        * lib/acl.c: Move header inclusions and related macro defns into

        Call acl_trivial if available.  This is the crucial part of the fix.
        (acl_entries): Move to lib/acl_entries.c.  Now extern, since it's
        shared within the library.  Rewrite a bit, partly to make it compatible
        with the GNU coding style.
        * m4/acl.m4 (AC_FUNC_ACL): Add AC_LIBOBJ([file-has-acl]).
        Remove unnecessary double-quotes.
        Don't test for acl_to_text; the build will catch that.
        Replace acl_entries if it doesn't exist and it is needed.
        Check for -lsec and acl_trivial (as used on Solaris 10).
        * modules/acl (Files): Add lib/acl-internal.h, lib/acl_entries.c,
        lib/file-has-acl.c.

        * 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,

        Don't use FD after a successful "fdopendir (fd)".

        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'.
        * lib/time_.h, m4/time_h.m4, modules/time: New files.
        * lib/strptime.h, lib/time_r.h, lib/timegm.h: Remove.

        * lib/timespec.h: Don't include <sys/time.h> before <time.h>;
        time.h now handles any problems in that area.
        (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

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

        * lib/string_.h: If the gnulib module XYZ is not present, undefine
        the symbol XYZ before redefining it.  This fixes a problem with
        programs that don't use XYZ, when compiled on systems that define
        XYZ to something else.

        occurs when "mkdir -m foo" creates a setgid directory that is (1)
        writeable to group or other and (2) is intended to have a special
        mode bit that is set or cleared.  In such a case, the directory
        should be neither group- nor other-writeable until the special
        mode bits are right.

2007-01-20  Jim Meyering  <jim@meyering.net>

        * lib/userspec.c (parse_with_separator): If a user or group string
        starts with "+", skip the corresponding name-to-ID look-up, since
        such a look-up must fail: user and group names may not include "+".

2007-01-19  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/poll.c: Include sys/time.h and time.h unconditionally,

        check for sys/time.h; no longer needed.

2007-01-18  Bruno Haible  <bruno@clisp.org>

        (dummy): Remove variable.

        * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Renamed from
        gl_HEADER_SYS_TIME_H.
        (gl_HEADER_SYS_TIME_H): New macro.

        * lib/sys_time_.h: Test GETTIMEOFDAY_REPLACEMENT instead of
        HAVE_GETTIMEOFDAY_POSIX_SIGNATURE and GETTIMEOFDAY_CLOBBERS_LOCALTIME.
        * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY,
        gl_FUNC_GETTIMEOFDAY_CLOBBER): Set GETTIMEOFDAY_REPLACEMENT instead of

        * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H): Initialize

        and GETTIMEOFDAY_CLOBBERS_LOCALTIME.
        * modules/sys_time (sys/time.h): Substitute GETTIMEOFDAY_REPLACEMENT
        instead of HAVE_GETTIMEOFDAY_POSIX_SIGNATURE and
        GETTIMEOFDAY_CLOBBERS_LOCALTIME.

        * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Undo the
        last change; it caused a compilation error when cross-compiling to
        Cygwin.

2007-01-18  Jim Meyering  <jim@meyering.net>

        Use "$(MKDIR_P) sys", not race-prone "test -d sys || mkdir sys".
        * modules/sys_stat (Makefile.am): Use "$(MKDIR_P) sys", rather

        * modules/sys_select: Likewise.

2007-01-18  Eric Blake  <ebb9@byu.net>

        * 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/nanosleep.m4 (gl_FUNC_NANOSLEEP): 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.

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.

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

        * lib/gettimeofday.c (gettimeofday): Add code for the case

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):

        (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

        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

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

        * 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.

        <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>

        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".

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

              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.

        (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.

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>

        * m4/warning.m4: Use the all-permissive copyright notice

2006-11-28  James Youngman <jay@gnu.org>

        * README: Advise users that they might find the bug-gnulib@gnu.org
        and autotools-announce@gnu.org mailing lists useful.

2006-11-28  Bruno Haible  <bruno@clisp.org>

        * m4/ptrdiff_max.m4: Remove file.

2006-11-21  Bruno Haible  <bruno@clisp.org>

        * m4/eoverflow.m4 (gl_EOVERFLOW): Use AC_COMPUTE_INT instead of

2006-11-28  Jim Meyering  <jim@meyering.net>

        * lib/regcomp.c (parse_branch): Rename local, exp->expr, to avoid

        * lib/regex.h (__restrict_arr): Don't use the [restrict] syntax
        if compiling pedantically with GCC, unless it's C99 or later.
        Don't trust sys/cdefs.h's definition of __restrict_arr, either, as
        it mishandles gcc -ansi -pedantic as well.
        * lib/regex_internal.h (re_token_t): Don't use enum bitfields
        if gcc -pedantic.
        * lib/regexec.c (check_node_accept_bytes): Don't use auto
        initializers for struct if -pedantic, unless it's C99 or later.

2006-11-25  Nix  <nix@esperi.org.uk>  (tiny change)

        * m4/fcntl_h.m4 (gl_FCNTL_H): Test the atime, not the mtime.
        Don't close an fd more than once. Identical atimes indicate
        success, not failure.

2006-11-22  Robinson Mittmann <bob@hoplon.com>  (tiny change)

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

        seems to have the bug.
        * lib/fstatat.c: New file.
        * modules/openat (Files): Add it.

2006-11-20  Bruno Haible  <bruno@clisp.org>

        * Makefile: New file.

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

        The beginnings of syntax-related checks for gnulib.
        * lib/Makefile: New file.
        * lib/t-idcache: New script.  Ensure that the two halves of
        idcache.c stay in sync.

        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.

        Use cleaner syntax: NULL rather than 0.
        * 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.

        * 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>

        random "(cached)" in configure output.

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'.

2006-11-14  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/lib-link.m4 (AC_LIB_LINKFLAGS, AC_LIB_HAVE_LINKFLAGS,
        AC_LIB_LINKFLAGS_BODY): Also set a LIB${NAME}_PREFIX variable. Needed
        for GNOME libraries, for which the include files are installed in
        subdirectories of $prefix/include.

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

        * m4/lib-link.m4: Require at least autoconf-2.54.
        (AC_LIB_LINKFLAGS_BODY) [autoconf < 2.61]: Turn dots into the library

        * 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.
        (func_ln_if_changed, func_create_testdir): Use it instead of "ln -s".

        Finish support for source files in subdirectories.
        * gnulib-tool (func_emit_lib_Makefile_am): If some of the source files
        are in subdirectories, set uses_subdirs and add 'subdir-objects' to
        AUTOMAKE_OPTIONS.

        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.
        * lib/fts.c (RESTORE_INITIAL_CWD): Also call fd_ring_clear.
        (FCHDIR): Add parentheses.
        (fd_ring_check, fd_ring_print) [!FTS_DEBUG]: Define away.
        (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.
        * m4/i-ring.m4: New file.

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.

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

        * lib/fts.c [FTS_DEBUG]: Don't try to print a pointer via %s.

        * lib/gettext.h (dgettext, dcgettext, ngettext) [! ENABLE_NLS]:
        (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

        * lib/quotearg.h (quotearg_free): New decl.
        * lib/quotearg.c (quotearg_free): New function.
        (slot0, nslots, slotvec0, slotvec):

        Sync from Automake.
        * build-aux/gnupload: Add missing 'gnu' to example URL.

        Suggested by Paul Eggert.

2006-11-08  Jim Meyering  <jim@meyering.net>

        * lib/fts.c [!_LGPL_PACKAGE]: Don't include fcntl--.h twice.
        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.

        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>

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.

        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.

        gl_AC_TYPE_LONG_LONG.

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

        Make it possible to #define c_isascii to an alias.
        * 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.

        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.

        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.
        Problem reported by Matthew Woehlke in:

        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 and the like, so that this module is more like its siblings.
        (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

        run on Solaris 10.

        * lib/regex_internal.c (re_string_reconstruct): Handle
        offset < pstr->valid_raw_len && pstr->offsets_needed case.

        now requires it.

        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.

        Include "mkstemp.h".
        Make the _LIBC code resemble glibc original more,

        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-parse.c (__argp_parse) [!_LIBC]: Make sure
        program_invocation_name and program_invocation_short_name are

        * lib/argp.h: Likewise

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

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

        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>

        in func_emit_lib_Makefile_am.
        (func_import): When building a static library libfoo.a, arrange to

        Also:

        2006-09-08  Paul Eggert  <eggert@cs.ucla.edu>
        Add year_2050_test to catch glibc bug 2821
        <http://sourceware.org/bugzilla/show_bug.cgi?id=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.

