwise, `df DIR' could
        hang on OSF/1 5.1 for DIR on both local and remote file systems.
        Reported by (and fix confirmed by) Nelson H. F. Beebe.
        (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

2003-08-14  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merges from coreutils, plus other fixes.
        * lib/physmem.c: Merge in portability changes from gcc/libiberty
        to support AIX, IRIX, Tru64, and Windows.  See the ChangeLog there
        for credits and details.  Thanks to Kaveh Ghazi for helping
        to keep these files in sync.
        (ARRAY_SIZE): Define it.
        (physmem_total, physmem_available): Add comments. From Kaveh Ghazi.

        Remove casts and duplicate code.
        * lib/md5.c: Include <string.h> and <stdlib.h> unconditionally.
        (memcpy): Remove definition.
        Merge in some clean-up and optimization changes from glibc.
        [BLOCKSIZE]: Move definition to top of file.
        Ensure that it is a multiple of 64.
        Rearrange loop exit tests so as to avoid performing an
        additional fread after encountering an error or EOF.
        * lib/md5.h (md5_uintptr): Define.
        * lib/makepath.c (CLEANUP_CWD): Report an error if we failed to
        return to the initial working directory.  Preserve errno
        for caller.
        * lib/idcache.c: Include "xalloc.h".
        (xmalloc, xrealloc): Remove decls.
        (getuser): Remove casts no longer required in C89.
        * lib/human.c: Include stdio.h, for sprintf.
        * lib/group-member.c: Include "xalloc.h".

        (get_group_info): Remove casts no longer required in C89.
        * lib/getusershell.c (readname): Remove casts no longer required in
        C89.
        * lib/gettimeofday.c (rpl_gmtime, rpl_tzset): New functions.
        * lib/getline.c: Whitespace fix, from coreutils.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * m4/exclude.m4 (gl_EXCLUDE): Require AC_C_INLINE, AC_HEADER_STDC.
        Check for isascii.

        * m4/gettext.m4, iconv.m4, intdiv0.m4, inttypes-pri.m4, lib-link.m4,
        lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4:
        Undo previous (whitespace-only) change.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c: Include <ctype.h>
        (IN_CTYPE_DOMAIN): New macro.

        (add_exclude_file): If LINE_END is a space, ignore trailing spaces
        and empty lines.

        Undo previous (whitespace-only) change.

2003-08-13  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Change update back to the old behavior,
        leaving whitespace alone.  Use one 'sed' command rather than a
        pipeline.
        (fixlicense): Now a variable, not a function.
        (remove_trailing_blanks): Remove.
        (fixfile): Don't invoke unexpand or cat, or remove trailing blanks.
        * config/config.guess, config.sub, install-sh, missing, texinfo.tex:
        Undo previous (whitespace-only) change.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4:
        Normalize leading white space and remove trailing white space.

        Merge from coreutils
        * m4/euidaccess.m4 (gl_FUNC_EUIDACCESS): Check for euidaccess decl.

        * m4/lib-ld.m4, lib-link.m4, lib-prefix.m4: Regenerate from gettext
        0.12.1.  These files are now being upgraded automatically by
        ../config/srclist-update.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        * lib/argp-help.c, argp-parse.c, config.charset, getopt.h:
        Normalize leading white space and remove trailing white space.
        * lib/ref-add.sin, ref-del.sin: Use '#' before empty line in copyright
        notice, as per ../config/srclist-update.

        Merge from coreutils.
        * lib/euidaccess.h: New file.
        * lib/euidaccess.c: Include it.
        * lib/.cppi-disable: Add printf-args.h, printf-parse.h, stdbool_.h,
        vasnprintf.h, vasprintf.h.  Remove strdup.c, gettext.h.
        * lib/regex.h, strdup.c, strtoll.c, strtoul.c: Normalize white space.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Add copyright notice.
        (remove_id_lines, remove_trailing_blanks): New constants.
        (fixfile): Use them to normalize spacing a bit in copied files.

        Normalize leading white space and remove trailing white space.

        * config/texinfo.tex: Sync with texinfo.

        * config/srclist.txt: Don't get regex.h, strdup.c, strtoll.c,
        strtoul.c from libc, to merge coreutils whitespace changes.

        * config/srclist.txt: Get the following m4 files from gettext:
        codeset.m4, gettext.m4, glibc21.m4, iconv.m4, intdiv0.m4,
        inttypes-pri.m4, lcmessage.m4, lib-ld.m4, lib-link.m4, lib-prefix.m4,

        wint_t.m4.

2003-08-12  Karl Berry  <karl@gnu.org>

        * config/srclist.txt: can't sync vasnprintf.c any more, changes have
        been made.

2003-08-11  Paul Eggert  <eggert@twinsun.com>

        * modules/gnu-source, m4/gnu-source.m4:
        Remove; we're assuming Autoconf 2.54 or later now.
        Suggested by Bruno Haible.
        * MODULES.html.sh (func_all_modules): Remove gnu-source.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF): Also check for wcslen.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (local_wcslen): New function, for Solaris 2.5.1.
        (vasnprintf): Use it instead of wcslen.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * lib/stdbool_.h (_Bool): Undo last change; instead use a negative enum
        value to ensure that _Bool promotes to int. Use #define for _Bool when
        using the Solaris C compiler. Adds comments suggested by Paul Eggert.

2003-08-10  Karl Berry  <karl@gnu.org>

        * lib/regex.h: update from libc (whitespace fix).

2003-08-09  Paul Eggert  <eggert@twinsun.com>

        Merge some files from coreutils.  These changes were
        originally made by Jim Meyering.
        * lib/acl.c: Include <sys/types.h> before <sys/stat.h>;
        many older Unixes require this.
        * lib/alloca.c (alloca): Remove cast to argument of free;
        no longer needed in C89.
        * lib/alloca_.h, regex.h: Fix white space to match
        what GNU indent does.

2003-08-09  Paul Eggert  <eggert@twinsun.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Change "\201" to "\371";
        apparently Emacs's Unicode mode got confused before my 2003-08-05
        checkin.

2003-08-08  Paul Eggert  <eggert@twinsun.com>

        * m4/extensions.m4: New file.

2003-08-07  Bruno Haible  <bruno@clisp.org>

        * modules/getndelim2 (Makefile.am): Add the files to EXTRA_DIST, not
        lib_SOURCES, because getndelim2.m4 now uses AC_LIBOBJ(getndelim2).

2003-08-07  Bruno Haible  <bruno@clisp.org>

        * m4/getndelim2.m4 (gl_GETNDELIM2): Use AC_LIBOBJ(getndelim2). This
        makes the module 'getndelim2' compatible with the module 'getline'.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Replace a single non-ASCII
        byte with "\201" to avoid glitches when editing that source file
        with multi-gnome-terminal.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * lib/bumpalloc.h: Remove.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        * MODULES.html.sh (func_all_modules): Remove bumpalloc.
        * modules/bumpalloc: Remove.

2003-08-04  Paul Eggert  <eggert@twinsun.com>

        * lib/getloadavg.c: Change copyright notice and spacing to conform to
        GNU coding style.

        Merge from coreutils.
        * lib/error.c [!USE_IN_LIBIO]: Omit this case; assume USE_IN_LIBIO is
        1. From glibc.
        * lib/getdate.y (date): Also accept dates like May-23-2003; suggestion
        from Karl Berry, implemented by Jim Meyering.
        * lib/getgroups.c: Include "xalloc.h" instead of declaring xalloc fns;
        from Dmitry V. Levin.
        Remove anachronistic cast of xrealloc.
        * lib/fnmatch_.h (__const): Remove.  Use 'const'.
        * lib/fnmatch_loop.c (NEW_PATTERN): Cast alloca return value to proper
        type. Otherwise, it wouldn't compile with at least /bin/cc on
        ymp-cray-unicos9.0.2.X.
        Combine two mostly-identical uses of alloca into one.
        Thanks to the Cray-Cyber project for access to a Cray Y-MP.

2003-08-04  Dave Love  <d.love@dl.ac.uk>

        [From Emacs.]

        * lib/getloadavg.c: Check `__unix' as well as `unix'.  Use #ifdef, not
        #if.  Check HAVE_LIBKSTAT as well as LOAD_AVE_TYPE.  Check
        F_SETFD, not FD_SETFD.  Use HAVE_STRUCT_NLIST_N_UN_N_NAME, not
        obsolete NLIST_NAME_UNION.
        [__GNU__]: Undef BSD and FSCALE.
        [!NLIST_STRUCT]: Remove conditional definition of NLIST_STRUCT.

2003-08-03  Paul Eggert  <eggert@twinsun.com>

        * lib/stdbool_.h (_Bool): Make it signed char, instead of
        an enum type, so that it's guaranteed to promote to int.  See:
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-07/msg00124.html>

2003-08-03  Karl Berry  <karl@gnu.org>

        * modules/getpass-gnu: New file.
        * MODULES.html.sh (func_all_modules): Add getpass-gnu.

2003-07-31  Bruno Haible  <bruno@clisp.org>

        * m4/getpass.m4 (gl_FUNC_GETPASS_GNU): New macro.

2003-07-24  Karl Berry  <karl@gnu.org>

        * config/missing: update from automake.

2003-07-24  Derek Robert Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/getline.h (getline, getdelim): Change return type to ssize_t.
        * lib/getline.c (getline, getdelim): Likewise.
        Remove _GNU_SOURCE define; now it's defined in config.h through
        m4/getline.m4.

2003-07-23  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * modules/xalloc (Depends-on): Add exitfail.
        * modules/xmemcoll: Likewise.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * lib/xalloc.h (XCALLOC, XREALLOC, CCLONE): Fix under- and
        over-parenthesization in macros.

        Sync with coreutils.

        * lib/xalloc.h (XMALLOC, XCALLOC, XREALLOC): Remove casts not
        required by C99.

        Use `exit_failure' for xalloc and xmemcoll instead of their own
        private exit-failure variables.
        * lib/xalloc.h (xalloc_exit_failure): Remove.
        * lib/xmalloc.c: Likewise.  Include exitfail.h.

        * lib/xmemcoll.h (xmemcoll_exit_failure): Remove.
        * lib/xmemcoll.c: Likewise.  Include exitfail.h.
        (xmemcoll): Use exit_failure instead of xalloc_exit_failure.

2003-07-20  Jim Meyering  <jim@meyering.net>

        * modules/closeout (Depends-on): Add exitfail.
        Suggestion from Bruno Haible.

2003-07-19  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-07-18  Paul Eggert  <eggert@twinsun.com>

        * lib/closeout.h (close_stdout_set_status, close_stdout_status):
        Remove.
        * lib/closeout.c: Likewise.  Include "closeout.h" right after config.h,
        to test that it can stand by itself.  Include "exitfail.h".
        Clients should set exit_failure instead.
        (EXIT_FAILURE): Remove; no longer needed.  Do not include <stdlib.h>.

2003-07-18  Bruno Haible  <bruno@clisp.org>

        * config/srclist-update: was running fixlicense twice, which caused
                texinfo.tex to be nullified for some reason.  Simplify,
                $gplsrc is no longer needed as far as I can see?

2003-07-14  Paul Eggert  <eggert@twinsun.com>

2003-07-11  Alexandre Duret-Lutz  <adl@gnu.org>

        Switch from LGPL to GPL.

2003-07-09  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt: Sort sublists.  Add
        $LIBCSRC/sysdeps/generic/strtoul.c. In comments, add more libc files
        that differ from gnulib for one reason or another; we'd like this list
        to be smaller but for now let's document what we have.

2003-07-08  Paul Eggert  <eggert@twinsun.com>

        * config/srclist-update: Port to POSIX 1003.1-2001 hosts by avoiding
        the use of GNU extensions.  Change "x=`eval echo $x`" to the shorter
        and sweeter "eval x=$x".
        * config/srclist.txt: Get lib/argp* from glibc.

2003-07-07  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c: Fix some boundary cases and remove need for floating
        point.

        Issue a compile-time diagnostic if time_t is floating point, or if
        two's complement arithmetic is not in effect, or if arithmetic
        right shift does not propagate the sign.  These assumptions were
        all in the original code but they weren't checked.

        (TIME_T_MIDPOINT, verify): New macros.
        (__isleap): Remove; it has integer overflow problems.
        (leapyear): New function, without those problems.
        (ydhms_tm_diff): Remove; splitting into two parts.
        (ydhms_diff): New function, containing the arithmetic part of
        the old ydhms_tm_diff function.  Issue a compile-time
        diagnostic if we are not using C99 integer division.
        Avoid casts when possible.
        (guess_time_tm): New function, containing the checking part of
        the old ydhms_tm_diff function.  Return the new value, rather than
        the difference between it and the old.  Accept a new argument T
        so that *T specifies the old value.  Check for overflow in the result.

        (__mktime_internal): Use a time_t offset, not a long int offset.
        This undoes the 2003-06-04 change, which is no longer needed now
        that we have better overflow checking.
        (localtime_offset): Likewise.

        (__mktime_internal): Avoid harmful overflow on hosts where time_t
        and long are 64-bit but int is only 32-bit.
        (ydhms_diff): Use long int to store year1 and yday1.
        Issue a compile-time diagnostic if long int is not wide enough.

        (__mktime_internal): Use long int to store adjusted year and yday.
        Use plain C rather than preprocessor commands, if that doesn't
        affect efficiency.
        Check for overflow (and try to repair) after each probe
        rather than checking only at the very end.  This avoids some bugs
        (e.g., southern hemisphere, behind GMT, and GMT offset at minimum time
        does not equal GMT offset at maximum time).
        Use integer to check for overflow rather than floating point; this
        is more portable to non-IEEE hosts, and is a tad faster.
        When we detect that we are oscillating between two values,
        don't check whether tm_isdst has the requested value, since
        we already know the answer.  When tm_isdst has the wrong value,
        use a different heuristic to find the right one, based on the
        extreme values actually observed in practice in tz2003a,
        rather than the (overly optimistic) "previous 3 calendar quarters".

        (not_equal_tm, print_tm, check_result): Use "const T" rather than
        "T const" to accommodate glibc style.
        (check_result): Use less-confusing report format.  "long" -> "long int.
        (main): Likewise.
        Don't loop if the iteration overflows time_t.
        Allow a negative step in the iteration.

        * lib/fsusage.c: Remove declaration of statfs.
        It conflicted with one from OSF/1 5.1 in <sys/mount.h>.

        * lib/posixtm.c: Include <stdbool.h> unconditionally.

2003-06-06  Jim Meyering  <jim@meyering.net>

        * lib/stdbool_.h: Renamed from stdbool.h.in.

2003-06-06  Jim Meyering  <jim@meyering.net>
            Bruno Haible  <bruno@clisp.org>

        * modules/stdbool: Reflect renaming: stdbool.h.in -> stdbool_.h.
        Adjust Makefile.am snippet not to redirect directly to target.
        Use $(STDBOOL_H) notation, not @STDBOOL_H@ for AC_REPLACE'd variables.

2003-06-05  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c (__mktime_internal): When resolving a tm_isdst
        mismatch, look in future quarters as well as past.  This fixes a
        bug when processing fall-backwards gaps immediately after a long
        period of daylight-saving time.

        * lib/mktime.c: Assume freestanding C89 or better.
        (HAVE_LIMITS_H): Remove.  Assume it's 1.
        (__P): Remove; not used.
        (CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them.
        (mktime, not_equal_tm, print_tm, check_result,
        main): Use prototypes.  Use const * where appropriate.
        (main): Fix typo in testing code that uncovered by above changes.
        (Local Variables): Remove -DHAVE_LIMITS_H from compile-command.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * m4/human.m4 (gl_HUMAN): Require AM_STDBOOL_H.  Check for
        locale.h, localeconv.  This merges changes from coreutils.

        * m4/mktime.m4 (AC_FUNC_MKTIME): New macro, taken from Autoconf CVS.
        It can be removed after the next Autoconf is released.
        * m4/exclude.m4 (gl_EXCLUDE): Don't check for sys/types.h; no loner
        needed.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * lib/mktime.c: Fix Debian bug 177940
        <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=177940>.
        (localtime_offset): Now long int, not time_t, because we want it
        to be guaranteed to be signed.  All uses changed.
        (__mktime_internal): If overflow would occur when adding offset,
        don't add it.

        Merge 'human' changes from coreutils.  Rewrite to support
        locale-specific notations like thousands separators.
        * lib/human.c: Simplify authorship notice.
        Include human.h immediately after config.h.
        <sys/types.h>, <stdio.h>: Do not include; no longer needed.
        <limits.h>: Do not include, since human.h does.
        (SIZE_MAX, UINTMAX_MAX): New macros.
        <strings.h>: Include if HAVE_STRINGS_H, not if !HAVE_STRING_H.
        <locale.h>: Include if HAVE_LOCALE_H and HAVE_LOCALECONV.
        (HUMAN_READABLE_SUFFIX_LENGTH_MAX): New macro.
        (power_letter): Renamed from suffixes.
        (generate_suffix_backwards): Remove.
        (adjust_value): Now takes int style (because of human.h changes)
        and long double value (for greater precision on some platforms).
        (group_number): New function.
        (human_readable): Use it.  Use integer options, not enum.
        Put the options before the sizes in the arg list.
        Support all the new options.
        The old human_readable function has been removed;
        use inttostr.h instead.
        (human_readable, default_block_size, humblock):
        Use uintmax_t, not int, for block sizes.
        (human_readable_inexact, block_size_types): Remove.
        (block_size_opts): New constant.
        (human_options): Renamed from human_block_size, with new signature
        that allows block sizes up to UINTMAX_MAX.  All callers changed.
        * lib/human.h: Add copyright and authorship notice.
        Include <limits.h> and <stdbool.h> unconditionally.
        (PARAMS): Remove.  All uses removed.
        (LONGEST_HUMAN_READABLE): Add support for thousands separator.
        (enum human_inexact_style): Remove tag; now a nameless enum.
        (human_floor, human_ceiling, human_round_to_even): Now have
        values 2, 0, 1 rather than -1, 1, 0.
        (human_group_digits, human_suppress_point_zero, human_autoscale,
        human_base_1024, human_SI, human_B): New constants.
        (human_readable_inexact, human_block_size): Remove.
        (human_readable): Size args are now uintmax_t, not int.
        (human_options): New decl.

        * lib/exclude.c: (new_exclude, add_exclude): Remove casts that are
        unnecessary now that we assume C89 or better.  This change
        imported from coreutils.

        * lib/mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.  This is the same patch as 2003-05-28, but it got lost
        in the 2003-05-30 sync from glibc.

        .h files should stand alone, but we shouldn't include <sys/types.h>
        if we can get away with just <stddef.h>.

        * lib/__fpending.h, addext.c, backupfile.c, exclude.c, getline.c,
        malloc.c, putenv.c, realloc.c, strcasecmp.c: Include <stddef.h>
        rather than <sys/types.h>, as we merely need size_t.
        * lib/dirname.h, memcoll.h, xalloc.h, xmemcoll.h: Include <stddef.h>,
        to get size_t.
        * lib/hash.h, linebuffer.h, readtokens.h, stdio-safer.h, version-etc.h:
        Include <stdio.h>, to get FILE.
        * lib/memcasecmp.c: Don't include <sys/types.h>, as we can assume
        memcasecmp.h has included <stddef.h> and all we need is size_t.
        * lib/memcoll.c: Include "memcoll.h", which gets us size_t and checks
        our interface, instead of including <sys/types.h>

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt ($LIBCSRC/time/mktime.c lib gpl): Comment out for
        now, as glibc mktime is buggy on non-glibc systems.

2003-06-03  Karl Berry  <karl@gnu.org>

        * config/config.sub: update from prep.

2003-06-02  Paul Eggert  <eggert@twinsun.com>

        [from coreutils]
        Fix some minor time-related bugs with POSIX time arguments.
        Some valid time stamps were being rejected (notably -1, and
        time stamps before 1900 on 64-bit hosts).  And some invalid
        time stamps were being accepted, e.g. September 31.

        * lib/posixtm.h (posixtime): Return bool instead of time_t, so
        that we can return (time_t) -1 successfully.
        * lib/posixtm.c: Likewise.
        [HAVE_STDBOOL_H]: Include <stdbool.h>.
        (bool, false, true) [!HAVE_STDBOOL_H]: New type.
        (t): Remove static var.
        (year, posix_time_parse): Now takes struct tm * arg to modify, instead
        of static var.  All uses changed.
        (year): Do not reject years before 1900; they can occur with
        64-bit time_t.
        (posix_time_parse): Do not check for out-of-range components;
        that is now the caller's responsibility, since our checks were
        only approximations.
        (posixtime): Use mktime to check for out-of-range components,
        since it knows them exactly.
        If mktime returns (time_t) -1, check whether an error actually occurred
        by invoking localtime on -1.
        (main) [TEST_POSIXTIME]: Check for input data errors, and report
        posixtime failures better.
        Improve the test data (in comments only).

2003-06-02  Karl Berry  <karl@gnu.org>

        * config/mkinstalldirs (version): new variable.
        (--version): new option.
        (usage): improve message.

        lib/xstrtol.c: Include <limits.h> without checking for HAVE_LIMITS_H.
        * lib/backupfile.c, lib/fsusage.c, lib/hash.c, lib/human.c,
        lib/safe-read.c, lib/userspec.c, lib/xstrtol.c (CHAR_BIT): Don't

        * lib/exclude.c: Include <stdbool.h> unconditionally.
        * lib/tempname.c: Include <stddef.h> unconditionally.
        * lib/hash.c: Include <limits.h>, since we no longer define CHAR_BIT.
        * lib/modechange.c, rpmatch.c (NULL): Don't define, since
        <stddef.h> does that.
        * lib/quote.c: Dont include <stddef.h> or <sys/types.h>; not needed.
        * lib/safe-read.c (INT_MAX): Don't define, since <limits.h> does that.
        * lib/safe-read.c (TYPE_MINIMUM, TYPE_MAXIMUM): Remove; no longer
        needed.
        * lib/xstrtol.c: Likewise.
        * lib/safe-read.c: Remove TYPE_SIGNED; no longer needed.
        * lib/savedir.c: Include <stddef.h> instead of defining NULL.

        * lib/addext.c (addext): Use assignment rather than cast, to avoid
        warnings on some platforms.

        * lib/mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.

2003-05-26  Jim Meyering  <jim@meyering.net>

        Merge in a change from coreutils:
        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Test the cache variable, not one
        that is guaranteed to be `no'.  Use `no_such_member' to indicate
        that condition, rather than `-1' which is slightly misleading.
        Change the name of the cache variable to have the gl_ prefix.
        Prompted by a patch from Richard Dawe for DJGPP.

2003-05-24  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from prep.

2003-05-22  Karl Berry  <karl@gnu.org>

        * gnulib-tool (func_usage): =LIBRARY not =libRARY in help msg.

2003-05-20  Karl Berry  <karl@gnu.org>

        * config/config.guess: update from prep.

2003-05-18  Karl Berry  <karl@gnu.org>

        * config/srclistvars.sh (TEXMF): use TEXMFROOT instead, since TEXMF
        might actually be set by the user.

        * config/depcomp, install-sh, mdate-sh: update from automake.

2003-05-17  Bruno Haible  <bruno@clisp.org>

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Fix a quoting bug leading to an
        invalid expansion for AC_EGREP_CPP.
        * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Likewise.
        * m4/strtoumax.m4 (gl_FUNC_STRTOUMAX): Likewise.
        Suggested by Akim Demaille <akim@epita.fr> in

2003-05-12  Bruno Haible  <bruno@clisp.org>

        * lib/linebreak.c (iconv_string_length): Don't return -1 just because
        the string is longer than 4 KB.

2003-05-11  Karl Berry  <karl@gnu.org>

        2003-01-19  Ulrich Drepper  <drepper@redhat.com>

        From GNU libc.
        * lib/strftime.c (my_strftime): Handle very large width
        specifications for numeric values correctly.  Improve checks for
        overflow.

        2003-01-19  Jim Meyering  <jim@meyering.net>

        * lib/strftime.c (widen) [COMPILE_WIDE]: Merge nearly-identical
        definitions.
        (nl_get_alt_digit) [! defined my_strftime]: Define.
        (my_strftime) [_NL_CURRENT]: Merge nearly-identical uses of
        _nl_get_alt_digit and _nl_get_walt_digit.

        * lib/strftime.c (my_strftime): Merge in locale-related changes from
        libc. These changes have no effect outside of _LIBC.

        Add test-cases for DOS filenames. Declare program_name.
        (main): Set up program_name.  Patch by Rich Dawe.

        * lib/mountlist.c (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

        (EXCLUDE_macros_do_not_collide_with_FNM_macros): Use FNM_PATHNAME
        instead of FNM_FILE_NAME, for compatibility with pure POSIX sytems.

2002-12-06  Paul Eggert  <eggert@twinsun.com>

        Undo the 2001-07-02 change for jm-glibc-io, as it was too much of
        a pain in practice to deal with generated m4 files.  This change
        goes together with the 2002-12-04 unlocked-io.h change in ../lib.

        * m4/Makefile.am.in (Makefile.am): Don't mention jm-glibc-io.m4n
        and jm-glibc-io.m4, as they are no longer a special case.
        * m4/jm-glibc-io.m4: Rename from jm-glibc-io.m4n, and remove the
        kludge and the auto-generation stuff.  Check only whether the
        functions are declared, not whether they exist, since older hosts
        that don't declare the functions can't use the optimization anyway.

2002-12-06  Jim Meyering  <jim@meyering.net>

        * lib/error.c: Be consistent: change `#ifndef _LIBC' to `#if !_LIBC'.

        for the merge of gnulib's changes back into libc.

        * lib/error.c (_): Define only if not already defined.
        Move definition to follow all #include directives.

        Check for arithmetic overflow when computing combined size.

2002-12-04  Paul Eggert  <eggert@twinsun.com>

        maintain it by hand.

        * lib/unlocked-io.h: New file, from GNU diffutils,
        but with proper copyright notice and attribution.
        * lib/gen-uio: Remove.

        * lib/lstat.c: New file. Simply #define LSTAT and include stat.c.

        * lib/safe-read.c: Rework so that it may serve to define safe_write,
        too.
        * lib/safe-write.c: Simply #define SAFE_WRITE and include safe-read.c.

2002-12-03  Jim Meyering  <jim@meyering.net>

        but not semantics, to minimize the differences between these two files.
        (safe_read): Change comment to mention SAFE_READ_ERROR.

        * lib/safe-read.c (IS_EINTR): Define.

        hash_find_entry, hash_rehash): Replace `if (limit <= value) abort ();'
        with `if (! (value < limit)) abort ();', for readability.

2002-11-26  Karl Berry  <karl@gnu.org>

        * lib/strdup.c: copy from libc again, with jim's ok.
        * lib/.cppi-disable: re-add strdup.c

2002-11-25  Karl Berry  <karl@gnu.org>

        * lib/strtoll.c: copy from libc, meaning we now #include <strtol.c>
        instead of "strtol.c".

2002-11-25  Karl Berry  <karl@gnu.org>

        * config/install-sh: update from automake for variable quoting, $0 in

        Based on a report from Greg Schafer.

2002-11-23  Jim Meyering  <jim@meyering.net>

        * lib/fsusage.c: Remove unneeded parentheses around operands of
        `defined'.