2006-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/cycle-check.h: Include <stdint.h> unconditionally, since we
        now assume the stdint module.  Do not include inttypes.h.
        * lib/fsusage.h: Likewise.
        * lib/getndelim2.c: Likewise.

        omitted in the 2006-08-17 update.  Problem reported by Jay Youngman.

2006-08-18  Paul Eggert  <eggert@cs.ucla.edu>
            Bruno Haible  <bruno@clisp.org>

        * m4/bison-i18n.m4 (BISON_I18N): Also handle the case where yacc exists

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

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

        * modules/bison-i18n: New file.

        Update from coreutils.

        * lib/__fpending.h: Add copyright notice.

        * 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.
        * lib/fchmodat.c (fchmodat): Likewise.
        (ENOSYS): Remove definition.
        * lib/openat.c: Don't include <errno.h>, now that "openat-priv.h" does
        it.  Don't include "unistd--.h" -- it wasn't ever used.

        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.

2006-08-16  Paul Eggert  <eggert@cs.ucla.edu>

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

        * 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.
        * tests/test-verify.c: Likewise.

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

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/.cppi-disable: Add snprintf.h, socket_.h.
        * 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].

        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.

        (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.

        (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>

        unless someone speaks up.
        Add lib/dirchownmod.c, lib/dirchownmod.h.
        (Depends-on): Remove alloca, chown, save-cwd, dirname.

        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.

2006-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/getloadavg.c: Use __VMS, not VMS.
        * lib/getopt.c: Likewise.
        * lib/getpagesize.h: Likewise.
        * lib/glob.c: Remove most VMS cruft; it hasn't been tested for a while
        and probably does not work.

2006-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/.cppi-disable: Add wcwidth.
        * lib/fnmatch.c (ISBLANK): Remove.  All uses changed to isblank.
        (isblank) [! (defined isblank || HAVE_DECL_ISBLANK)]: New macro.

        (FOLD) [!defined _LIBC]: Remove special case.
        * lib/getdate.y (lookup_word): Remove no-longer-needed call to islower.
        * lib/regex_internal.h (isblank): Depend on HAVE_DECL_ISBLANK, not
        HAVE_ISBLANK.
        * lib/strftime.c (TOLOWER, TOUPPER) [!defined _LIBC]: Remove special
        case.

2006-07-06  Jim Hyslop  <jhyslop@dreampossible.ca>  (tiny change)

        * lib/getaddrinfo.c: Changes to compile under MSVC6: changed
        '#if WIN32_NATIVE' to '#ifdef' & moved WSAAPI macro inside
        brackets.  Other minor changes to suppress some compiler
        warnings.

2006-07-06  Derek R. Price  <derek@ximbiot.com>
        and Paul Eggert  <eggert@cs.ucla.edu>

        * m4/backupfile.m4 (gl_BACKUPFILE): Check for dirent.h, instead
        of invoking obsolescent AC_HEADER_DIRENT macro.
        * m4/d-ino.m4 (gl_CHECK_TYPE_STRUCT_DIRENT_D_INO): Likewise.

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

        * lib/backupfile.c [HAVE_DIRENT_H && ! HAVE_NDIR_H]:
        Don't worry about this obsolete case any more.
        (HAVE_DIR): Remove.  All uses removed; we now assume you can read
        directories.
        * lib/dirfd.h [HAVE_DIRENT_H && ! HAVE_NDIR_H]: Don't
        worry about this obsolete case any more.

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

        * m4/xstrtol.m4 (gl_PREREQ_XSTRTOL): Use AC_CHECK_DECLS_ONCE
        rather than AC_CHECK_DECLS for strtoimax and strtoumax.
        * m4/getusershell.m4 (gl_PREREQ_GETUSERSHELL): Remove; no longer
        needed.
        All uses removed.

        * m4/strtoul.m4 (gl_PREREQ_STRTOUL): Likewise.

        * m4/xstrtol.m4 (gl_PREREQ_XSTRTOL): Likewise.

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

        (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>

        * 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):

        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.

                    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.

        * 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,
        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.  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.

2006-06-28  Derek R. Price  <derek@ximbiot.com>

        Autoconf 2.60 says this stuff was obsolete.

2006-06-28  Bruno Haible  <bruno@clisp.org>

        * modules/wcwidth (Files): Add m4/wchar_t.m4.

2006-06-28  Bruno Haible  <bruno@clisp.org>

        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Also require AC_C_INLINE and
        gt_TYPE_WCHAR_T.

2006-06-28  Bruno Haible  <bruno@clisp.org>

        * lib/wcwidth.h: Declare nothing if !HAVE_WCHAR_T. Provide a fallback
        declaration for wcwidth.

        MinGW.

2006-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * 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>.

        * modules/inet_pton: New file.

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>

2006-06-21  Paul Eggert  <eggert@cs.ucla.edu>

        * 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

        Length arg is now size_t, not Idx.  All uses changed.
        (peek_token): Forward decl now says internal_function.
        (__re_error_msgid, __re_error_msgid_idx):
        Now static rather than extern with attribute_hidden.
        (re_compile_pattern) [!defined _LIBC]: Use K&R-style defn.
        For some reason libc prefers K&R style defns for external functions.
        (regerror) [!defined _LIBC]: Likewise.
        (re_set_syntax, re_compile_fastmap, regcomp, regfree, re_comp):
        (seek_collating_symbol_entry, lookup_collation_sequence_value):
        (build_range_exp, build_collating_symbol):
        Use K&R-style defn.
        (re_compile_fastmap): Use '\0' to memset, not 0.
        (utf8_sb_map): Make the calculations more obvious.
        (init_dfa, parse_bracket_exp, build_charclass_op):
        Call calloc and cast result, as glibc does.
        (init_word_char, fetch_token, peek_token, peek_token_bracket):
        (build_range_exp, build_collating_symbol):
        Now internal functions.

        * lib/regex.c [!defined _LIBC]: Allow compiling with C++ compilers.

        * lib/regex.h (__USE_GNU_REGEX): New macro.  Don't depend on
        _REGEX_SOURCE any more; depend on _GNU_SOURCE instead.
        Don't depend on VMS; depend on __VMS instead, for POSIX
        namespace cleanness.
        (regoff_t): Define to ssize_t, not long int.

        Remove the REG_ macros named below.  Instead, make the old names
        (e.g., RE_BACKSLASH_ESCAPE_IN_LISTS) visible only if
        __USE_GNU_REGEX.
        (REG_BACKSLASH_ESCAPE_IN_LISTS):
        (REG_BK_PLUS_QM, REG_CHAR_CLASSES, REG_CONTEXT_INDEP_ANCHORS):
        (REG_CONTEXT_INDEP_OPS, REG_CONTEXT_INVALID_OPS):

        (REG_IGNORE_CASE, REG_CARET_ANCHORS_HERE):
        (REG_CONTEXT_INVALID_DUP, REG_NO_SUB, REG_SYNTAX_EMACS):
        (REG_SYNTAX_AWK, REG_SYNTAX_GNU_AWK, REG_SYNTAX_POSIX_AWK):
        (REG_SYNTAX_GREP, REG_SYNTAX_EGREP, REG_SYNTAX_POSIX_EGREP):
        (REG_SYNTAX_ED, REG_SYNTAX_SED, _REG_SYNTAX_POSIX_COMMON):
        (REG_SYNTAX_POSIX_BASIC, REG_SYNTAX_POSIX_MINIMAL_BASIC):
        (REG_SYNTAX_POSIX_EXTENDED, REG_SYNTAX_POSIX_MINIMAL_EXTENDED):
        (REG_DUP_MAX, REG_UNALLOCATED, REG_REALLOCATE, REG_FIXED):
        (REG_NREGS):
        Remove.  All uses replaced by the old RE_* names.
        (RE_BACKSLASH_ESCAPE_IN_LISTS):
        (RE_BK_PLUS_QM, RE_CHAR_CLASSES, RE_CONTEXT_INDEP_ANCHORS):
        (RE_CONTEXT_INDEP_OPS, RE_CONTEXT_INVALID_OPS):
        (RE_DOT_NEWLINE, RE_DOT_NOT_NULL, RE_HAT_LISTS_NOT_NEWLINE):
        (RE_INTERVALS, RE_LIMITED_OPS, RE_NEWLINE_ALT):
        (RE_NO_BK_BRACES, RE_NO_BK_PARENS, RE_NO_BK_REFS):
        (RE_NO_BK_VBAR, RE_NO_EMPTY_RANGES):
        (RE_UNMATCHED_RIGHT_PAREN_ORD, RE_NO_POSIX_BACKTRACKING):
        (RE_NO_GNU_OPS, RE_DEBUG, RE_INVALID_INTERVAL_ORD):
        (RE_IGNORE_CASE, RE_CARET_ANCHORS_HERE):
        (RE_CONTEXT_INVALID_DUP, RE_NO_SUB):
        Don't bother having these macros be independent of each others'
        values, since they no longer exist in the POSIX name space.

        Rename the following member names back to their old names,
        unless !__USE_GNU_REGEX.  All uses changed back.
        (buffer): Renamed from re_buffer.

        * lib/regex_internal.h (inline) [__GNUC__ < 3 && defined _LIBC]:
        #define to be empty.
        (ASCII_CHARS): New macro, replacing all uses of 0x80 and/or SBC_MAX / 2
        when that is what is intended.
        (SBC_MAX): Define to UCHAR_MAX + 1, not 256.
        (__re_error_msgid, __re_error_msgid_idx): Remove decls; not needed.
        (MAX): New macro.
        (re_xmalloc, re_calloc, re_xrealloc, re_x2realloc): Remove.
        All uses changed back to re_malloc, etc.  It's now the caller's
        responsibility to check for overflow; all callers changed.
        (re_alloc_oversized, re_x2alloc_oversized, re_xnmalloc, re_xnrealloc):
        (re_x2nrealloc): Remove.
        (free_state): Remove decl.

        * lib/regexc.c (regexec, re_match, re_search, re_match_2, re_search_2):
        (re_set_registers, re_exec):
        Use K&R-style defn.

        2005-12-06  Paolo Bonzini  <bonzini@gnu.org>

        2005-09-30  Ulrich Drepper  <drepper@redhat.com>

        * lib/regex.h: Pretty printing.
        Clean up namespace a bit.

        2005-09-30  Jakub Jelinek  <jakub@redhat.com>

        * lib/regexec.c (update_cur_sifted_state, check_arrival,

        changed.

        2005-09-07  Ulrich Drepper  <drepper@redhat.com>

        * lib/regexec.c (find_recover_state): Remove unnecessary
        initialization.

        (get_subexp): Likewise.

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/regex.m4 (gl_REGEX): Check for new glibc interface to
        translation table.

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

        * doc/gnulib-tool.texi (Modified imports): pathname -> file name.

2006-03-29  Mark D. Baushke  <mdb@gnu.org>
            Bruno Haible  <bruno@clisp.org>

        * lib/stdint_.h: On OpenBSD, don't redefine types already included in
        <sys/types.h> and <inttypes.h>.

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>

        * lib/base64.c: Fix problems reported by Eric Blake <ebb9@byu.net>,
        including some doc fixes.

2006-03-24  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * lib/base64.c (base64_encode): Do not read past end of array with

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,

2006-03-08  Simon Josefsson  <jas@extundo.com>

        * 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

        LIBREADLINE and LTLIBREADLINE outside the COMMANDS-TO-SET-IT.
        From Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

2006-03-07  Simon Josefsson  <jas@extundo.com>

        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>

        to be sync'd from gettext.
        * lib/mkdtemp.c, setenv.c, unsetenv.c: *Un*-normalize inclusion

2006-02-24  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/glob.c: Say "invalid" rather than "illegal" in comments.

        gl_CHDIR_SAFER.

2006-02-22  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.
        * m4/chdir-safer.m4: New file.

        AT_FDCWD exceeds INT_MAX.
        * lib/openat.h (AT_FDCWD): Likewise.

2006-02-17  Eric Blake  <address@hidden>

2006-02-16  Simon Josefsson  <jas@extundo.com>

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

2006-02-15  Simon Josefsson  <jas@extundo.com>

        * build-aux/maint.mk: Add dsyntax-check rule.

2006-02-15  Eric Blake  <ebb9@byu.net>

        * m4/sys_socket_h.m4 (gl_HEADER_SYS_SOCKET): Don't attempt using
        winsock2.h or ws2tcpip.h when sys/socket.h is present. Fixes
        'present but cannot compile' warnings on cygwin.
        * m4/socklen.m4 (gl_TYPE_SOCKLEN_T): Use gl_HEADER_SYS_SOCKET.  Don't
        use ws2tcpip.h if sys/socket.h works.
        * 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
        Bruno.

2006-01-24  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (argp-namefrob.h): sync lost.

2006-01-24  Jim Meyering  <jim@meyering.net>

        From Mark D. Baushke.

2006-01-24  Jim Meyering  <jim@meyering.net>

        * m4/openat.m4 (gl_FUNC_OPENAT): Add AC_LIBSOURCES([intprops.h]).
        Reported by Mark D. Baushke.

2006-01-24  Jim Meyering  <jim@meyering.net>

        * lib/socket_.h: Remove useless parentheses in uses of cpp `defined'.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * modules/strnlen (Maintainer): Change from glibc to all.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * m4/stdbool.m4 (AC_HEADER_STDBOOL): Check for IBM and HP-UX bugs.
        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
        expressions inside backquote.
        Report and solution by Mark D. Baushke <mdb@gnu.org>.

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.
        (getenv): Declare only if defined HAVE_DECL_GETENV &&
        !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>

        * m4/getopt.m4 (gl_PREREQ_GETOPT): Check for getenv decl.

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>.

2006-01-22  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/quotearg.c (quotearg_buffer_restyled): Add "default: break;"
        to pacify gcc -Wswitch-default.

2006-01-22  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (VASNPRINTF): In the computation of the size of the
        temporary buffer for sprintf, take into account the precision also
        for 'd', 'i', 'u', 'o', 'x', 'X'.

2006-01-21  Sergey Poznyakoff  <gray@gnu.org.ua>

        * modules/argp-tests: New module

        * lib/argp-namefrob.h (__argp_basename): Removed definition. Was a
        typo.
        (__argp_base_name): Provide macro definition or extern declaration
        depending on the configuration

2006-01-20  Simon Josefsson  <jas@extundo.com>

        * modules/inet_ntop (Depends-on): Depend on sys_socket.

2006-01-20  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Use -Wl,-z,ignore
        rather than -Xlinker -z -Xlinker ignore, as it's more portable.
        Suggested by Bruno Haible.

2006-01-20  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (argp-fmtstream.h, localcharset.c): comment out
        until changes propagate, I guess.

2006-01-19  Simon Josefsson  <jas@extundo.com>

        modules/md5-tests, modules/readline, modules/rijndael-tests: Use

        test_*_SOURCES.

2006-01-18  Simon Josefsson  <jas@extundo.com>

        * modules/socklen (Depends-on): Depend on sys_socket.

        it's not portable and it doesn't work with cross-compiles.
        Problem reported by Bruno Haible.  Fix missing-$ typo in

        Fall back on chown if open failed with EACCES.

        * lib/gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:

        (dev_from_mount_options)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:

        on Linux (since it doesn't).  It also parses "dev=" more carefully.
        (read_file_system_list)

        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.

        (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'.

        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'.

        * modules/regex (Depends-on): Add strcase.

        function.
        * modules/poll (License): Change from GPL to LGPL, since it's

        * lib/utimens.c (ENOSYS): Define if not already defined.

        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,

        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.

        module's job.
        * m4/jm-macros.m4 (gl_MACROS): Likewise.

2005-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.

        * lib/.cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h,
        stat-time.h.
        * lib/argmatch.h: Include verify.h
        (ARGMATCH_VERIFY): Use verify rather than rolling our own.
        (ARGMATCH_ASSERT): Remove; unused.
        * lib/canonicalize.c: Assume STDC_HEADERS.
        * lib/exclude.c: Include "strcase.h".
        * lib/regex_internal.h [!defined _LIBC]: Likewise.
        * lib/getusershell.c: Include stdio--.h rather than stdio.h
        and stdio-safer.h.
        (getusershell): Call fopen, not fopen_safer.
        * lib/save-cwd.c: Include fcntl--.h rather than fcntl.h.
        Do not include unistd-safer.h.
        (save_cwd): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * lib/getdate.y (relative_time): New type.
        (RELATIVE_TIME_0): New constant.
        (parser_control): Use relative_time instead of doing it ourselves.
        (%union): Add new relative_time rel member.
        (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):
        Now typeless.
        (relunit, relunit_snumber): Now of type rel.
        (zone, rel, relunit, get_date): Adjust to above changes.

        * lib/getloadavg.c: Include fcntl--.h rather than fcntl.h.
        Do not include unistd-safer.h.
        (getloadavg): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * lib/mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
        (make_dir_parents): Treat ENOSYS like EEXIST.

        Improve quality of diagnostics on restore_cwd failure.
        * lib/mkdir-p.h (make_dir): Remove.  All uses replaced by mkdir.
        (make_dir_parents): Last arg is now int * (for errno), not bool *.
        * lib/mkdir-p.c (make_dir, make_dir_parents): Likewise.
        Rewrite "mkdir -p" algorithm to avoid the need for "stat"
        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.