        * lib/quotearg.h: Allow multiple inclusion by surrounding with
        "#ifndef QUOTEARG_H_".  Include <stddef.h>, for size_t,
        so that we can be included first.
        (PARAMS): Remove; we now assume C89 or later.  All uses removed.
        * lib/quotearg.c: Include quotearg.h immediately after config.h.
        No need to include stddef.h or sys/types.h any more.
        Surround local include files with "", not "<>".
        Assume HAVE_LIMITS_H unconditionally, as we assume C89.

2002-11-22  Paul Eggert  <eggert@twinsun.com>

        * lib/hash.c: Avoid use of <assert.h>, as the GNU Coding Standards
        hint that one should use `if (! x) abort ();' rather than `assert
        (x);', and anyway it's one less thing to worry about configuring.
        (hash_lookup, hash_get_first, hash_get_next, hash_find_entry,
        hash_rehash, hash_insert): Use abort rather than assert.

        <stdint.h>.
        (UINTMAX_MAX) [!defined UINTMAX_MAX]: New macro.
        (PROPAGATE_ALL_ONES): Work even if X is unsigned and narrower than
        int.  Work more efficiently if X is the same width as uintmax_t.
        Do not compare X to -1, to avoid bogus compiler warning.
        (get_fs_usage): (uintmax_t) -1 -> UINTMAX_MAX to avoid a cast.
        Don't assume that f_frsize and f_bsize are the same type.

        (make_path): Minor reformatting.

        AC_FUNC_MALLOC and AC_FUNC_REALLOC: test #ifndef
        HAVE_MALLOC/HAVE_REALLOC.

        * lib/mountlist.h (ME_DUMMY): Don't count entries of type `auto' as
        dummy ones.  At least on GNU/Linux systems, `auto' means something
        else.
        From Michael Stone.

2002-11-21  Bruno Haible  <bruno@clisp.org>

        * lib/argmatch.c: Include config.h here, not in argmatch.h.
        Include stdlib.h, for EXIT_FAILURE.
        Always include <string.h>, since we assume C89.
        (EXIT_FAILURE): Remove pre-C89 bug workaround.
        * lib/argmatch.h: Do not include <config.h> or <sys/types.h>.
        Include <stddef.h> instead, since it's all we need for size_t.
        (PARAMS): Remove.  All uses removed.
        (ARRAY_CARDINALITY): Do not bother to #undef.

        * config/srclist.txt: can't copy install-sh/mkinstalldirs from
        installed automake until the next release, since changes have been
        made.

2002-09-25  Karl Berry  <karl@gnu.org>

2002-06-26  Paul Eggert  <eggert@twinsun.com>

        * lib/fnmatch.c, fnmatch_loop.c (WIDE_CHAR_SUPPORT):
        New macro.  Use it uniformly instead of
        (defined HAVE_WCTYPE_H && defined HAVE_WCHAR_H).
        It also uses HAVE_BTOWC, to fix a porting bug on Solaris 2.5.1
        reported by Vin Shelton.

2002-06-22  Paul Eggert  <eggert@twinsun.com>

        * lib/c-stack.h (segv_handler, c_stack_action) [! defined SA_SIGINFO]:

        * m4/prereq.m4 (jm_PREREQ_EXCLUDE): Likewise, wrt jm_FUNC_FNMATCH.

        Update to latest tools.  Suggestions from Paul Eggert.
        * m4/stdbool.m4: New file, from diffutils-2.8.2.
        * m4/gnu-source.m4: Update from diffutils-2.8.2.

        to AC_HEADER_STDBOOL

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * lib/fnmatch.c (ISASCII, ISPRINT): Undefine, to avoid warning about
        redefinition due to Solaris 2.6's definition in /usr/include/sys/euc.h.

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * lib/c-stack.c, lib/c-stack.h: New files, from diffutils-2.8.2.

        From Alfred M. Szmidt.

2002-06-18  Paul Eggert  <eggert@twinsun.com>

        * lib/file-type.h: Report an error if neither S_ISREG nor
        S_IFREG is defined, instead of using a test specific to glibc
        2.2.  This should be safe, since POSIX requires S_ISREG and
        Unix Version 7 had S_IFREG.  We don't need to check for
        <sys/types.h> since we don't use any symbols that it defines.

2002-06-15  Richard Dawe  <richdawe@bigfoot.com>

        * lib/Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than
        $@-t, so that each temporary file name is unique and valid in the first
        8 characters, for operation under DOS.

2002-06-15  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Check for st_author.

        Work even with DJGPP 2.03, which lacks support for symlinks.
        From Richard Dawe.
        * lib/xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK
        is defined.
        * lib/lchown.c (S_ISLNK): Likewise.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        * lib/file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef.
        For GNU libc 2.2 and newer, ensure that <sys/types.h> and <sys/stat.h>
        have been included before this file.

2002-06-14  Jim Meyering  <meyering@lucent.com>

        * lib/file-type.h: Use the version from diffutils-2.8.2.
        * lib/file-type.c: Likewise.

        * m4/prereq.m4 (jm_PREREQ_STAT): Check for sys/param.h and sys/mount.h.
        They're needed at least for NetBSD 1.5.2.
        ($statxfs_includes): Include those same headers.
        ($statxfs_includes): Include sys/vfs.h if available.
        ($statxfs_includes): Likewise for sys/statvfs.h.
        Check for the following members in both structs statfs and statvfs:
        f_basetype, f_type, f_fsid.__val, f_namemax, f_namelen.

2002-06-01  Jim Meyering  <meyering@lucent.com>

        * m4/d-type.m4 (jm_CHECK_TYPE_STRUCT_DIRENT_D_TYPE): Rename macro:
        s/D_TYPE_IN_DIRENT/HAVE_STRUCT_DIRENT_D_TYPE/.

2002-05-28  Jim Meyering  <meyering@lucent.com>

        * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `mkdir', not `rmdir'.
        Reported by Volker Borchert.

2002-05-27  Jim Meyering  <meyering@lucent.com>

        Fix a problem seen only on nonconforming systems whereby ls.c's
        use of localtime, and then of gettimeofday would cause trouble:
        the localtime call used to initialize rpl_gettimeofday's save
        mechanism would clobber ls's current local time information so
        that in any long listing the first file would always be listed
        with date 1970-01-01.  Analysis by Volker Borchert.

        * lib/gettimeofday.c (localtime): Undefine.
        (rpl_localtime): New function.

2002-05-27  Jim Meyering  <meyering@lucent.com>

        * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Also replace
        localtime.

        * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `rmdir' so we don't try to
        use the replacement function; it wouldn't resolve at link time.
        Reported by Volker Borchert.

2002-05-22  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Add file-type.c and
        file-type.h.
        * lib/file-type.h: New file.
        * lib/file-type.c (file_type): New file/function.  Extracted from
        diffutils.

2002-04-30  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_STAT.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_SIG2STR): Remove; all callers changed.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): Check for stdlib.h.
        Do not check for alloca.h (no longer used) or stdbool.h (was never
        used?).  Add AM_C_PROTOTYPES since hard-locale.h uses it.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * lib/hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.

2002-04-29  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_MACROS): Remove use of AC_FUNC_STRNLEN.
        * m4/prereq.m4: Add jm_PREREQ_STRNLEN.
        Use AC_FUNC_STRNLEN here instead.

        * m4/jm-macros.m4: Don't AC_REQUIRE([AC_PROG_CC_STDC]).
        With autoconf-2.53a, it's part of AC_PROG_CC.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Add AC_REPLACE_FUNCS(sig2str).
        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_SIG2STR.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * lib/sig2str.h, lib/sig2str.c: New files.
        * lib/Makefile.am (libfetish_a_SOURCES): Add sig2str.h.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * lib/sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid
        depending on <sys/wait.h> and WTERMSIG.  Default to 64 instead
        of 127, since 64 is the largest conceivable number for ancient
        nonstandard hosts.
        * lib/sig2str.c: Do not include <sys/wait.h>; no longer needed.

2002-04-28  Jim Meyering  <meyering@lucent.com>

        * lib/sig2str.c (WTERMSIG): Remove definition (unused).

2002-04-24  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): New macro.
        (jm_PREREQ): Use it.

        * m4/getloadavg.m4: Check for these headers: locale.h unistd.h
        mach/mach.h fcntl.h.
        Check for this function: setlocale.

2002-04-24  Jim Meyering  <meyering@lucent.com>

        * lib/gettext.h: New file, from Gettext.
        * lib/Makefile.am (INCLUDES): Remove -I../intl.
        (libfetish_a_SOURCES): Add gettext.h.

2002-04-16  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Also check for these members:
        ut_pid, ut_id, ut_exit.

2002-04-16  Jim Meyering  <meyering@lucent.com>

        (HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_TYPE): Define.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (checking for getmntinfo function...): Remove
        now-bogus check for f_type in sys/mount.h.  Instead, just test for the
        existence of the getmntinfo function.  Needed for Darwin 5.3.

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Also detect when dirfd is a macro.
        This is necessary at least on Darwin 5.3.

        * m4/jm-macros.m4: Don't AC_REPLACE(strnlen), now that we use
        AC_FUNC_STRNLEN.  Otherwise, we'd end up putting two copies of
        strnlen.o in the library, and that makes some versions of ranlib
        object.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * lib/dirfd.h (dirfd): Elide prototype if dirfd is a macro.

2002-04-09  Jim Meyering  <meyering@lucent.com>

        * m4/malloc.m4: (jm_FUNC_MALLOC): Change the `checking ...' message
        to be more precise.  Rather than saying we're checking whether the
        function `works', say what we're testing.
        * m4/realloc.m4 (jm_FUNC_REALLOC): Likewise.
        Reported by Bruno Haible.

2002-03-10  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.c (make_path): Remove a comma from a diagnostic.
        Suggestion from Santiago Vila.

        * lib/rename.c: Mention that this wrapper is needed also on
        mips-dec-ultrix4.4 systems.

2002-03-02  Jim Meyering  <meyering@lucent.com>

        * lib/gettime.c (gettime): Test HAVE_CLOCK_GETTIME,

        * m4/jm-macros.m4 (jm_MACROS): Require AC_FUNC_ACL.
        Do not check for acl or sys/acl.h, as AC_FUNC_ACL does that now.

2002-02-25  Paul Eggert  <eggert@twinsun.com>

        * lib/acl.c, lib/acl.h: New files.
        * lib/Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c.

2002-02-24  Jim Meyering  <meyering@lucent.com>

        * lib/strnlen.c (strnlen): Define-away/undef so that an inconsistent
        prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't
        cause trouble.  Reported by Nelson Beebe.

2002-02-23  Paul Eggert  <eggert@twinsun.com>

        * lib/path-concat.c (xpath_concat): Reorder code to pacify
        compilers that don't know that xalloc_die never returns.

2002-02-20  Jim Meyering  <meyering@lucent.com>

        * lib/getdate.c: Regenerate using bison-1.33.

2002-02-17  Jim Meyering  <meyering@lucent.com>

        * config/config.guess (main): Don't use `head -1'; it's no longer
        portable. Use `sed 1q' instead.

2002-02-16  gettextize  <bug-gnu-gettext@gnu.org>

2001-12-15  Jim Meyering  <meyering@lucent.com>

        * lib/regex.h (__restrict_arr): Update from libc.

        * lib/mountlist.h (ME_REMOTE): Recognize file systems of type smbfs

        * lib/modechange.c (mode_compile): Add cast to avoid pedantic warning
        about `signed and unsigned type in conditional expression'.
        * lib/posixtm.c (posix_time_parse): Likewise.

        * lib/xreadlink.c (xreadlink): Add cast to avoid a pedantic warning.

2001-12-02  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c: Don't declare getenv, thus reverting the change of
        2001-11-18.  It's no longer necessary, now that stdlib.h is always
        included.

        * lib/regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * lib/xstrdup.c: Include xalloc.h, so that xstrdup is declared

        Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c: Merge with version from libc.
        * lib/regex.c: Likewise.

        * lib/tempname.c: Include stdlib.h unconditionally.  On some old
        systems for which STDC_HEADERS is 0, it was not included, resulting in
        a warning about an integer-to-pointer conversion problem with getenv.
        Reported by Volker Borchert.

2001-11-26  Jim Meyering  <meyering@lucent.com>

2001-11-20  Jim Meyering  <meyering@lucent.com>

        * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Update comment to reflect that
        SunOS 4.1.4 and Solaris 2.5.1 lose, too.

2001-11-19  Jim Meyering  <meyering@lucent.com>

        * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Don't bother with a temporary

        Suggestion from Paul Eggert.

        * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Close each descriptor
        immediately, so the test doesn't mistakenly hit the max-open-files

        * lib/tempname.c (TMP_MAX): Remove; no longer needed.
        (TEMPORARIES): New macro.
        (__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
        removes an artificial limitation (e.g. HP-UX 10.20, where
        TMP_MAX is 17576).

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_TEMPNAME): Check for declaration of getenv.

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * lib/tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
        on SunOS 4.

        * lib/Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
        files will be created before anything else.

2001-11-17  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-winsz1.m4 (jm_WINSIZE_IN_PTEM): Do not define
        WINSIZE_IN_PTEM if <termios.h> defines struct winsize.

2001-11-17  Jim Meyering  <meyering@lucent.com>

        Prompted by a report from Bob Proulx.

        * m4/jm-macros.m4 (jm_MACROS): Don't test for mkstemp here.

        * m4/jm-macros.m4 (jm_MACROS): Remove code to set POW_LIBM.
        Now, that's done as part of AC_FUNC_STRTOD.

2001-11-17  Jim Meyering  <meyering@lucent.com>

        * lib/modechange.c (mode_adjust): Fix error introduced on 1999-04-26
        that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
        rather than group writable.  Patch by Juan F. Codagnone.

        * lib/readtokens.c: Remove explicit declarations of xmalloc and
        xrealloc, Instead, include "xalloc.h".

        * lib/mountlist.c: Include unlocked-io.h after all system headers.
        Remove explicit declarations of xmalloc, xrealloc,
        and xstrdup.  Instead, include "xalloc.h".