        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.

        * lib/getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin.
        [__linux__]: Allocate a big enough buffer for /proc/loadavg.
        [!LDAV_DONE]: Avoid unused variable warning.

        * gnulib-tool: Remove trailing slashes from the values specified for

        Suggested by Simon Josefsson <jas@extundo.com>.

        * 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>

2005-09-18  Bruno Haible  <bruno@clisp.org>

2005-09-16  Paul Eggert  <eggert@cs.ucla.edu>

        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.

        * 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.

        Check for arithmetic overflow when calculating sizes, to prevent

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.
        (regoff_t) [defined _REGEX_LARGE_OFFSETS]: Define to off_t, not int.
        (__re_idx_t, __re_size_t, __re_long_size_t): New types.

        New macros.

        Use the new types and macros to port to 64-bit hosts.
        Use unsigned types for internal values, so that the code
        mostly works even for arrays larger than SSIZE_MAX.

        * lib/regcomp.c (re_compile_fastmap_iter, init_dfa, init_word_char):
        (optimize_subexps, lower_subexp):
        Don't assume 1<<31 has defined behavior on hosts with 32-bit int,
        since the signed shift might overflow.  Use 1u<<31 instead.

        Remove no-longer-needed test for table_size > 0.
        * lib/regcomp.c (parse_sub_exp): Do not shift more bits than there are
        in a word, as the resulting behavior is undefined.
        * lib/regexec.c (check_dst_limits_calc_pos_1): Likewise;
        in one case, a <= should have been an <, and in another case the

        _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

        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.

        * 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.

        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>

        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):

        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_FIXED): Renamed from REGS_FIXED.

        (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values

        #undef these macros selectively.

        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_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.
        The old names are still supported if !_REGEX_SOURCE.
        The new names are always supported, regardless of _REGEX_SOURCE.
        (re_buffer): Renamed from buffer.
        (re_allocated): Renamed from allocated.

        (re_newline_anchor): Renamed from newline_anchor.

        Change the following member names in struct re_registers.
        The old names are still supported if !_REGEX_SOURCE.

2005-08-24  Bruno Haible  <bruno@clisp.org>

        * 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.

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>

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):

        [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.
        Add glibc bug 1217 for regcomp.c.

2005-08-19  Jim Meyering  <jim@meyering.net>

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.

        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.
        * lib/strstr.c: Completely rewritten, with multibyte locale support.

        * lib/strcasestr.h: New file.
        * lib/strcasestr.c: New file.

        wins.

        * lib/strftime.c (my_strftime)
        [! defined _LIBC && ! HAVE_RUN_TZSET_TEST]:
        Copy the input structure, to work around some of the bug with
        Solaris 2.5.1 and Solaris 2.6.  If you still care about these old
        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.

        * lib/base64.c (base64_encode): Indent.  Rename 'b64' to avoid
        collision with global variable.  Better indentation.  Don't
        increment buffer pointer beyond buffer end.  Based on comments

2005-06-28  Jim Meyering  <jim@meyering.net>

        * 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

        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.

2005-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/fts.m4 (gl_FUNC_FTS_CORE): Renamed from gl_FUNC_FTS.
        (gl_FUNC_FTS, gl_FUNC_FTS_LGPL): New macros.

2005-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * MODULES.html.sh (File system functions): Add fts, fts-lgpl.

2005-05-20  Jim Meyering  <jim@meyering.net>

        * lib/unlinkdir.h (cannot_unlink_dir) [UNLINK_CANNOT_UNLINK_DIR]:
        Now a macro, to pacify GCC.

2005-05-20  Eric Blake  <ebb9@byu.net>  (tiny change)

        * m4/chown.m4 (gl_FUNC_CHOWN): Correct sense of test for honoring IDs
        of -1.

2005-05-20  Eric Blake  <ebb9@byu.net>  (tiny change)

        * lib/chown.c (rpl_chown): Return -1 on failure.

2005-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/canonicalize.m4 (AC_FUNC_CANONICALIZE_FILE_NAME]):
        Don't check for stddef.h.
        * m4/fts.m4 (gl_FUNC_FTS): Don't require AC_HEADER_STDC, as we
        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.

2005-05-18  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/canonicalize.c: Include canonicalize.h first, to test interface.
        Include <stddef.h> unconditionally, since we assume C89 now.
        All uses of PTR_INT_TYPE replaced by ptrdiff_t.
        * lib/fts.c: Include fts_.h first, to check interface.
        Do not include intprops.h; no longer needed.
        Include cycle-check.h and hash.h, since fts_.h no longer does.
        Remove unnecessary casts of closedir to void.
        (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>

        * modules/dirfd (License): Change to LGPL.  Most of the code
        is already in the public domain.

2005-05-18  Jim Meyering  <jim@meyering.net>

        * m4/fts.m4 (AC_LIBSOURCES): Add intprops.h to the list.
        Reported by Yoann Vandoorselaere.

2005-05-17  Jim Meyering  <jim@meyering.net>

        * m4/fts.m4: New file, from coreutils.

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.

2005-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * 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,

        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

        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>

        (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

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>

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):

        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.

        (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
        at the correct time.  Simplify calculation of "+u" and its ilk.
        Don't mishandle "+X".
        (mode_free): Remove "register" and localize decls.
        * lib/modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        (struct mode_change): Move to modechange.c; callers don't
        need to see this stuff.
        (MODE_MASK_EQUALS, MODE_MASK_PLUS, MODE_MASK_MINUS, MODE_MASK_ALL):
        (MODE_INVALID, MODE_MEMORY_EXHAUSTED, MODE_BAD_REFERENCE): Remove.
        (mode_change, mode_adjust): Reflect the new signatures noted above.
        * lib/nanosleep.c (rpl_nanosleep): Include "timespec.h" before macros
        that might redefine system include files.
        (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro.
        (my_usleep): Use NULL rather than (void *) 0.
        (rpl_nanosleep) [!defined SA_NOCLDSTOP]:
        Use siginterrupt to specify that system calls should be interrupted.
        (rpl_nanosleep): Move initialization of suspended closer to call of
        my_usleep.
        * lib/readutmp.h (read_utmp): New arg OPTIONS.  All uses changed.
        * lib/readutmp.c: Likewise.  Include signal.h, stdbool.h.
        (desirable_utmp_entry): New function.
        (read_utmp) [defined UTMP_NAME_FUNCTION]: Redo memory allocation
        using x2nrealloc, to simplify logic.
        (read_utmp) [!defined UTMP_NAME_FUNCTION]: Check for overflow in
        size calculation.  Do not assume utmp file is a regular file.
        * lib/readutmp.h (UT_PID): Moved here from ../src/who.c.
        (READ_UTMP_CHECK_PIDS): New constant.
        * lib/save-cwd.c: Include unistd-safer.h.
        (save_cwd): Use fd_safer.
        * lib/tempname.c (S_ISDIR, S_IRUSR, S_IRUSR, S_IWUSR, S_IXUSR): Remove.
        [!_LIBC] Include "stat-macros.h" instead.
        * lib/unistd-safer.h (fd_safer): New decl.

        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
        HAVE_LONGLONG_64BIT.

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.
        * config/config.rpath: update.

2005-03-15  Bruno Haible  <bruno@clisp.org>

        * lib/regex.c (byte_re_match_2_internal): Rename local variable 'not'
        to 'negate'.

        * lib/regex.c (byte_re_match_2_internal): Reduce scope of same_str_p
        variable.

        * lib/regex.c (EXTEND_BUFFER, regcomp): Cast the realloc/malloc
        results.

2005-03-14  Simon Josefsson  <jas@extundo.com>

        * lib/timegm.h: Use proper prototype CPP guards, reported by Dave Love
        <fx@gnu.org>.

2005-03-14  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,
        TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from
        intprops.h.
        * lib/strtol.c: Likewise.

2005-03-14  Jim Meyering  <jim@meyering.net>

        * lib/strftime.c (my_strftime) [HAVE_STRFTIME && ! (_NL_CURRENT
        && HAVE_STRUCT_ERA_ENTRY)]: Initialize the first byte of ubuf[]
        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:
        Update from GNU gettext 0.14.3.

2005-03-10  Jim Meyering  <jim@meyering.net>

        * m4/save-cwd.m4 (gl_SAVE_CWD): Check for fchdir.

2005-03-10  Jim Meyering  <jim@meyering.net>

        * lib/save-cwd.c [!HAVE_FCHDIR]: Define open, fchdir, and chdir_long
        so that this module works on systems without fchdir.

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.
        * lib/sig2str.h: Include <signal.h>, intprops.h.
        (INT_STRLEN_BOUND): Remove.
        * lib/strftime.c (TYPE_SIGNED): Remove.
        (INT_STRLEN_BOUND): Switch to same implementation as intprops.h.
        * lib/strtol.c: Adjust comments to match intprops.h.
        * 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>

        * m4/mmap-anon.m4 (MAP_FILE, MAP_FAILED): Remove definitions.

2005-03-07  Bruno Haible  <bruno@clisp.org>

        * lib/pagealign_alloc.c (MAP_FILE, MAP_FAILED): Define fallbacks.

2005-03-04  Derek R. Price  <derek@ximbiot.com>

        * gnulib-tool (func_cp_if_changed, func_mv_if_changed): New functions.
        (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  Derek R. Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * modules/pagealign_alloc: New file.
        * MODULES.html.sh (Memory management functions): Add pagealign_alloc.

2005-03-03  Derek R. Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * lib/pagealign_alloc.h: New file.
        * lib/pagealign_alloc.c: 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.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/xnanosleep.m4 (gl_XNANOSLEEP): Remove configuration attempting
        to detect nanosleep bug.

2005-03-01  Bruno Haible  <bruno@clisp.org>

        * lib/vasnprintf.c (EOVERFLOW): Define to a fallback if needed.

2005-02-26  Paul Eggert  <eggert@cs.ucla.edu>

        * modules/gethrxtime: New file.
        * modules/xnanosleep (Files): Add m4/xnanosleep.m4.
        (Depends-on): Add gethrxtime.
        (configure.ac): Add gl_XNANOSLEEP.
        (Makefile.am): Remove lib_SOURCES line.

2005-02-25  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/gethrxtime.m4, m4/xnanosleep.m4: New files.
        * m4/gettime.m4 (gl_GETTIME): Check for nanotime.

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>

        * lib/config.charset: Update from GNU gettext 0.14.2.

2005-02-24  Bruno Haible  <bruno@clisp.org>

2005-02-22  Jim Meyering  <jim@meyering.net>

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Fix typo:
        s/ifndef/ifdef/.

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
        dereference state.root_argp.

        (ME_DUMMY): Count "subfs" as a dummy.  Problem reported by
        Dmitry V. Levin.
        Include mountlist.h first, to test the interface.

        * modules/chdir-long (Depends-on): Remove mempcpy.

2005-01-21  Jim Meyering  <jim@meyering.net>

        * lib/openat.h (AT_SYMLINK_NOFOLLOW): Define to 4096, so it's the
        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

        * lib/version-etc.c: Remove version_etc_copyright.
        * lib/version-etc.h (version_etc_copyright): Use [] instead of * in
        prototype, suggested by Paul Eggert <eggert@CS.UCLA.EDU>.

2005-01-20  Simon Josefsson  <jas@extundo.com>

        * lib/base64.h (isbase64): Add.

        * lib/base64.c (isb64): Rename to isbase64, use to_uchar instead of

2005-01-20  Paul Eggert  <eggert@cs.ucla.edu>

        * m4/save-cwd.m4 (gl_SAVE_CWD): Remove check for fcntl; we now assume
        it.

2005-01-20  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/save-cwd.c (save_cwd): Remove code to support the case
        where fchdir is missing or flaky.

        AC_LIBSOURCES now does this.
        * MODULES.html.sh (Sizes of integer types <limits.h>): New element,
        with new ullong_max module.

2005-01-19  Bruno Haible  <bruno@clisp.org>

        * 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>

        * 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.

        * lib/stpncpy.c: Remove HAVE_STPNCPY and gnu_stpncpy renaming,

2005-01-17  Bruno Haible  <bruno@clisp.org>

        used.

2005-01-17  Bruno Haible  <bruno@clisp.org>

        * lib/fwriteerror.h (fwriteerror): Change specification to include
        fclose.

        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

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>

        * m4/getaddrinfo.m4: New file.

2004-11-10  Simon Josefsson  <jas@extundo.com>

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>.

2004-11-04  Bruno Haible  <bruno@clisp.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.

        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.

        Use NULL instead of 0 where appropriate.
        (to_hour): Avoid abort (), to avoid a dependency on
        stdlib.h.

        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,

        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.

            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>

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.

        (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
        compatible extension.  Simplify code by removing a boolean int
        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>

        (readtoken): Use `size_t' rather than int/long.
        All callers adjusted.
        Use `bool' rather than `int' where appropriate.
        Use memset rather than an explicit loop.
        Use x2nrealloc rather than xrealloc.
        Allow the use of `\0' as a delimiter.
        (readtokens): Likewise.
        * lib/readtokens.h (readtoken, readtokens): Update prototypes.

2004-03-30  Jim Meyering  <jim@meyering.net>

        * m4/realloc.m4: Remove file, since now it does no more than
        AC_REQUIRE([AC_FUNC_REALLOC]), and that can be done via
        the `configure.ac' section of module/realloc.
        * m4/malloc.m4: Likewise, but for AC_FUNC_MALLOC.

2004-03-30  Bruno Haible  <bruno@clisp.org>

2004-03-09  Paul Eggert  <eggert@twinsun.com>

        * m4/c-stack.m4 (gl_PREREQ_C_STACK): Renamed from jm_PREREQ_C_STACK.
        All uses changed.  Check for sa_sigaction member; this fixes
        a bug first reported by Jason Andrade in
        <http://mail.gnu.org/archive/html/bug-textutils/2003-03/msg00027.html>.

2004-03-07  Paul Eggert  <eggert@twinsun.com>

        * lib/c-stack.c (SIGACTION_WORKS): New macro.  Use it instead of long
        '#if' expressions.  Unlike the code it replaces, it does not
        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>.

        * lib/quotearg.c (quotearg_alloc): New function.
        (quotearg_buffer_restyled): Treat lone { and } as special.
        Treat = as special.  Work around bug with older shells
        that "see" a '\' that is really the 2nd byte of a multibyte char.
        Quote empty string with shell_quoting_style.

        volatile stack_base, volatile_stack_size): Remove.
        (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.

        * lib/mktime.c (__mktime_internal) [!_LIBC]: Define to mktime_internal
        so as not to conflict with a different-sized __mktime_internal
        function in GNU libc.

        gt_TYPE_SSIZE_T.

2003-11-24  Paul Eggert  <eggert@twinsun.com>

        * modules/alloca: Remove dependency on xalloc.

2003-11-24  Paul Eggert  <eggert@twinsun.com>

        * lib/alloca.c: Remove dependency on xalloc module.
        (xalloc_die): Remove.
        (memory_full) [!defined emacs]: New macro.
        [!defined emacs]: Don't include xalloc.h.
        (alloca): Invoke memory_full, not xalloc_die, if malloc fails or
        address arithmetic overflows.  Change datatypes a bit to avoid
        unnecessary casts.

2003-11-22  Jim Meyering  <jim@meyering.net>

        * lib/xmalloc.c (x2nrealloc_inline): Fix typos in comments:
        s/size/size_t/.

2003-11-21  Karl Berry  <karl@gnu.org>

        * config/config.{sub,guess}: update from config.

2003-11-18  Karl Berry  <karl@gnu.org>

        * config/config.{sub,guess}: update from config.

        * config/(printf-{parse,args}.[ch]): sync broken, sigh.

2003-11-17  Paul Eggert  <eggert@twinsun.com>

        * README: Mention that S+T cannot overflow if S is the size of
        an existing object and T is sufficiently small.

2003-11-17  Jim Meyering  <jim@meyering.net>

        On systems without utime and without a utimes function capable of
        dealing with a NULL struct utimbuf* argument, this utime replacement
        could -- in unusual circumstances -- leak a file descriptor.
        * lib/utime.c: Include <unistd.h> and <errno.h>.
        (utime_null): Be sure to close `fd' and to preserve errno.
        Reported by Geoff Collyer via Arnold Robbins.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * modules/vasnprintf (Files): Add m4/ssize_t.m4.
        (Depends-on): Add xsize.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * m4/vasnprintf.m4 (gl_PREREQ_PRINTF_PARSE): Require gt_TYPE_SSIZE_T.

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.

2003-10-15  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;

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.
        * lib/xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM,
        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.
        * lib/xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum
        value.
        (_STRTOL_ERROR): Handle it.  Abort when given unknown error codes.
        * lib/xstrtoul.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM): New macros.
        * lib/xstrtoumax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM)
        [defined UINTMAX_MAX]: New macros.

        * lib/xalloc.h (xnmalloc, xzalloc, xnrealloc, xclone): New decls.
        (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.

2003-10-08  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.
        (version_etc_va): New declaration.
        * lib/version-etc.c: Include stdarg.h, stdlib.h.
        (version_etc_copyright): Declare as readonly.
        (version_etc_va): New function. Provide a different translatable string
        for each possible number of authors < 10. Abbreviate when there are 10
        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.