        * lib/argmatch.c, closeout.c, error.c, exclude.c: Include
        unlocked-io.h.
        * lib/fatal.c, getdate.y, getpass.c, getstr.c, getusershell.c:
        Likewise.
        * lib/mountlist.c, posixtm.c, readtokens.c, readutmp.c: Likewise.

        * lib/regex.c, sha.c, version-etc.c, yesno.c: Likewise.
        Reported by Padraig Brady.

        * lib/mkstemp.c: #undef mkstemp.
        Include config.h.
        (rpl_mkstemp): Rename from mkstemp.
        Protoize.

2001-11-16  Jim Meyering  <meyering@lucent.com>

        * lib/physmem.c [HAVE_SYS_PSTAT_H]: Include <sys/pstat.h>.
        (physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to
        determine the amount of total physical memory, use pstat_getstatic.
        HPUX-11 doesn't define _SC_PHYS_PAGES.
        (physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]:
        If sysconf couldn't be used to determine the amount of available
        physical memory, use both pstat_getstatic and pstat_getdynamic.
        Based on a patch from Bob Proulx.

2001-11-10  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_PHYSMEM): New function.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * m4/jm-glibc-io.m4n (jm_FUNC_GLIBC_UNLOCKED_IO): Quote first arg
        of AC_DEFUN.

        * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Rework so dirfd.c doesn't have to
        know the name of the variable in the macro definition.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * lib/argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args
        in argmatch_to_argument call.

        * lib/dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an
        argument.

        * lib/hash.c (hash_clear): Fix a bug that could lead to an infloop or
        e.g., a fault due to an attempt to free a NULL pointer.

2001-10-21  Paul Eggert  <eggert@twinsun.com>

        * lib/regex.c (uintptr_t): Remove macro and decl; it's config.h's job.

2001-10-21  Jim Meyering  <meyering@lucent.com>

        * lib/obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,
        this code would end up calling gettext even in packages built
        with --disable-nls.
        * lib/getopt.c (_): Likewise.
        * lib/regex.c (_): Likewise.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * m4/error.m4 (jm_PREREQ_ERROR):
        Do not invoke AC_CHECK_FUNCS with strerror_r, as
        AC_FUNC_STRERROR_R does that.
        Check for strerror declaration.

        * m4/strerror_r.m4: Add copyright notice, as nontrivial m4 files
        are supposed to have them these days.
        (AC_FUNC_STRERROR_R): Always do char* test, so that it gets cached.
        Merge changes from latest Autoconf CVS.
        Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
        and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
        POSIX decided to standardize on the int flavor of strerror_r.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * lib/error.c (strerror_r): Do not declare unless !_LIBC.
        Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P.

        (private_strerror): Use prototypes, not old-style function definition.
        (print_errno_message): New function.
        Support the POSIX 'int'-flavored strerror_r, as well as the traditional
        char*-flavored one.
        (error_tail, error, error_at_line): Use it.

2001-10-11  Jim Meyering  <meyering@lucent.com>

        * lib/argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...
        and quote_n (1, ... to avoid clobbering a buffer.

2001-10-05  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and
        hash-pjw.h.
        * lib/hash-pjw.c: New file (factored out of fileutils' remove.c).
        * lib/hash-pjw.h: New file.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): See if
        `struct fsstat' has the `f_fstypename' member.
        Use that to define FS_TYPE, which is now used to make
        the getfsstat link test tighter.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * lib/mountlist.c [MOUNTED_GETFSSTAT]:

        (read_filesystem_list): Use FS_TYPE.

2001-09-29  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (excluded_filename): 0 -> false, since it's
        a boolean context.

2001-09-29  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
        [one-argument getmntent function]): Include stdio.h before mntent.h.
        SunOS 4.1.x needs it for the declaration of `FILE'.
        Patch by Volker Borchert.

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS)
        Check for these headers: sys/param.h sys/ucred.h sys/mount.h
        sys/fs_types.h, and make the link-test for getfsstat guard #include
        directives with appropriate #if HAVE_*_H tests so that we can
        detect getfsstat on Apple Darwin1.3.7 systems.
        Reported by Nelson Beebe.
        Fix harmless typo in cache variable name: s/getsstat/getfsstat/.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
        #defines strtoimax.  Also treat the other strto* functions
        like strtoimax.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
        Check for strtoul and strtoumax,
        as those declarations are made even in the signed case.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX):
        Likewise, for strtol and strtoimax.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which

        like strtoimax.

        * lib/xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL.
        (strtoul): Do not declare if HAVE_DECL_STRTOUL.
        (strtoimax, strtoumax): Do not declare if already defined as a macro.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        Most macros in unlocked-io.h had the wrong number of arguments.
        * lib/gen-uio: New script.
        (USE_UNLOCKED_IO): Define to 1 if not already defined.
        * lib/unlocked-io.hin: Remove file.
        * lib/Makefile.am (unlocked-io.h): Rewrite to use a separate script,
        rather than trying to embed it here.
        (EXTRA_DIST): Add gen-uio.  Remove unlocked-io.hin
        Reported by Padraig Brady.

2001-09-25  Volker Borchert  <bt@teknon.de>

        `result'.

2001-09-24  Jim Meyering  <meyering@lucent.com>

        * m4/gettext.m4: Use the version from gettext-0.10.40, not CVS.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Add a compile-test
        instead of the mere test for existence of mntent.h.  The latter
        would get a false-positive on AIX 3.4 systems.
        In the outer getmntent if-block, don't die if neither of the getmntent
        tests succeeds.  Instead, just fall through and continue with the
        remaining tests.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * lib/mountlist.c: Remove useless parentheses in #if directives.

        * m4/isc-posix.m4: Decrement serial number to sync with gettext.
        * m4/glibc21.m4: Likewise.

2001-09-22  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c: Update from latest gettext.
        * lib/config.charset: Likewise.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Check for declaration of
        strtoimax.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Check for declaration of
        strtoumax.

2001-09-20  Jim Meyering  <meyering@lucent.com>

        * lib/xstrtol.c (strtoimax): Guard declaration with
        `#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
        The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
        have their own, conflicting declaration of strtoimax in sys/inttypes.h.
        (strtoumax): Likewise, for completeness (it wasn't necessary).

2001-09-17  Paul Eggert  <eggert@twinsun.com>

        * lib/strtoimax.c (HAVE_LONG_LONG):
        Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.
        (strtoimax): Use sizeof (long), not sizeof strtol (ptr, endptr, base),
        to work around bug in IBM C compiler.

        whenever the right hand side need not be expanded by the shell.

2001-09-16  Paul Eggert  <eggert@twinsun.com>

        * m4/fnmatch.m4 (jm_FUNC_FNMATCH): Remove test for GNU C
        library.  It's not correct, as some older glibcs are buggy.
        fnmatch wasn't fixed until glibc 2.2.

        Use AC_DEFINE, not AC_DEFINE_UNQUOTED, as there's no
        special shell magic here.

2001-09-16  Jim Meyering  <meyering@lucent.com>

        * m4/mkdir-slash.m4 (UTILS_FUNC_MKDIR_TRAILING_SLASH): New file/macro.

        The body, by Paul Eggert, was moved here from configure.in.
        * m4/jm-macros.m4: Require UTILS_HOST_OS.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_XREADLINK): New macro.
        (jm_PREREQ): Use it.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * lib/xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
        Use ssize_t, not int, to store result of readlink.
        Check for ssize_t overflow as well as size_t overflow,
        as POSIX says the result of readlink is implementation-defined
        when ssize_t overflows.
        Remove unnecessary cast to char*.
        Use free+malloc instead of realloc, as the storage doesn't need
        to be preserved and it's clearer and can be more efficient that way.
        (SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
        * lib/xreadlink.h (xreadlink): Update prototype.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Revert some of the previous change; intead,
        fix the HAVE_GETCWD_NULL code to behave more like the
        !HAVE_GETCWD_NULL code used to.

        Include "xalloc.h".
        (xgetcwd): Do not return NULL when memory is exhausted; instead,
        invoke xalloc_die.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ_XGETCWD): Check for limits.h and
        sys/param.h, as pathmax.h includes them.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_XGETCWD.
        (jm_PREREQ_XGETCWD): New macro.

        * m4/getcwd.m4: New file.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
        like the HAVE_GETCWD_NULL code.
        Include pathmax.h if not HAVE_GETCWD.
        Do not include xalloc.h.
        (INITIAL_BUFFER_SIZE): New symbol.
        Do not use xmalloc / xrealloc, since the caller is responsible for
        handling errors.  Preserve errno around `free' during failure.
        Do not overrun buffer when using getwd.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
        __GLIBC__ && __GLIBC__ >= 2), to decide whether to use
        getcwd (NULL, 0).

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (fnmatch_no_wildcards): Fix confusion between
        usage of FNM_CASEFOLD and FNM_LEADING_DIR.  The bug was
        spotted by Jim Meyering.

2001-09-03  Jim Meyering  <meyering@lucent.com>

        * lib/xreadlink.c (xreadlink): Preserve errno around `free' during
        failure.

2001-09-02  Jim Meyering  <meyering@lucent.com>

        * lib/error.c: Update from GNU libc.

        * lib/xreadlink.c: New file.
        * lib/xreadlink.h: New file.
        * lib/Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and
        xreadlink.h.

        * lib/regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
        doesn't conflict with sparc Solaris 7's definition in
        /usr/include/sys/int_types.h.

        * lib/exclude.c: Use `""', not `<>' to #include non-system header
        files.
        (fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
        and strncasecmp as r-values.  Unixware didn't have declarations.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.h: Add copyright notice.
        (_DECLARE_XSTRTOL): Improve quality of diagnostic for
        LONGINT_INVALID_SUFFIX_CHAR.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xstrtol.c (strtoimax): New decl.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/xgetcwd.c: Don't include pathmax.h.
        Include stdlib.h and unistd.h if available.
        Include xalloc.h.
        (xmalloc, xstrdup, free): Remove decls.
        (xgetcwd): Don't assume sizes fit in unsigned.
        Check for overflow when computing sizes.
        Simplify reallocation code.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/savedir.c (savedir): Remove size parameter, as POSIX says that
        a directory's st_size can have an arbitrary value, so the old
        usage could waste an arbitrary amount of memory.  All uses
        changed.
        * lib/savedir.h: Update prototype.

2001-08-31  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.

        * lib/strtoimax.c: Renamed from strtoxmax.c, removing the
        old strtoimax.c.

        Also, make the following further changes to make this file's
        configuration more similar to that of strtol.c:
        (UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
        (strtoumax, uintmax_t, strtoull, strtol): Remove.
        (intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
        (strtoimax): Renamed from strtoumax.  All uses of unsigned values
        changed to signed values.

        And make the following changes as well:
        Fix copyright notice, as 1999 was missing.
        (verify): New macro.
        (strtoimax): Check sizes at compile-time, not run-time.
        Prefer strtol to strtoll if both work.
        (main): Remove; it was not that useful and was a pain to maintain.

        * lib/strtoumax.c: Include strtoimax.c, not strtouxmax.c.

2001-08-31  Jim Meyering  <meyering@lucent.com>

        * lib/xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
        Use an initial, malloc'd, buffer of length 128 rather than
        a statically allocated one of length 1024.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Simplify code, partly by assuming autoconf 2.52 semantics.

        * m4/Makefile.am (EXTRA_DIST): Remove uintmax_t.m4.

        * m4/inttypes.m4 (AC_PREREQ): Bump to 2.52.
        (jm_AC_HEADER_INTTYPES_H): Remove; now done by autoconf in 2.52.
        All uses removed.
        (jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T):
        Move AC_REQUIRE to next-to-top level, to avoid confusion.
        Use 2.52's AC_CHECK_TYPE instead of merely looking for the header.
        * m4/prereq.m4 (jm_PREREQ_HUMAN): Don't require
        jm_AC_HEADER_INTTYPES_H.
        * m4/jm-macros.m4 (jm_MACROS): Likewise.

        * m4/uintmax_t.m4: Remove, as it duplicates inttypes.m4.

        * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX):
        Quote first arg of AC_DEFUN.
        Require jm_AC_TYPE_UINTMAX_T and jm_AC_TYPE_UNSIGNED_LONG_LONG
        since they are needed to parse the include file even if we need
        only xstrtoimax.  Simplify logic behind the args to AC_REPLACE.
        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Likewise,
        but with opposite signedness.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Merge 'exclude' changes from tar 1.13.22.
        This fixes one or two unlikely storage allocation overflow bugs,
        but doesn't change user-visible behavior otherwise.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_EXCLUDE.
        (jm_PREREQ_EXCLUDE): New macro.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
        tm to be declared.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/hash.c: Remove '2001' from copyright notice.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/full-write.h: New file.
        * lib/Makefile.am (libfetish_a_SOURCES): Add full-write.h.
        * lib/full-write.c: Correct credits, as cccp.c no longer
        exists and anyway it was so heavily changed from the old cccp
        code as to be unrecognizable.  Include full-write.h.
        (full_write): Return size_t, with short writes meaning failure.
        All callers changed.  This fixes a bug with large buffers
        on 64-bit hosts.
        * lib/utime.c: Include full-write.h.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/exclude.c (bool): Declare, perhaps by including stdbool.h.
        (<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
        (<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
        Include if available.
        (<xalloc.h>): Include
        (SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
        (verify): New macro.  Use it to verify that EXCLUDE macros do not
        collide with FNM macros.
        (struct patopts): New struct.
        (struct exclude): Use it, as exclude patterns now come with options.
        (new_exclude): Support above changes.
        (new_exclude, add_exclude_file):
        Initial size must now be a power of two to simplify overflow checking.
        (free_exclude, fnmatch_no_wildcards): New function.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.
        (excluded_filename, add_exclude):
        Add support for the fancy new exclusion options.
        (add_exclude, add_exclude_file): Now takes int options arg.
        Check for arithmetic overflow when computing sizes.
        (add_exclude_file): xrealloc might modify errno, so don't
        realloc until after errno might be used.

        * lib/exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS):
        New macros.
        (free_exclude): New decl.
        (add_exclude, add_exclude_file): Now takes int options arg.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * lib/alloca.c (alloca): Arg is of type size_t, not unsigned.

2001-08-27  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c

        * lib/version-etc.c (N_): Remove definition.
        Revert most of last change.
        Instead, simply don't mark the `Copyright...' string for translation.
        Based on advice from Paul Eggert.

        * lib/strtoxmax.c: Tweak comment.

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Require jm_AC_PREREQ_XSTRTOIMAX.

        * m4/xstrtoimax.m4: New file.
        * m4/xstrtoumax.m4: Add comments explaining why we
        AC_REPLACE_FUNCS(strtol).

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * lib/version-etc.c (version_etc_copyright_fmt): Replace literal year
        of copyright with `%s' so translators don't get an untranslated
        message in 2002.
        (COPYRIGHT_YEAR): Define.
        (version_etc): Use fprintf rather than fputs.
        Suggestion from Ulrich Drepper.

        * lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.

        * lib/strtoll.c: New file, from GNU libc.
        * lib/xstrtoimax.c: New file.

        * lib/xstrtol.h: Add xstrtoimax.
        * lib/strtoumax.c: New file.  Simply include "strtoumax.c".
        * lib/strtoimax.c: New file.  Likewise, but first define
        STRTOUXMAX_SIGNED.

        * lib/strtoumax.c: Factor to work both for unsigned and signed types,
        ...
        * lib/strtoxmax.c: ... then renamed to this.

2001-08-18  Paul Eggert  <eggert@twinsun.com>

        * m4/inttypes.m4: Add AC_PREREQ(2.13).
        (jm_AC_HEADER_INTTYPES_H): Test for intmax_t, too.
        (jm_AC_TYPE_INTMAX_T): New macro.
        (jm_AC_TYPE_UINTMAX_T): Moved here from uintmax_t.m4.

        * m4/uintmax_t.m4: Removed.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (unlocked-io.h): Do not append "_unlocked" twice.
        Port to Solaris 8, where 'sed' requires a space after the 'r'
        command, and where sh dislikes "$/".  Clean up the spacing a bit.
        Redirect output to $tmp just once.

2001-08-12  Paul Eggert  <eggert@sic.twinsun.com>

        * lib/addext.c (<errno.h>): Include.
        (errno): Declare if not defined.
        (addext): Work correctly when pathconf returns -1 and leaves
        errno alone because there is no limit.  Also, work even if
        pathconf returns a value greater than SIZE_MAX.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        Simply `return getcwd (NULL, 0);'.
        [! (defined __GLIBC__ && __GLIBC__ >= 2)]:
        Use 1300 as initial value for length, not PATH_MAX.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible.

        * lib/mbswidth.h (MBSW_REJECT_UNPRINTABLE, MBSW_REJECT_INVALID):
        Renamed from MBSW_ACCEPT_UNPRINTABLE and MBSW_ACCEPT_INVALID
        with inverted sense.  All uses changed.

        * lib/mbswidth.c: Don't include <limits.h>.
        Include <stdlib.h> and <string.h> unconditionally.
        (iswcntrl, mbsinit, ISCNTRL): New macros.
        (mbsnwidth): Use K&R style function declarations.
        Don't bother checking for MB_LEN_MAX == 1, since the compiler
        can optimize it when MB_CUR_MAX == 1.
        The width of control characters is zero, not 1.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible, except that getline.m4 continues to use AC_LIBOBJ.

        * m4/codeset.m4: Upgrade to serial AM1.

        2001-06-25  Bruno Haible  <haible@clisp.cons.org>
        * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Don't require AM_C_PROTOTYPES.
        Also check for mbsinit.  Needed for SCO 3.2v5.0.2.
        Also include <string.h>; this is where AIX 3.2.5 declares wcwidth.
        Also check for iswcntrl, used for wcwidth fallback.
        Use AC_TRY_COMPILE to emulate AC_CHECK_DECLS, for portability
        to Autoconf 2.13.

2001-08-03  Jim Meyering  <meyering@lucent.com>

        * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Use `#include', not `@%:@include',

        (libfetish_a_SOURCES): Put all .h files here instead.
        Remove a thus-exposed (better checks in automake) duplicate and
        two unnecessary .h files.

2001-07-04  Jim Meyering  <meyering@lucent.com>

        * m4/Makefile.am.in (glibc-io.struct): New target.  Rework the code
        that generates jm-glibc-io.m4 so that it doesn't trigger any make
        distcheck failure.

2001-07-02  Jim Meyering  <meyering@lucent.com>

        The following changes were prompted by suggestions from Bruno Haible.

        * m4/jm-glibc-io.m4n: New file, the template from which jm-glibc-io.m4
        is now generated.
        * m4/Makefile.am.in (Makefile.am): Include jm-glibc-io.m4n in emitted
        definition of EXTRA_DIST.
        (Makefile.am): Emit the dependency, `all-local: jm-glibc-io.m4' to
        ensure that the generated file is created/updated whenever the list
        of $(unlocked_functions) is changed.
        (jm-glibc-io.m4): New rule.
        (unlocked-io.h): New rule -- currently unused.

2001-06-24  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Use a quadrigraph to represent an
        unmatched right bracket, rather than kludging it with an extra,
        falsely-matching quote in a comment.  Patch by Akim Demaille.

2001-06-11  Jim Meyering  <meyering@lucent.com>

        * lib/regex.c: Update from GNU libc.

2001-05-27  Jim Meyering  <meyering@lucent.com>

        quote function.  Reported by Göran Uddeborg.

2001-05-22  Jim Meyering  <meyering@lucent.com>

        * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Don't use AC_LIBOBJ(strftime),
        now that we use the package-supplied version unconditionally.
        (jm_FUNC_STRFTIME): Don't replace strftime, for the same reason.

2001-05-21  Jim Meyering  <meyering@lucent.com>

        * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME):
        Don't bother to check library strftime, since
        we'll be using our own my_strftime function anyway.
        Define my_strftime instead of strftime.

2001-05-20  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * lib/dirname.c (dir_name): Compute append_dot using path, not newpath
        which is not yet declared.

2001-05-15  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4: Use proper quoting so brackets appear in the test
        program.
        Reported by, and with help from, Bruno Haible.

2001-05-13  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (major_t, minor_t): Define to unsigned int if
        undefined.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        dirname code cleanup.  base_name now behaves more compatibly
        with POSIX basename when given file names that have trailing
        slashes, and similarly for dir_name.  Add new primitives
        base_len and dir_len.  Put the directory-name-related decls
        into dirname.h.

        * lib/addext.c (ISSLASH, base_name): Remove; now in dirname.h.
        * lib/backupfile.c (base_name): Likewise.
        * lib/basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
        * lib/dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
        * lib/makepath.c (strip_trailing_slashes): Likewise.
        * lib/path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN,
        ISSLASH): Likewise.
        * lib/rename.c (strip_trailing_slashes): Likewise.
        * lib/same.c (base_name): Likewise.
        * lib/stripslash.c (ISSLASH): Likewise.

        * lib/addext.c: Include <dirname.h> after size_t is defined.
        * lib/backupfile.c: Likewise.

        * lib/addext.c (addext): Use base_len to trim redundant
        trailing slashes instead of doing it ourselves.
        But do not trim the last slash if it is not redundant.

        * lib/backupfile.c (find_backup_file_name,
        max_backup_version): Use base_len instead of rolling it ourselves.
        Handle the case of "" and (on DOS) "C:" correctly.

        * lib/basename.c: Do not include <stdio.h>, <assert.h>; no longer
        needed. Include <string.h>, <dirname.h>.
        (base_name): Allow file names ending in slashes, other than names
        that are all slashes.  In this case, return the basename followed
        by the slashes.  This is more general, and can be used in places
        where the original base_name purposely had an assertion failure.
        (base_len): New function.

        * lib/dirname.c: Include <string.h> instead of <stdlib.h>.
        Do not include <assert.h>; no longer needed.
        Include xalloc.h.
        (memrchr): Remove decl.
        (dir_name_r): Remove.
        (dir_len): Renamed from dirlen.  All callers changed.
        Rewrite in terms of base_name, for simplicity and consistency.
        (dir_name): Never return NULL.  All callers changed.
        Do not include <stdlib.h> in test program; no longer needed.
        return 0; is fine for test program.

        * lib/dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN):
        New macros.
        (base_name, base_len, dir_len, strip_trailing_slashes): New decls.

        * lib/path-concat.c (path_concat): Use base_len to compute
        base length, not strlen; this means we cannot rely on memcpy
        to null-terminate.

        * lib/same.c (STREQ): Remove.
        (same_name): Handle the case where the basename ends in trailing '/'.

        * lib/stripslash.c (strip_trailing_slashes): Return nonzero if
        a slash was stripped.  Do not strip the last slash after a
        file system prefix.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        * lib/Makefile.am (libfetish_a_SOURCES):
        Add strftime.c, since we now compile it on all hosts.

        * lib/strftime.c (my_strftime):
        Define to nstrftime if emacs, but only if my_strftime is not defined.
        (extra_args, extra_args_spec, extra_args_spec_iso): Rename from
        ut_argument, ut_argument_spec, ut_argument_spec_iso, respectively.
        Add one more extra argument: a nanoseconds value.
        All uses changed.
        (ns): New macro.
        (my_strftime function): Add %N format.
        (emacs_strftimeu): Renamed from emacs_strftime,
        with extra ut argument.

2001-05-09  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Do not check for fseeko; no longer used.

2001-04-21  Jim Meyering  <meyering@lucent.com>

        * m4/rmdir-errno.m4: Write to a new file, so that a restrictive umask
        doesn't interfere.

2001-04-21  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/ftruncate.m4: Check for chsize.
        Link with ftruncate.o unconditionally if ftruncate is missing.
        This was required when cross-compiling to i586-mingw32msvc.

2001-04-08  Jim Meyering  <meyering@lucent.com>

        * lib/getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
        recomputed; that's necessary when the offset spans a DST transition.
        Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.

2001-04-02  Jim Meyering  <meyering@lucent.com>

        * lib/regex.h, regex.c: Update from GNU libc.

2001-03-17  Jim Meyering  <meyering@lucent.com>

        * m4/memcmp.m4 (jm_AC_FUNC_MEMCMP): Remove my copy of AC_FUNC_MEMCMP,
        now that the version in autoconf is equivalent.
        (jm_FUNC_MEMCMP): Adjust to use AC_FUNC_MEMCMP.

        * m4/error.m4 (jm_PREREQ_ERROR): Invoke AC_FUNC_STRERROR_R.
        Suggestion from Akim Demaille.

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_TEMPNAME.

        * lib/tempname.c (uint64_t): Define to uintmax_t if
        not defined, and if UINT64_MAX is not defined.
        Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
        Reported by John David Anglin.

2001-03-15  Bruno Haible  <haible@clisp.cons.org>

        * lib/localcharset.c (locale_charset): Allow wildcard syntax. Also
        resolve alias if codeset is empty.
        * lib/config.charset (BeOS): Use wildcard syntax.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * lib/path-concat.c (path_concat)
        [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't insert a backslash when
        concatenating e.g., `C:' and `foo'.
        From Bruno Haible.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        * lib/localcharset.c (locale_charset): Don't use
        setlocale(LC_CTYPE,NULL). Don't return NULL.
        * lib/unicodeio.c (print_unicode_char): Simplify accordingly.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        support for DOS/DJGPP.

2001-03-01  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_MACROS): Use mkstemp replacement if the system
        lacks mkstemp.  Compile our own tempname.c if we compile our own
        mkstemp.c, as mkstemp relies on tempname.

2001-03-01  Jim Meyering  <meyering@lucent.com>

        * m4/dos.m4 (jm_AC_DOS): Remove extra backslashes, now that
        AH_VERBATIM really does output its argument verbatim.

2001-02-28  Paul Eggert  <eggert@twinsun.com>

        * lib/unistd-safer.h: New files.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        The mkstemp replacement is taken from glibc 2.2.2, with some
        portability fixes for use outside glibc, as follows:

        * lib/tempname.c (struct_stat64): New macro.
        (direxists, __gen_tempname): Use it.
        This avoids a portability problem with Solaris 8.

        * lib/tempname.c (<config.h>): Include if HAVE_CONFIG_H.
        (<stddef.h>, <stdint.h>, <string.h>):
        Include only if STDC_HEADERS || _LIBC.
        (<fcntl.h>): Include only if HAVE_FCNTL_H || _LIBC.
        (<unistd.h>): Include only if HAVE_UNISTD_H || _LIBC.
        (<sys/time.h>): Include only if HAVE_SYS_TIME_H || _LIBC.
        (__set_errno): Define this macro if <errno.h> doesn't.
        (P_tmpdir, TMP_MAX, __GT_FILE, __GT_BIGFILE, __GT_DIR, __GT_NOCREATE):
        Define these macros if <stdio.h> doesn't.
        (S_ISDIR, S_IRUSR, S_IWUSR, S_IXUSR):
        Define these macros if <sys/stat.h>
        doesn't.  Ignore <sys/stat.h> S_ISDIR if STAT_MACROS_BROKEN.
        (stat64, __getpid, __gettimeofday, __mkdir, __open, __open64, lxstat64,
        __xstat64): Define if not _LIBC.
        (__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC).
        (__gen_tempname): Invoke gettimeofday only if
        HAVE_GETTIMEOFDAY || _LIBC;
        otherwise, fall back on plain "time".
        Use macros like S_IRUSR | S_IWUSR rather than octal values like 0600.

        * lib/mkstemp.c (__GT_FILE): Define to zero if not defined.

        * lib/mkstemp.c, lib/tempname.c: New files, taken from glibc 2.2.2.