        * 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

        * 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]:
        Disable cancellation while printing error.
        * 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>

2003-09-17  Paul Eggert  <eggert@twinsun.com>

        * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Call AC_BEFORE first,

2003-09-17  Paul Eggert  <eggert@twinsun.com>

        (tags_regexp): Remove, since \| doesn't conform to POSIX.
        (sed_extract_prog): Issue s commands one-by-one, rather than
        using \| in one s command.

2003-09-16  Paul Eggert  <eggert@twinsun.com>

        * lib/linebuffer.c (readlinebuffer): Return NULL immediately upon

        (__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.

        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.

        * 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>

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.

        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.

        fixing a typo.

        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.

        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.

        * 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.

        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.

        (memcasecmp): Don't assume size_t fits in unsigned int.
        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".
        (xmalloc, xrealloc): Remove decls.
        (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.
        (is_space): New fn.
        (add_exclude_file): If LINE_END is a space, ignore trailing spaces
        and empty lines.

        * lib/argp-help.c, argp-parse.c, config.charset, getopt.h:
        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>

        Merge from coreutils.

        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.
        * config/config.guess, config.sub, install-sh, missing, texinfo.tex:
        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,
        longdouble.m4, nls.m4, po.m4, progtest.m4, signed.m4, wchar_t.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.
        * m4/timespec.m4 (jm_CHECK_TYPE_STRUCT_TIMESPEC):
        Require gl_USE_SYSTEM_EXTENSIONS.
        * m4/unlocked-io.m4 (jm_FUNC_GLIBC_UNLOCKED_IO):
        Require gl_USE_SYSTEM_EXTENSIONS rather than AC_GNU_SOURCE.

2003-08-08  Paul Eggert  <eggert@twinsun.com>

        * MODULES.html.sh (func_all_modules): Add extensions, gnu-source.
        * modules/extensions, modules/gnu-source: New files.
        * modules/timespec, modules/unlocked-io: Depend on extensions.

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.

        * 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>.

2003-07-16  Karl Berry  <karl@gnu.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?

2003-07-16  Jim Meyering  <jim@meyering.net>

        * modules/save-cwd: Depend on xgetcwd.  From Derek Price.

2003-07-15  Paul Eggert  <eggert@twinsun.com>

        ref-del.sin.  From Bruno Haible.
        * config/srclist-update (fixfile): Change grep pattern again, since the

        '[$]' to escape the $s.

2003-07-15  Karl Berry  <karl@gnu.org>

        Switch from LGPL to GPL.

2003-07-14  Paul Eggert  <eggert@twinsun.com>

        * lib/asnprintf.c, asprintf.c, config.charset, gettext.h,

        printf-args.h, printf-parse.c, printf-parse.h, ref-add.sin,
        ref-del.sin, setenv.c, unsetenv.c, vasnprintf.c, vasnprintf.h,
        vasprintf.c, vasprintf.h: Regenerate.  These files are now being
        updated automatically by ../config/srclist-update.  This changes
        their license from LPGL to GPL.

2003-07-14  Paul Eggert  <eggert@twinsun.com>

        * config/srclist.txt: Add tons more gettext files.  $GETTEXT is now
        assumed to refer to the root of the most recent stable gettext version.
        * config/srclistvars.sh: Add defaults for eggert.
        * config/srclist-update: Convert LGPL to GPL in shell scripts, too.

2003-07-14  Jim Meyering  <jim@meyering.net>

        Don't emit diagnostics.  Let callers do that.
        * lib/save-cwd.c: Don't include "error.h".

        when returning nonzero.

        * lib/save-cwd.h (restore_cwd): Update prototype.
        * lib/save-cwd.c (restore_cwd): Remove two parameters.
        Simplify.  Don't call error upon failure.  Let callers do that.
        (save_cwd): Mention that Irix 5.3 has the same problem as SunOS 4
        when auditing is enabled.  But don't bother updating the #if.

2003-07-11  Alexandre Duret-Lutz  <adl@gnu.org>

        * lib/obstack.h (__INT_TO_PTR): Revert change of 2003-03-13;
        it breaks C++ compilation.
        [!__GNUC__ || !__STDC__] (obstack_finish): Cast result to void*.

2003-07-10  Simon Josefsson  <jas@extundo.com>

        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.

        * modules/localcharset: Likewise.

2003-06-07  Jim Meyering  <jim@meyering.net>

        * lib/readtokens.h: Put `Free Software Foundation, Inc.'
        in place of my name in the copyright comment.
        Remove definition and uses of __P.

        From coreutils.
        * lib/stat.c: Don't declare xmalloc explicitly.
        Instead, include "xalloc.h".
        * lib/readtokens.c (readtokens): Remove anachronistic casts of xmalloc,
        xrealloc, and xcalloc return values.
        * lib/xgetcwd.c (xgetcwd): Include "xgetcwd.h".
        Improve comment.
        * lib/xgetcwd.h: Remove definition/uses of PARAMS.

2003-06-07  Bruno Haible  <bruno@clisp.org>

        * modules/poll (Makefile.am): Use explicit creation rule for poll.h, to

2003-06-07  Bruno Haible  <bruno@clisp.org>

        * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH, gl_FUNC_FNMATCH_POSIX,
        gl_FUNC_FNMATCH_GNU): Set FNMATCH_H instead of invoking
        AC_CONFIG_LINKS. Needed to allow for a different name of the lib
        directory.
        * m4/poll.m4 (gl_FUNC_POLL): Set POLL_H instead of invoking
        AC_CONFIG_LINKS. Needed to allow for a different name of the lib
        directory.

2003-06-06  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * lib/same.c: (same_name): Declare *_basename locals to be `const'.
        Consolidate declarations and initializations of *_base* locals.

        Merge from coreutils.
        This avoids a core dump on systems without GNU putenv,
        when running `env -u SOME_ALREADY_UNSET_VARIABLE'.
        * lib/putenv.c (__set_errno, LOCK, UNLOCK): Define.
        (unsetenv): New static function, from GNU libc.
        (rpl_putenv): Use it.

        * lib/modechange.c: Remove trailing blanks.

        Merge from coreutils.
        * 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.

        * lib/quote.c: Dont include <stddef.h> or <sys/types.h>; not needed.

        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.

2003-05-18  Karl Berry  <karl@gnu.org>

        * config/srclistvars.sh (TEXMF): use TEXMFROOT instead, since TEXMF
        might actually be set by the user.

2003-05-17  Bruno Haible  <bruno@clisp.org>

        From GNU libc.
        * lib/strftime.c (my_strftime): Handle very large width

        * lib/exclude.h (PARAMS): Remove definition and uses.
        * lib/exclude.c: Remove uses of `PARAMS'.

        * lib/dirname.c [TEST_DIRNAME]: Update build instructions for test.
        Add test-cases for DOS filenames. Declare program_name.

        * lib/mountlist.c (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any

        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

        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'.

        Merge in changes from libc's misc/error.c, in preparation
        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.
        Include unlocked-io.h only if !_LIBC.

        (free) [defined emacs && defined EMACS_FREE]: Define to EMACS_FREE.

        (alloca): Use old-style definition, since Emacs needs this.
        Check for arithmetic overflow when computing combined size.

2002-12-04  Paul Eggert  <eggert@twinsun.com>

        Do not generate unlocked-io.h automatically, since it's easier to
        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/Makefile.am: Add copyright notice.
        (libfetish_a_SOURCES): Add unlocked-io.h.

        * 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/xstat.in [@BEGIN_LSTAT_ONLY@]: Include <string.h>.

        * lib/fsusage.c: Remove unneeded parentheses around operands of
        `defined'.

2002-11-22  Paul Eggert  <eggert@twinsun.com>

        * 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.
        Similarly, assume HAVE_C_BACKSLASH_A, CHAR_BIT, UCHAR_MAX, UINT_MAX,
        HAVE_STDLIB_H, HAVE_STRING_H, STDC_HEADERS.

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.

        warning on FreeBSD.

        (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>

        Remove case insensitive option matching.

2002-11-20  Paul Eggert  <eggert@twinsun.com>

        Merge argmatch cleanups from Bison.  Assume C89.

        * 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.
        (ARRAY_CARDINALITY, ARGMATCH, ARGCASEMATCH, invalid_arg,

2002-09-28  Karl Berry  <karl@gnu.org>

        * 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.

        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.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        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>

        * lib/readutmp.h (UT_TYPE): Remove definition (now in who.c).
        (HAVE_STRUCT_XTMP_UT_EXIT, HAVE_STRUCT_XTMP_UT_ID): Define.
        (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/acl.m4: New file.
        * 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.

2001-12-15  Jim Meyering  <meyering@lucent.com>

        * lib/regex.h (__restrict_arr): Update from libc.