        * m4/jm-macros.m4 (jm_CHECK_ALL_HEADERS): Check for sys/resource.h.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH):
        Use jm_FUNC_MBRTOWC, not AC_CHECK_FUNCS(mbrtowc).
        * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Likewise.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * lib/mbswidth.c, quotearg.c (mbrtowc, mbsinit):
        Remove workaround macros for hosts that have mbrtowc but not
        mbstate_t, as we now insist on proper declarations for both
        before using mbrtowc.

2001-02-17  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Don't check for
        getmntent via AC_CHECK_FUNCS, since that would get a `no' and disrupt
        further attempts by AC_FUNC_GETMNTENT to check with e.g., -lgen on
        UnixWare 7.1.1.

        * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Adapt to use AC_CACHE_CHECK etc.,
        rather than AC_CACHE_VAL.

2001-02-17  Jim Meyering  <meyering@lucent.com>

2001-02-17  Bruno Haible  <haible@clisp.cons.org>

        * lib/mbswidth.h (mbswidth): Also define as macro, to avoid prototype
        clash.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

        * lib/alloca.c (malloc): Undef before defining, since stdlib.h
        may have defined it.  Needed for Encore Umax-3.0.9.16b systems.
        Reported by Mark Hounschell via Paul Eggert.

2001-02-07  Jim Meyering  <meyering@lucent.com>

        * m4/regex.m4 (jm_INCLUDED_REGEX): Add a test for the latest bug.

2001-02-05  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Require autoconf-2.14d (not yet released), because
        it includes the patch required for `large file' support with at least
        HP-UX's 10.20 /bin/cc.

2001-02-03  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Restore prior use of
        AS_IF, now that it works once again (mysteriously).
        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise.

2001-01-30  Jim Meyering  <meyering@lucent.com>

        Don't use filenames that are 8.3-equivalent to "conftest" on DOS.
        * m4/chown.m4: Rename conftestchown to conftest.chown.
        * m4/rename.m4: s/conftestdir/conftest.d1/ and
        s/conftestdir2/conftest.d2/.
        * m4/utimes.m4: s/conftestdata/conftest.data/
        Inspired by Pavel Roskin's change in autoconf.

2001-01-30  Bruno Haible  <haible@clisp.cons.org>

        * lib/config.charset: Update for FreeBSD 4.2.

2001-01-27  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Open-code what was
        a use of AS_IF.
        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise.

2001-01-26  Jim Meyering  <meyering@lucent.com>

2001-01-24  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (mutually_exclusive_p): Don't blindly handle `charset_not'
        as if it was a `charset'.

        to avoid a warning.  Add back 'const' to inptr.

2001-01-20  Jim Meyering  <meyering@lucent.com>

        Be sure that headers are checked before used in code compiled
        for the type checks.
        * m4/jm-macros.m4 (jm_MACROS): Remove all header checks.
        In place of that, invoke jm_CHECK_ALL_TYPES.
        (jm_CHECK_ALL_HEADERS): New functions with the above checks.
        (jm_CHECK_ALL_TYPES): Require jm_CHECK_ALL_HEADERS.
        Alan Iwi reported a build failure on an f300-fujitsu-uxpv4.1_ES;
        The check for ssize_t was mistakenly run before the test for unistd.h.

        The configure-time check for stdbool.h was missing.
        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_HASH.
        (jm_PREREQ_HASH): New function.

2001-01-17  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Use AS_IF, not AS_IFELSE,

        From Bruno Haible.

2001-01-14  Jim Meyering  <meyering@lucent.com>

        Remove directories in the script, not in the C code.
        Remove conftestdir{,2} before trying to create the directory.
        Make the entire configure script fail if the mkdir fails.

        * lib/rename.c: New file.  From Volker Borchert.
        Include stdlib.h, string.h or strings.h, and xalloc.h.
        Use strip_trailing_slashes rather than open-coding it.

2001-01-03  Paul Eggert  <eggert@twinsun.com>

        * lib/strftime.c: Sync with glibc time/strftime.c 1.81.

        * lib/unicodeio.c (print_unicode_char): Remove `const' from declaration
        of local `inptr' to avoid warning with some system declarations of

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Include utmp.h (if available),
        even on systems with utmpx.h.  It's necessary for the declaration of
        utmp's ut_user member.  Reported by Andreas Jaeger.

        * m4/check-decl.m4 (jm_CHECK_DECLS): Include grp.h and pwd.h if
        available. They are required for the declarations of getgrgid and
        getpwuid resp.

        Reported by Andreas Jaeger.

2001-01-01  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/libintl.m4 (AM_GNU_GETTEXT): Define MKINSTALLDIRS by
        expanding the value of $ac_aux_dir, as in AM_MISSING_HAS_RUN,
        so `make install' also works in VPATH builds.

2000-12-31  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * m4/libintl.m4 (AM_WITH_NLS): When using AC_CONFIG_AUX_DIR,
        prepend $(top_srcdir) to the value of MKINSTALLDIRS so that it
        can be used in subdirectories.

2000-12-29  Paul Eggert  <eggert@twinsun.com>

        * lib/modechange.c: Do not assume that mode_t uses the
        traditional octal encoding.  E.g. "chmod 1 FOO" should set
        the other-execute bit of FOO even if S_IXOTH != 1.

        (SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
        WOTH, XOTH, ALLM): New macros.

        Use them.
        (S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
        (S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
        (mode_compile):
        No need to use uintmax_t; unsigned long is long enough.
        Don't bother to get suffix since we don't use it.

2000-12-26  Jim Meyering  <meyering@lucent.com>

        * m4/dos.m4 (jm_AC_DOS): Rewrite (though it's still a stub) to work
        better with autoheader.

2000-12-24  Jim Meyering  <meyering@lucent.com>

        * lib/hash.c (is_prime): Return explicit boolean values.

2000-12-16  Jim Meyering  <meyering@lucent.com>

        This bug had a serious impact on chown: `chown N:M FILE' (for integer
        N and M) would have treated it like `chown N:N FILE'.

        * lib/userspec.c (parse_user_spec): Fix typo: s/u/g/.

2000-12-16  Jim Meyering  <meyering@lucent.com>

        * lib/getusershell.c [!SHELLS_FILE && __DJGPP__]: Define

        CP1257 to the list of canonical encodings. Rename EUC-CN to GB2312.

2000-12-08  Andreas Schwab  <schwab@suse.de>

        * lib/mbswidth.c (mbsnwidth): Don't loop endlessly when called with an
        invalid mulitbyte sequence and with the MBSW_ACCEPT_INVALID flag set.

2000-12-07  Jim Meyering  <meyering@lucent.com>

        (strip_trailing_slashes): Use ISSLASH rather than comparing against
        `/'.
        From Prashant TR.

        * lib/dirname.c (FILESYSTEM_PREFIX_LEN): Define.
        (dir_name_r): Declare this function as static.
        [BACKSLASH_IS_PATH_SEPARATOR]: Fix a bug that'd
        manifest itself on a name containing a mix of slashes and
        backslashes.
        Make this function work with names starting with a DOS-style
        drive letter and colon prefix.

2000-12-06  Jim Meyering  <meyering@lucent.com>

        * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): If we need the
        replacement strtoull, we may well need the replacement strtoul, too.
        Check for declarations of strtoul and strtoull.
        Check for strtol.  Mainly as a cue to cause automake to include
        strtol.c -- that file is included by each of strtoul.c and strtoull.c.
        Check for limits.h -- strtol.c needs it.

2000-12-05  Jim Meyering  <meyering@lucent.com>

        * lib/dirname.c (dir_name_r): Add `const' in a few local declarations.

2000-12-04  Jim Meyering  <meyering@lucent.com>

        * lib/memcoll.c: Include sys/types.h.  From Werner Almesberger.

2000-11-22  Paul Eggert  <eggert@twinsun.com>

        * lib/strftime.c (my_strftime): Do not invoke mbrlen with a
        size of (size_t) -1; it's not portable.

2000-11-17  Jim Meyering  <meyering@lucent.com>

        * lib/strstr.c: Update from GNU libc.

2000-11-17  Akim Demaille  <akim@epita.fr>

        * lib/obstack.h: Formatting changes.
        (obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
        prevent type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'
        variable is valid.
        (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

2000-11-16  Jim Meyering  <meyering@lucent.com>

        * lib/strverscmp.c: Incorporate weak-alias-related changes from glibc.

2000-11-11  Jim Meyering  <meyering@lucent.com>

2000-11-06  Paul Eggert  <eggert@twinsun.com>

        * lib/getusershell.c (setusershell): Use rewind rather than
        fseek/fseeko, to avoid configuration hassles with fseeko.
        Don't bother opening SHELLS_FILE if shellstream is NULL;
        it's not necessary.

2000-11-05  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.h (make_dir): Declare.
        * lib/makepath.c (make_dir): Remove `static' attribute.

2000-11-04  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * lib/hash.c (hash_get_next): Fix a thinko:  when ENTRY is the
        last one in a bucket, advance to the next bucket.

2000-11-02  Vesselin Atanasov  <vesselin@bgnet.bg>

        * lib/fnmatch.c: Do not comment out all the code if we are using
        the GNU C library, because in some cases we are replacing buggy
        code in the GNU C library itself.

2000-10-30  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (re_iswctype, re_wctype_to_bit): Fix braino.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * lib/fnmatch.c (FOLD): Do not assume that characters are unsigned.
        (fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,
        e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * lib/error.h, getline.h, modechange.h:
        Remove "2000" from Copyright line, as the file hasn't been
        changed this year other than in the copyright notice.

        * lib/xalloc.h: Add "2000" to Copyright line, as this file
        was changed this year.

2000-10-29  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4: s/AC_SHELL_IFELSE/AS_IFELSE/ to match autoconf

2000-10-29  Greg Louis  <glouis@dynamicro.on.ca>

        * lib/regex.h (__restrict_arr): Move definition out of #ifndef block.
        Required because egcs-2.91.66 (aka 1.1.2) defines __restrict, but
        doesn't define __restrict_arr.

2000-10-28  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_MEMCHR.

        [HAVE_STDLIB_H]: Include stdlib.h.
        [HAVE_BP_SYM_H || _LIBC]: Guard inclusion of bp-sym.h.
        Undef __memchr, too.

        * lib/regex.h: Likewise.
        * lib/getopt1.c: Likewise.
        * lib/memcmp.c: Likewise.

        * lib/getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.
        Avoid using fseek, when possible -- it's broken by design.
        Patch by Ulrich Drepper.

2000-10-27  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (POP_FAILURE_REG_OR_COUNT, re_match_2_internal)
        (re_match_2_internal, re_match_2_internal, re_match_2_internal):

2000-10-26  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c: Update from libc.

2000-10-25  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c: More `unsigned char' -> `re_char' changes.
        Also change several `int' into `re_wchar_t'.
        (PATTERN_STACK_EMPTY, PUSH_PATTERN_OP, POP_PATTERN_OP): Remove.
        (PUSH_FAILURE_POINTER): Don't cast any more.
        (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'.
        We want GCC to complain, since this piece of code makes
        re_match non-reentrant, which *should* be fixed.
        (GET_BUFFER_SPACE): Use size_t rather than unsigned long.
        (EXTEND_BUFFER): Use RETALLOC.
        (SET_LIST_BIT): Don't cast.
        (re_wchar_t): New type.
        (re_iswctype, re_wctype_to_bit): Make it crystal clear to GCC
        that those two functions will always properly return.
        (IMMEDIATE_QUIT_CHECK): Cast to void.
        (analyse_first): Use recursion rather than an explicit stack.
        (re_compile_fastmap): Can't fail anymore.
        (re_search_2): Don't check re_compile_fastmap for failure.
        (PUSH_NUMBER): Renamed from PUSH_FAILURE_COUNT.
        Now also sets the new value (passed in a new argument).
        (re_match_2_internal): Use it.
        Also, use a new var `reg' of type size_t when looping through regs
        rather than reuse the inappropriate `mcnt'.

2000-10-25  Jim Meyering  <meyering@lucent.com>

        * lib/obstack.c: Update from libc.

2000-10-24  Kenichi Handa  <handa@etl.go.jp>

        * regex.c (regex_compile): Change the way of handling a range from
        a char less than 256 to a char not less than 256.

2000-10-24  Andrew Innes  <andrewi@gnu.org>

        * regex.c (IMMEDIATE_QUIT_CHECK): New macro, which does QUIT on
        NT-Emacs only.
        (re_match_2_internal): Use IMMEDIATE_QUIT_CHECK instead of QUIT,
        so that re_search functions only quit when callers expect them to.

2000-10-23  Jim Meyering  <meyering@lucent.com>

        * lib/hard-locale.c (hard_locale): Revert last change -- it was simply
        wrong.  That set_locale call must not have any side effects.
        From Paul Eggert.

2000-10-22  Jim Meyering  <meyering@lucent.com>

        * lib/md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.
        [CYCLIC]: Remove now-unused definition.

        * lib/save-cwd.c (O_DIRECTORY): Define, if needed.
        (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".".
        Suggestion from Ulrich Drepper.

2000-10-21  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4 (jm_CHECK_DECLS): Also check for memrchr.

        * lib/dirname.c (memrchr): Declare if necessary.
        (dir_name): Remove the restriction that there be no
        trailing slashes.  Now, this code skips past them, effectively
        ignoring them.
        [TEST_DIRNAME] (main): New unit tests.

        * lib/memrchr.c: New file from GNU libc.
        Undef __memrchr, too.
        [!weak_alias]: Define __memrchr to memrchr.

        * m4/check-decl.m4: Include utmp.h `#if HAVE_UTMP_H', rather than
        `#if !HAVE_UTMPX_H'.  The latter would lose on systems with neither
        utmp.h nor utmpx.h.  Reported by Eli Zaretskii.

2000-08-11  J. David Anglin  <dave@hiauly1.hia.nrc.ca>

        (xrealloc): Comment fix.