        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <akim@epita.fr>

        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

        a warning about an integer-to-pointer conversion problem with getenv.
        Reported by Volker Borchert.

2001-11-26  Jim Meyering  <meyering@lucent.com>

2001-11-19  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
        limit.

        * 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

        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

        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.

        (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.

2001-10-21  Jim Meyering  <meyering@lucent.com>

        * lib/obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,

        * lib/regex.c (_): Likewise.

        * m4/error.m4 (jm_PREREQ_ERROR):

        (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.

2001-10-11  Jim Meyering  <meyering@lucent.com>

        * lib/argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...

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.

2001-09-29  Paul Eggert  <eggert@twinsun.com>

        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/.

        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.

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
        #defines strtoimax.  Also treat the other strto* functions
        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.

        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>

        * lib/gettimeofday.c (rpl_gettimeofday): Declare local variable
        `result'.

        * 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.
        (MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when
        the deprecated MOUNTED symbol is no longer defined in mntent.h.

2001-09-22  Jim Meyering  <meyering@lucent.com>

        * m4/gettext.m4: New file.  From gettext.
        * m4/lcmessage.m4: Sync with gettext -- this changes only comments.
        * m4/progtest.m4: Likewise
        * m4/isc-posix.m4: Decrement serial number to sync with gettext.
        * m4/glibc21.m4: Likewise.

        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.

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.

2001-09-11  Jim Meyering  <meyering@lucent.com>

        * m4/host-os.m4 (UTILS_HOST_OS): 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.

2001-09-01  Jim Meyering  <meyering@lucent.com>

        * 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.

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.

        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.

        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

        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

        * 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.

        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.

2001-05-20  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>

        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/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.

2001-03-20  Bruno Haible  <haible@clisp.cons.org>

        * m4/iconv.m4 (jm_ICONV): Recommend GNU libiconv.

2001-03-19  Paul Eggert  <eggert@twinsun.com>

        * lib/version-etc.c (version_etc_copyright): Update to 2001.

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.

        * 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.

2001-02-25  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/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>

        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>

        * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Check for stddef.h, now that
        quotearg.c includes it.

2001-01-26  Jim Meyering  <meyering@lucent.com>

        * lib/quotearg.c: Include stddef.h.
        * lib/quote.c: Include stddef.h.
        Reported by Axel Kittenberger.

        * lib/xmalloc.c [HAVE_DONE_WORKING_MALLOC_CHECK]: Enclose error-evoking
        line in double quotes so that it evokes a better diagnostic.
        [HAVE_DONE_WORKING_REALLOC_CHECK]: Likewise.
        Reported by Axel Kittenberger.

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'.

2001-01-21  Bruno Haible  <haible@clisp.cons.org>

        * m4/iconv.m4 (jm_ICONV): Also check whether the iconv declaration
        has const.

2001-01-21  Bruno Haible  <haible@clisp.cons.org>

        * lib/unicodeio.c (print_unicode_char): Cast the second iconv() arg,
        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,
        for autoconf-2.49c.
        * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Likewise.

2001-01-16  Jim Meyering  <meyering@lucent.com>

        * lib/basename.c: Include <stdio.h>, needed by assert on SunOS 4.
        From Bruno Haible.

2001-01-14  Jim Meyering  <meyering@lucent.com>

        * m4/rename.m4: Use temporary directories named conftestdir{,2}, not
        foo and bar.  Create conftestdir/ in the script, not in the C code.
        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.

2001-01-14  Jim Meyering  <meyering@lucent.com>

        * 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.

2001-01-03  Jim Meyering  <meyering@lucent.com>

        * lib/unicodeio.c (print_unicode_char): Remove `const' from declaration
        of local `inptr' to avoid warning with some system declarations of
        iconv.

2001-01-02  Volker Borchert  <bt@teknon.de>

        * m4/rename.m4: New file.

        * 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.
        (_jm_DECL_HEADERS): Check for grp.h and pwd.h.
        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.
        (S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR,
         S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH):
        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.
        (hash_get_first): Return NULL to appease Irix5.6's 89.

        * m4/jm-macros.m4 (jm_MACROS): Require jm_AC_DOS.

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
        SHELLS_FILE to a file name that's useful on djgpp systems.

        (default_shells): Prepend ADDITIONAL_DEFAULT_SHELLS.
        Based mostly on a patch from Prashant TR.

2000-12-16  Bruno Haible  <haible@clisp.cons.org>

        * lib/config.charset: Add ISO-8859-3, BIG5HKSCS, GB18030, JOHAB,
        VISCII, CP874, CP949, CP950, CP1250, CP1253, CP1254, CP1255, CP1256,
        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>

        * lib/stripslash.c (ISSLASH): Define.
        (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.
        (dir_name): Append `.' if necessary.
        Based mostly on patches from Prashant TR and Eli Zaretskii.

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/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.

        * 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>

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.

        * regex.c (re_iswctype, re_wctype_to_bit): Fix braino.

        (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>

        * 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.
        [!weak_alias]: Define __memchr to memchr.

        * lib/regex.h: Likewise.
        * lib/getopt1.c: Likewise.
        * lib/memcmp.c: Likewise.

        * lib/getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.

        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):
        Giving in to popular pressure to shut up the compiler with casts.

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.
        * m4/prereq.m4 (jm_PREREQ_DIRNAME): New macro.
        * m4/jm-macros.m4 (AC_REPLACE_FUNCS): Add memrchr.

2000-10-21  Jim Meyering  <meyering@lucent.com>

        * 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.
        Guard weak_alias use with `#ifdef weak_alias'.

2000-10-21  Jim Meyering  <meyering@lucent.com>

        * lib/dirname.c (dir_name_r): New function, factored out of dir_name.
        (dir_name): Use dir_name_r.
        * lib/dirname.h (dir_name_r): Declare it.

2000-10-17  Jim Meyering  <meyering@lucent.com>

        * lib/quote.h (PARAMS): Define and use.
        Reported by Akim Demaille.

        * lib/getopt.c: Update from libc.

2000-10-16  Jim Meyering  <meyering@lucent.com>

        * lib/hard-locale.c (hard_locale): Use "", not 0 as 2nd arg to
        setlocale.
        From Jan Fedak.

2000-10-15  Stefan Monnier  <monnier@cs.yale.edu>

        * regex.c (WIDE_CHAR_SUPPORT): Define if _LIBC as well.

2000-09-25  Jim Meyering  <meyering@lucent.com>

        * lib/md5.h (rol): Define (from GnuPG).

        * lib/sha.c: Give credit (GnuPG) where due.
        (M): Use rol rather than open-coding it.
        Add a FIXME comment.

2000-09-21  Jim Meyering  <meyering@lucent.com>

        * lib/userspec.c (parse_user_spec): Remove debugging printf I'd added.
        Reported by Michael Stone.

2000-09-20  Jim Meyering  <meyering@lucent.com>

        * lib/Makefile.am (libfetish_a_SOURCES): Add sha.c.
        (noinst_HEADERS): Add sha.h.
        Based on code from Scott G. Miller and from GnuPG.

2000-09-18  Jim Meyering  <meyering@lucent.com>

        * m4/getloadavg.m4 (AC_FUNC_GETLOADAVG): Restore the initial value of
        LIBS. Otherwise, everyone ends up linking with -lelf for some
        configurations.
        Reported by Mike Stone.

2000-09-15  Jim Meyering  <meyering@lucent.com>

        * lib/regex.c: Update from libc.

2000-09-10  Jim Meyering  <meyering@lucent.com>

        * lib/getopt.c (_getopt_internal): Update from glibc.

2000-09-09  Jim Meyering  <meyering@lucent.com>

        * lib/quotearg.c: Rename ISASCII to IN_CTYPE_DOMAIN, so people don't
        think it should be used as a general replacement for isascii.
        * lib/fnmatch.c: Likewise.
        * lib/mbswidth.c: Likewise
        * lib/regex.c: Likewise.

        Don't use atoi.
        * lib/userspec.c: Include sys/param.h and limits.h.
        Include xstrtol.h.
        (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Define.
        (UID_T_MAX, GID_T_MAX, MAXUID, MAXGID): Define.
        (parse_user_spec): Use xstrtoul, not atoi when converting numeric
        UID, GID.  Check range.

2000-09-06  Jim Meyering  <meyering@lucent.com>

        * lib/getopt.c (_getopt_internal): Update from glibc.

2000-08-30  Jim Meyering  <meyering@lucent.com>

        * lib/strftime.c: Merge in changes from GNU libc.

        * m4/jm-macros.m4: Use jm_FUNC_FPENDING.
        * m4/fpending.m4: New file.