        * lib/userspec.c (parse_user_spec):
        Don't translate a message until just before returning,
        to avoid unnecessary translation.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Jim Meyering.

        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c:
        Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        so that mbstate_t is always defined.

        Do not inspect MB_LEN_MAX, since it's incorrectly defined to
        be 1 in at least one GCC installation, and this configuration
        error is likely to be common.  Ignoring MB_LEN_MAX hurts
        performance on hosts that have mbrtowc but have only unibyte
        locales, but I assume these hosts are rare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * lib/mbswidth.c (_XOPEN_SOURCE):

2000-07-23  Bruno Haible  <haible@clisp.cons.org>

        from tar's src/misc.c.
        * lib/quote.h: New file.  Prototypes for same.

2000-07-14  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * lib/quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

        * lib/quotearg.c (quoting_style_args, quoting_style_vals,
        quotearg_buffer_restyled): Add support for
        clocale_quoting_style.  Undo previous change to
        locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
        and "{RIGHT QUOTATION MARK}" msgids.

2000-07-10  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * m4/mbstate_t.m4 (AC_MBSTATE_T):
        Renamed from AC_MBSTATE_T_OBJECT.  All uses changed.
        Change from a two-part test, which defines both HAVE_MBSTATE_T_OBJECT
        and mbstate_t, to a single-part test that simply defines mbstate_t.
        * m4/prereq.m4 (jm_PREREQ_QUOTEARG):
        s/AC_MBSTATE_T_OBJECT/AC_MBSTATE_T/.

2000-07-10  Jim Meyering  <meyering@lucent.com>

        * m4/strerror_r.m4: Mirror the correction made in autoconf.

        * m4/gnu-source.m4: Output to confdefs.h directly.
        Suggestion from Akim Demaille.

2000-07-09  Paul Eggert  <eggert@twinsun.com>

        The old behavior of quoting `like this' doesn't look good with
        newer, ISO-style fonts.  See:
        http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

        Instead, quote "like this" by default.  Let the translator
        tailor the locale-specific quoting behavior by providing
        translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

        * lib/quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use
        gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
        gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.

2000-07-09  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_MACROS): Add a test to see if -lm is required

        * m4/gnu-source.m4 (AC__GNU_SOURCE): New file/macro.

2000-07-05  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Test for mbstate_t
        only if the test for an object-type mbstate_t fails.  This
        prevents us from mistakenly reporting that mbstate_t is a
        system object type after we "#define mbstate_t int" to work
        around its lack.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * lib/xgethostname.c (xgethostname): Protect against the SunOS 5.5 bug
        by allocating a larger buffer. Test the gethostname return value for
        being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
        returns an error and ENAMETOOLONG isn't defined.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * lib/strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
        Reported by Bruno Haible.

2000-07-04  Jim Meyering  <meyering@lucent.com>

        * lib/quotearg.c: Make inclusion of <wchar.h> independent of whether
        HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
        lacks mbrtowc.

2000-07-03  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Port to autoconf 2.13.

        HP-UX 10.20.
        From Bob Proulx.

2000-07-01  Jim Meyering  <meyering@lucent.com>

        * m4/ls-mntd-fs.m4: Remove a `FIXME' comment and fix the associated
        problem.

2000-07-01  Bruno Haible  <haible@clisp.cons.org>

        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Rename BeOS specific
        macro from MOUNTED_NEXT_DEV to MOUNTED_FS_STAT_DEV.

2000-07-01  Bruno Haible  <haible@clisp.cons.org>

        * lib/mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV,
        per change in ../m4/ls-mntd-fs.m4.
        (read_filesystem_list): Ignore symbolic links.

2000-06-29  Jim Meyering  <meyering@lucent.com>

        * lib/same.c: Include <string.h> or <strings.h>, as appropriate,
        for declaration of strcmp.

        * lib/long-options.c: Include <stdlib.h>, for declaration of exit.

        * lib/mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]:
        Avoid warning by casting result to `char *' to remove `const'.

2000-06-28  Jim Meyering  <meyering@lucent.com>

        * m4/mbstate_t.m4: Use stdlib.h, not stdio.h.  The latter is not
        included by quotearg.c, for which we perform this test.  From
        Bruno Haible.

2000-06-27  Bruno Haible  <haible@clisp.cons.org>

        * m4/check-decl.m4 (_jm_DECL_HEADERS): Check for utmp.h as well.
        * m4/prereq.m4 (jm_PREREQ_READUTMP): Likewise. If either <utmp.h> or

2000-06-27  Bruno Haible  <haible@clisp.cons.org>

        * lib/Makefile.am (libfetish_a_SOURCES): Remove readutmp.c.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        savedir now sets errno on failure and invokes xmalloc to get memory.
        Fix a couple of other minor bugs while we're at it.

        * lib/savedir.c (<unistd.h>): Do not include; there's no need.
        (NAMLEN): Remove macro.
        (malloc, realloc): Remove decls.
        (stpcpy): Likewise.
        ("xalloc.h"): Include.
        (NAME_SIZE_DEFAULT): New macro.
        (savedir): Use xmalloc / xrealloc to allocate memory.
        Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero.
        Skip "" directory entries.
        Use strlen to calculate directory entry length, since the old method
        is rarely used these days and isn't worth supporting.
        Don't use a pointer after freeing it.
        Check for integer overflow when calculating allocation size.
        Use memcpy to copy entries, instead of stpcpy.
        Set errno properly when returning NULL.
        Check for readdir error.

2000-06-26  Jim Meyering  <meyering@lucent.com>

        * lib/posixtm.c [HAVE_STDLIB_H]: Include stdlib.h, for decl of abort.

2000-06-25  Jim Meyering  <meyering@lucent.com>

        * m4/mbstate_t.m4: Include stdio.h before wchar.h to work around
        Linux header bug when _XOPEN_SOURCE is defined to 500.

        * lib/unicodeio.c (print_unicode_char): Work around ansi2knr
        deficiency.

        * lib/getusershell.c (xmalloc, xrealloc): Remove functions.
        Include xalloc.h.
        Don't include <stdlib.h>.  Don't declare malloc, realloc.

2000-06-24  Jim Meyering  <meyering@lucent.com>

        * m4/strerror_r.m4: Revive this file -- to try out an experimental
        version of AC_FUNC_STRERROR_R that may work even on BeOS, a system
        for which strerror does return char*, but which lacks a conveniently
        accessible declaration of the function.  If the compile-test says
        strerror_r doesn't work, then resort to a `run'-test that works on
        BeOS and segfaults on DEC Unix.

2000-06-24  Jim Meyering  <meyering@lucent.com>

        * lib/error.c [!HAVE_DECL_STRERROR_R]: Declare strerror_r.

2000-06-23  Paul Eggert  <eggert@twinsun.com>

        HAVE_MBRTOWC && HAVE_WCHAR_H && !HAVE_MBSTATE_T_OBJECT.
        (iswprint): Define to 1 if !defined iswprint && !HAVE_ISWPRINT,
        not if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).

2000-06-23  Jim Meyering  <meyering@lucent.com>

        * m4/afs.m4: Add missing AC_MSG_RESULT.
        Reported by Bruno Haible.

        * m4/fsusage.m4: s/AC_MSG_CHECKING/AC_CHECKING/.
        Suggestion from Bruno Haible.

        * lib/getline.c (getstr): Move into a separate file.
        * lib/getstr.c (getstr): New file, extracted from getline.c, with
        the following changes: new parameter, delim2; both delim[12]
        parameters have type `int', not `char'.  The latter would lose
        with 8-bit delimiters.
        * lib/getstr.h: New file.

2000-06-21  Bruno Haible  <haible@clisp.cons.org>

        * lib/xgetcwd.c (xgetcwd): If the required pathname length is smaller
        than 1024, return a memory chunk of least possible size, instead
        of size PATH_MAX + 2. In the loop, increment the size proportionally.
        Use free/xmalloc instead of xrealloc to avoid copying for very long
        paths.

2000-06-21  Bruno Haible  <haible@clisp.cons.org>

        * lib/path-concat.c (path_concat): Don't access dir[-1] if dir is
        the empty string.

        `checking whether...' message to be consistent with that of the
        lstat test.

2000-06-18  Jim Meyering  <meyering@lucent.com>

        * lib/mkdir.c: Remove file, due mainly to copyright incompatibility.
        Besides, these days every porting target provides a mkdir function.

        * lib/strnlen.c: Include memory.h, string.h, and/or strings.h as
        needed. (this snippet comes from src/system.h).

2000-06-16  Bruno Haible  <haible@clisp.cons.org>

        * m4/glibc21.m4 (jm_GLIBC21): Define GLIBC21 for Makefiles, not for C.

        size that is not a multiple of the output block size, and vice versa.
        Reported by Piergiorgio Sartor.

        * lib/xstat.in [!HAVE_DECL_FREE]: Declare free in lstat.c.

2000-06-12  Paul Eggert  <eggert@twinsun.com>

        * lib/xstat.in: Include <stdlib.h> in lstat, to declare "free".

2000-06-12  Jim Meyering  <meyering@lucent.com>

        * m4/getloadavg.m4 (AM_FUNC_GETLOADAVG): Replace with
        AC_FUNC_GETLOADAVG from autoconf, and tweak the latter to accept an
        optional argument.
        * m4/jm-macros.m4: s/AM_FUNC_GETLOADAVG/AC_FUNC_GETLOADAVG/, and supply
        the optional argument, `lib'.

2000-06-08  Jim Meyering  <meyering@lucent.com>

        * m4/largefile.m4: Remove file (now that it's part of autoconf).

2000-06-04  Paul Eggert  <eggert@twinsun.com>

        Rewrite largefile configuration so that we don't need to run
        getconf and don't need AC_CANONICAL_HOST.  [I'm leaving the use of
        AC_CANONICAL_HOST in configure.in -- jmm]

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS,
        AC_SYS_LARGEFILE_SPACE_APPEND): Remove.
        (AC_SYS_LARGEFILE_TEST_INCLUDES): New macro.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Change arguments from
        CODE-TO-SET-DEFAULT to VALUE, INCLUDES, FUNCTION-BODY.
        All uses changed.
        Instead of inspecting the output of getconf, try to compile the
        test program without and with the macro definition.
        (AC_SYS_LARGEFILE): Do not require AC_CANONICAL_HOST or check
        for getconf.  Instead, check for the needed flags by compiling
        test programs.

        * m4/prereq.m4 (jm_PREREQ_HUMAN): Use []-quoted list in AC_CHECK_DECLS,
        now that autoconf requires that.

        #undefs.  E.g., #undef HAVE_DECL_FERROR_UNLOCKED.
        Use []-quoted list in AC_CHECK_DECLS, now that autoconf requires that.

        (hash_delete): Rewrite to use neither the assignment operator
        nor the comma operator in an if-expression.

        Remove; no longer needed.
        "quotearg.h": Add include.
        (file_name): Do not bother to explicitly initialize to NULL; it's less
        efficient on some hosts.
        (close_stdout_status): Remove test as to whether stdout was already
        closed; it breaks for the case "echo x | sort >&-".
        Quote file name colons.
        Do not assume that _("write error") lacks format strings.

2000-05-15  Jim Meyering  <meyering@lucent.com>

        be 500, instead of _GNU_SOURCE to be 1, to work around glibc
        2.1.3 bug.  This avoids a clash when files like regex.c define
        _GNU_SOURCE.

        * m4/largefile.m4 (AC_SYS_LARGEFILE): Define _GNU_SOURCE if
        this is needed to make ftello visible (e.g. glibc 2.1.3).  Use
        compile-time test, rather than inspecting host and OS, to
        decide whether to define _LARGEFILE_SOURCE.

2000-05-01  Jim Meyering  <meyering@lucent.com>

        * m4/fsusage.m4: Use AC_MSG_CHECKING instead of obsolete AC_CHECKING.

2000-04-28  Jim Meyering  <meyering@lucent.com>

        * lib/rpmatch.c [HAVE_LIMITS_H]: Include limits.h before regex.h to
        avoid redefinition warning on some systems (HPUX).  Otherwise, regex.h
        is included first, then limits.h is included by locale.h by libintl.h.
        From John David Anglin.

        of the `special' permission bits.  Prompted by a bug report against
        install from Mate Wierdl and Joost van Baal.

2000-04-18  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_GETPAGESIZE): New macro.
        (jm_PREREQ): Use it.

2000-04-18  Jim Meyering  <meyering@lucent.com>

        * lib/README: New file.

        * lib/getpagesize.h [!getpagesize && HAVE_OS_H && B_PAGE_SIZE]: Define
        getpagesize.  For BeOS.  Based on a patch from Bruno Haible.

2000-04-17  Jim Meyering  <meyering@lucent.com>

        Get it right :-)
        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Emit the
        actual #define via AH_VERBATIM.  Don't need separate AC_DEFINE.
        Suggestion from Akim Demaille.

2000-04-17  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c (my_strftime) [strftime]: Declare strftime here, since
        the definition of it to rpl_strftime also defined-away the system's
        declaration.

2000-04-15  Jim Meyering  <meyering@lucent.com>

        Use `C' to denote so-called `contiguous' files, the same way
        that tar does.
        * lib/filemode.c (S_ISCTG) [!S_ISCTG && S_IFCTG]: Define.
        (ftypelet): Use S_ISCTG.
        From Michael Deutschmann.

2000-04-14  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Use the one-arg
        form of AC_DEFINE.  Otherwise, the #ifndef in AH_VERBATIM gets
        clobbered.

2000-04-14  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c (my_strftime) [#ifdef strftime]: Declare strftime.

2000-04-13  Jim Meyering  <meyering@lucent.com>

        AH_VERBATIM to insert required #ifndef into config.h.in.
        Suggestion from Akim Demaille.

2000-04-12  Jim Meyering  <meyering@lucent.com>

        * m4/getloadavg.m4 (AM_FUNC_GETLOADAVG): Use AC_CHECK_HEADERS, not
        `AC_CHECK_HEADER' to check for locale.h.  Thanks to a report from
        Christian Krackowizer.

        More code moved from ../configure.in into (jm_CHECK_ALL_TYPES).
        * m4/jm-macros.m4 (_GNU_SOURCE): Define.
        (AC_SYS_LARGEFILE): Require.
        (AM_C_PROTOTYPES): Require.

2000-04-08  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (charset.alias): Use t-$@, not $@-t so the DOS 8.3
        names don't conflict.  Reported by Eli Zaretskii.

2000-04-07  Jim Meyering  <meyering@lucent.com>

        * lib/putenv.c: Move inclusion of errno.h so it follows that of
        sys/types.h, to work around system header problems on AIX 3.2.5.
        From Bruno Haible.

2000-04-07  Bruno Haible  <haible@clisp.cons.org>

        * lib/unicodeio.c (print_unicode_char): Avoid triggering Solaris iconv
        bug.  Deal with the different error behavior of Irix iconv.

2000-04-05  Paul Eggert  <eggert@twinsun.com>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Don't use -n32 on
        IRIX if the installer said otherwise.

2000-04-05  Jim Meyering  <meyering@lucent.com>

        Portability tweaks required for ultrix4.3.
        * m4/check-decl.m4 [!HAVE_UTMPX_H] (headers): Include <utmp.h>.
        (jm_CHECK_DECLS): Add getutent to the list of functions.
        (_jm_DECL_HEADERS): Add utmpx.h.
        From John David Anglin.

        * m4/strftime.m4: Back out the 2000-04-02 change.
        Instead of that change, simply undefine putenv in the test program.

2000-04-05  Jim Meyering  <meyering@lucent.com>

        Portability tweaks required for ultrix4.3.
        * lib/readutmp.h [HAVE_UTMPX_H && !HAVE_DECL_GETUTENT]: Declare
        getutent.
        * lib/readutmp.c: Include sys/types.h before sys/stat.h.

        * lib/path-concat.c: Likewise.
        From John David Anglin.

2000-04-04  Jim Meyering  <meyering@lucent.com>

        Be more DOS 8.3-friendly.
        * lib/ref-add.sin: Renamed from ref-add.sed.in.
        * lib/ref-del.sin: Renamed from ref-del.sed.in.
        * lib/Makefile.am: Reflect renaming.
        Reported by Eli Zaretskii.

        Use a temporary file name that won't clash with `charset.alias'
        in the DOS 8.3 name space.
        * lib/Makefile.am (charset_tmp): Define.
        (install-exec-local): Use $(charset_tmp) instead of $(charset_alias)-t.

        * m4/codeset.m4 (AC_CHECK_HEADERS): Add langinfo.h (moved here from
        textutils/configure.in).  Suggestion from Paul Eggert.
        (AC_CHECK_FUNCS): Add nl_langinfo.  (also from textutils/configure.in)

2000-04-02  Paul Eggert  <eggert@twinsun.com>

        * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME): Set TZ environment
        variable in the shell rather than using putenv, which isn't
        portable.  This avoids the configure-time inter-test dependency
        on the potentially-renamed putenv function.

2000-03-30  Paul Eggert  <eggert@twinsun.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Include <sys/stat.h>
        before checking struct stat.st_blksize, so that
        HAVE_STRUCT_STAT_ST_BLKSIZE is defined correctly.

2000-03-29  Paul Eggert  <eggert@twinsun.com>

        * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Check for strftime,
        since strftime.c uses HAVE_STRFTIME to decide whether to use
        the underlying strftime.

2000-03-29  Paul Eggert  <eggert@twinsun.com>

        * lib/time/strftime.c (my_strftime): Make sure we call the system
        strftime, not ourselves, when invoking the underlying strftime.

2000-03-24  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (EXTRA_DIST): Add ref-add.sed.in and ref-del.sed.in.
        (charset_alias): Define.
        (install-exec-local): Factor out common code.
        (uninstall-local): Split lines longer than 80.
        (ref-add.sed, ref-del.sed): Remove rules... (do the following instead)

        (print_unicode_char): Pass the Unicode character to iconv in UTF-8
        format instead of in UCS-4 with platform dependent endianness.

2000-03-10  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: Look for getspnam in -lgen, too.
        From Marco Franzen.

2000-03-07  Paul Eggert  <eggert@twinsun.com>

        * lib/savedir.c (savedir): Work even if directory size is
        negative; this can happen with some screwy NFS configurations.

2000-03-06  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c (get_charset_aliases): Don't try to free file_name
        if it's NULL (because we ran out of memory).  From Bruno Haible.

2000-03-05  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c ("path-concat.h"): Include.
        (get_charset_aliases): Use path_concat instead of ANSI string
        concatenation.

        * lib/unicodeio.h (PARAMS): Define.
        Use it to guard prototype.

2000-03-04  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require AC_C_VOLATILE,
        for lib/localcharset.c.

2000-03-04  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (install-exec-local): Create $(libdir) before
        installing into it.
        (uninstall-local): Uncomment this rule so `make distcheck' works
        once again.

        * lib/unicodeio.c (<errno.h>): Include it.
        (errno): Declare if not defined.

        * lib/localcharset.c: Add Bruno's comment justifying use of volatile.

        * lib/config.charset: New version, incorporating remarks from a linux
        i18n mailing list.  From Bruno Haible.

2000-03-04  Bruno Haible  <haible@clisp.cons.org>

        * m4/codeset.m4: New file.
        * m4/iconv.m4: New file.
        * m4/jm-macros.m4 (jm_MACROS): Call jm_LANGINFO_CODESET and jm_ICONV.

2000-03-02  Jim Meyering  <meyering@lucent.com>

        * m4/timespec.m4: Require AC_HEADER_TIME before the cache check so
        the messages come out on separate lines.

        * m4/jm-glibc-io.m4 (jm_FUNC_GLIBC_UNLOCKED_IO): Use AC_CHECK_DECLS,
        rather than jm_CHECK_DECLARATIONS.
        * m4/decl.m4: Remove now-unused file.

        * m4/check-decl.m4 (AC_CHECK_DECLS): Add getlogin, ttyname, and
        geteuid.

2000-03-02  Jim Meyering  <meyering@lucent.com>

2000-03-01  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c: Guard some #includes with `#if HAVE_...'.

        (noinst_HEADERS): Add unicodeio.h.
        (all-local, install-exec-local, charset.alias): New targets.

2000-02-28  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (ALERT_CHAR): New macro.
        (quotearg_buffer_restyled): Use it.

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4: Add getenv to the list.

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * lib/strtoumax.c: Fix typo in decl of strtoul: s/long long/long/.
        Guard declaration of strtoull also with `&& HAVE_UNSIGNED_LONG_LONG'.

        * lib/backupfile.c: Guard inclusion of stdlib.h with
        `#if HAVE_STDLIB_H', not `#if STDC_HEADERS'.
        Declare malloc if needed.

        * lib/backupfile.c: Use `#if !HAVE_DECL...' instead of
        `#ifndef HAVE_DECL..'
        now that autoconf always defines the HAVE_DECL_ symbols.
        * lib/human.c: Likewise.
        * lib/same.c: Likewise.
        * lib/strtoumax.c: Likewise.

        * lib/backupfile.c: Arrange for cpp to fail if the configure-time
        declaration check was not run.
        * lib/hash.c: Likewise.
        * lib/human.c: Likewise.
        * lib/same.c: Likewise.
        * lib/strtoumax.c: Likewise.

        * lib/userspec.c (parse_user_spec): If there is no `:' but there is a
        `.', then first look up the entire `.'-containing string as a login
        name.

2000-02-23  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4: Now that we have the new AC_CHECK_DECLS, use it
        in place of my hack.

2000-02-18  Paul Eggert  <eggert@twinsun.com>

        * lib/getdate.y: Handle two-digit years with leading zeros correctly.
        (textint): New typedef.
        (parser_control): Member year changed from int to textint.
        All uses changed.
        (YYSTYPE): Removed; replaced by %union with int and textint members.
        (tDAY, tDAY_UNIT, tDAYZONE, tHOUR_UNIT, tID, tLOCAL_ZONE, tMERIDIAN,
        tMINUTE_UNIT, tMONTH, tMONTH_UNIT tSEC_UNIT, tSNUMBER, tUNUMBER,
        tYEAR_UNIT, tZONE, o_merid): Now of type <intval>.

        (yylex): Store number of digits of numeric tokens.
        Reported by John Kendall.

        (parser_control): Changed from struct parser_control to typedef (for
        consistency).  All uses changed.

        (tID): Removed; not used.
        (yylex): Return '?' for unknown identifiers, rather than (unused) tID.

2000-02-14  Paul Eggert  <eggert@twinsun.com>

        * lib/getpagesize.h (getpagesize): Port to VMS for Alpha;
        adapted from changes to grep getpagesize.h by Martin P.J. Zinser.

2000-02-12  Jim Meyering  <meyering@lucent.com>

        * lib/userspec.c (ISDIGIT): Define it.
        (isdigit): Remove definition.
        (is_number): Use ISDIGIT, not isdigit.
        <libintl.h>: Include.
        (_ and N_): Define.
        (parse_user_spec): Mark translatable strings.

2000-02-10  Jim Meyering  <meyering@lucent.com>

        With these changes, nanosleep.[ch] are finally enough like the other
        lib/* replacement files to compile on a few more losing systems.

        * lib/nanosleep.h: Don't include config.h.
        Remove prototype from declaration of nanosleep.
        (PARAMS): Remove now-unneeded definition.
        * lib/nanosleep.c: #undef nanosleep.
        (rpl_nanosleep): Rename from nanosleep.

2000-02-10  Jim Meyering  <meyering@lucent.com>

        * m4/nanosleep.m4 (jm_FUNC_NANOSLEEP): Rename replacement function from
        gnu_nanosleep to rpl_nanosleep.

2000-02-09  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4 (jm_LIB_CHECK): Fix typo: check for sp_pwdp in
        struct spwd, rather than in struct passwd.  Reported by Gaël Quéri.

2000-02-08  Akim Demaille  <akim@epita.fr>

        * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Quote square brackets with
        `[' and `]' and remove uses of `changequote'.
        (AC_SYS_LARGEFILE_MACRO_VALUE): Likewise.

2000-02-05  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require most macros.
        Remove explicit use of AC_HEADER_TIME.  It is required by
        jm_CHECK_TYPE_STRUCT_TIMESPEC.  Using AC_HEADER_TIME and
        `AC_REQUIRE'ing jm_CHECK_TYPE_STRUCT_TIMESPEC provoked a but
        in autoconf whereby the expansion of the latter ended up preceding
        the expansion of its prerequisite, AC_HEADER_TIME.
        Reported by Volker Borchert.

2000-02-03  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_READUTMP): Check for utmpxname.

2000-02-03  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.c (read_utmp): Guard with `#ifdef UTMP_NAME_FUNCTION',
        rather than with `#if HAVE_UTMPNAME'.

2000-02-02  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4 (jm_PREREQ_ADDEXT): Fix typo that resulted in no
        definition of HAVE_PATHCONF: s/AC_CHECK_FUNC/AC_CHECK_FUNCS/.
        Reported by Eli Zaretskii.

2000-02-01  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.h (UT_USER): Add parens.  From Andreas Schwab.

2000-01-31  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4 (jm_CHECK_DECLS): Add nanosleep to the list of
        functions.  Add the time.h and sys/time.h headers along with the
        AC_REQUIRE'ment of AC_HEADER_TIME.

2000-01-31  Jim Meyering  <meyering@lucent.com>

        * lib/nanosleep.h (nanosleep): Guard declaration with
        `#if ! HAVE_DECL_NANOSLEEP'.
        Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
        the declaration in that vendor's sys/timers.h.
        Reported by Christian Krackowizer.

        * lib/quotearg.c (ISASCII): Add #undef and move definition to follow
        inclusion of wctype.h to work around Solaris 2.6 namespace pollution.
        (ISPRINT): Likewise.
        Reported by Tom Tromey.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: Clean up some kludgy old shadow password tests.

        * m4/prereq.m4 (utmp_includes): Define.
        Check for ut_user and ut_name members in both struct utmpx
        and struct utmp.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * lib/readutmp.c (extract_trimmed_name): Use UT_USER instead of
        hard-coding uses of ->ut_name.  The latter doesn't work with new Linux
        header files where only utmpx.ut_user is declared.

        * lib/readutmp.h (UT_USER): Define.

2000-01-29  Jim Meyering  <meyering@lucent.com>

        * m4/lib-check.m4: New file containing library-related checks from
        fileutils and sh-utils (textutils had none).

2000-01-28  Jim Meyering  <meyering@lucent.com>

        * m4/perl.m4: Change format of warning message to look more like that
        from the missing script.  Suggestion from François Pinard.

2000-01-25  Jim Meyering  <meyering@lucent.com>

        * m4/timespec.m4: Require AC_HEADER_TIME, and include sys/time.h as
        well as time.h in the compile check.
        * m4/nanosleep.m4: Require AC_HEADER_TIME rather than simply using it.
        Fix typo in cross-compiling case: s/yes/no/.

2000-01-23  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4: Move df-related tests here from
        fileutils/configure.in

        * m4/ls-mntd-fs.m4: s/list_mounted_fs/ac_list_mounted_fs/
        (jm_LIST_MOUNTED_FILESYSTEMS): Take two parameters.

        * m4/fsusage.m4: New file.  Extracted from fileutils/configure.in.
        s/space/ac_fsusage_space/.
        (jm_FILE_SYSTEM_USAGE): Take two parameters.

        * m4/check-decl.m4: Use the new 3-arg form of AC_DEFINE instead of the

        * m4/regex.m4: By default, don't use the included regex.c on systems

        cache-check for the same variable -- that defeated the purpose of
        the test; the test program was never run.  This was a problem only