2000-08-26  Jim Meyering  <meyering@lucent.com>

        * lib/closeout.c: Include "__fpending.h".
        (close_stdout_status): Return right away if there's nothing to flush.

        * lib/Makefile.am (noinst_HEADERS): Add __fpending.h.
        * lib/__fpending.c: New file.
        * lib/__fpending.h: New file.

2000-08-20  Jim Meyering  <meyering@lucent.com>

        * 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>

        Improve fileutils installation on systems where running
        programs (like install) can't be unlinked.
        * m4/unlink-busy.m4 (jm_FUNC_UNLINK_BUSY_TEXT): New file/macro.
        * m4/jm-macros.m4: Use jm_FUNC_UNLINK_BUSY_TEXT.

2000-08-07  Paul Eggert  <eggert@twinsun.com>

        Standardize on "memory exhausted" instead of "Memory exhausted"
        or "virtual memory exhausted".
        * lib/obstack.c (print_and_abort): Use "memory exhausted", not
        "virtual memory exhausted".
        * lib/same.c (same_name): Invoke xalloc_die instead of printing
        our own message.
        * lib/userspec.c (parse_user_spec): Likewise.
        * lib/bumpalloc.h: comment fix
        * lib/same.c, userspec.c: Include xalloc.h.

        * lib/xalloc.h (xalloc_msg_memory_exhausted): Now char const[],
        not char *const and pointing to a constant array.
        * lib/xmalloc.c (xalloc_msg_memory_exhausted): Likewise.
        (xrealloc): Comment fix.

        * lib/userspec.c (parse_user_spec):
        Don't translate a message until just before returning,
        to avoid unnecessary translation.

2000-08-06  Paul Eggert  <eggert@twinsun.com>

        * m4/mbstate_t.m4 (AC_MBSTATE_T): Define mbstate_t to be int,
        not char, for compatibility with glibc 2.1.3 strftime.c.

2000-08-03  Greg McGary  <greg@mcgary.org>

        * lib/regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER,
        ELSE_EXTEND_BUFFER_HIGH_BOUND): New macros.
        (EXTEND_BUFFER): Use them.

2000-08-01  Jim Meyering  <meyering@lucent.com>

        * lib/dirname.c (ISSLASH): Define.
        (BACKSLASH_IS_PATH_SEPARATOR): Define.
        (dir_name) [BACKSLASH_IS_PATH_SEPARATOR]: Handle the case in which
        both `\' and `/' may be use as path separators.
        Based on a patch from Prashant TR.

2000-07-31  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (quotearg_n_options): Don't make the initial
        slot vector a constant, since it might get modified.

2000-07-31  Jim Meyering  <meyering@lucent.com>

        * lib/xmalloc.c: Use `virtual memory exhausted', not
        `Memory exhausted'.
        * lib/obstack.c (print_and_abort): Likewise.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c (quotearg_n_options): Preallocate a slot 0
        buffer, so that the caller can always quote one small
        component of a "memory exhausted" message in slot 0.
        From a suggestion by Jim Meyering.

2000-07-30  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.c (make_path): Quote the other instance, too.

        * lib/quotearg.c (N_STATIC_SLOTVECS): Define.
        (STATIC_BUF_SIZE): Define.
        (quotearg_n_options): Use only statically allocated storage when
        N < N_STATIC_SLOTVECS and the length of the quoted result is smaller
        than STATIC_BUF_SIZE.

2000-07-29  Jim Meyering  <meyering@lucent.com>

        * lib/basename.c (base_name): Use ISSLASH rather than comparing against
        `/'.

2000-07-29  Bruno Haible  <haible@clisp.cons.org>

        (mbswidth): New declaration.
        (MBSW_ACCEPT_INVALID, MBSW_ACCEPT_UNPRINTABLE): New macros.
        * lib/mbswidth.c (mbswidth): Add a flags argument.
        (mbsnwidth): New function.

2000-07-24  Jim Meyering  <meyering@lucent.com>

        * lib/mbswidth.c: Remove useless #else.  From Bruno Haible.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Check for wcwidth declaration.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * lib/quotearg.c: Streamline by invoking multibyte code only if needed.
        <wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX.
        (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX).
        (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):

        (wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.

2000-07-23  Jim Meyering  <meyering@lucent.com>

        * m4/check-decl.m4 (jm_CHECK_DECLS): Check for declarations of these,
        too: getgrgid, getpwuid, getuid.

2000-07-23  Jim Meyering  <meyering@lucent.com>

        * lib/basename.c (base_name): Add an assertion.

2000-07-23  Bruno Haible  <haible@clisp.cons.org>

        * lib/quotearg.c: When the system forces us to redefine mbstate_t,
        shadow its mbsinit function.

2000-07-17  Bruno Haible  <haible@clisp.cons.org>

        * lib/mbswidth.h: New file.
        * lib/mbswidth.c: New file.
        * lib/Makefile.am (libfetish_a_SOURCES): Add mbswidth.c.
        (noinst_HEADERS): Add mbswidth.h.

2000-07-17  Bruno Haible  <haible@clisp.cons.org>

2000-07-15  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.c: Include quote.h.

        corresponding argument in a `quote (...)' call.
        Give better diagnostics.

        * lib/Makefile.am (libfetish_a_SOURCES): Add quote.c.
        (noinst_HEADERS): Add quote.h.

        * lib/quote.c (quote, quote_n): New file.  Two functions taken verbatim
        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.

2000-07-14  Jim Meyering  <meyering@lucent.com>

        * lib/quotearg.h (enum quoting style): New enum clocale_quoting_style.

        * 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
        to link seq.  If so, set SEQ_LIBM to -lm.  From Bruno Haible.

        * m4/gnu-source.m4 (AC__GNU_SOURCE): New file/macro.
        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require it.

2000-07-09  Jim Meyering  <meyering@lucent.com>

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>
        and Bruno Haible  <haible@clisp.cons.org>

        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.

        * 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.
        Add AC_CHECK_HEADERS(stdlib.h), since we use HAVE_STDLIB_H.

        * lib/readutmp.h: [HAVE_UTMPX_H]: Include <utmp.h> if HAVE_UTMP_H.
        This is necessary to get a definition of e.g., UTMP_FILE on
        HP-UX 10.20.
        From Bob Proulx.

2000-07-02  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>

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>

        * 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/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.

2000-06-14  Paul Eggert  <eggert@twinsun.com>

        * lib/getdate.y (get_date): Apply relative times after time
        zone indicator, not before.  Reported by Todd A. Jacobs.

        * lib/Makefile.am (all-local): Depend on lstat.c and stat.c.

        * 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.

2000-06-03  Jim Meyering  <meyering@lucent.com>

2000-05-24  Jim Meyering  <meyering@lucent.com>

        * m4/prereq.m4: Use []-quoted list in AC_CHECK_MEMBERS, now that
        autoconf requires that.

2000-05-18  Jim Meyering  <meyering@lucent.com>

        (hash_delete): Rewrite to use neither the assignment operator
        nor the comma operator in an if-expression.

2000-05-15  Paul Eggert  <eggert@twinsun.com>

        * lib/closeout.c:
        <sys/stat.h>, <sys/types.h>, <unistd.h>, (STDOUT_FILENO):
        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>

        * lib/version-etc.c (version_etc_copyright): Update the copyright
        string used in all --version output.

        * m4/largefile.m4 (AC_SYS_LARGEFILE): Define _XOPEN_SOURCE to
        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.

2000-05-06  Jim Meyering  <meyering@lucent.com>

        * m4/jm-macros.m4 (AC_REPLACE_FUNCS): Add atexit.

        * 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

        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.

2000-04-25  Jim Meyering  <meyering@lucent.com>

        * lib/makepath.c (S_IRWXUGO): Define.

        * 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.

        (ftypelet): Use S_ISCTG.

        * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Use the one-arg

        * 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.

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>

        (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>

        * lib/Makefile.am: Reflect renaming.
        Reported by Eli Zaretskii.

        Use a temporary file name that won't clash with `charset.alias'

        * 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>

        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

2000-03-06  Jim Meyering  <meyering@lucent.com>

        * lib/localcharset.c (get_charset_aliases): Don't try to free file_name

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.

        i18n mailing list.  From Bruno Haible.

2000-03-04  Bruno Haible  <haible@clisp.cons.org>

        * m4/codeset.m4: New file.

2000-03-02  Jim Meyering  <meyering@lucent.com>

        rather than jm_CHECK_DECLARATIONS.

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

        Declare malloc if needed.

        * lib/backupfile.c: Use `#if !HAVE_DECL...' instead of
        `#ifndef HAVE_DECL..'

        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.

        (_ 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.

2000-02-09  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

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

        * 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.

        * lib/nanosleep.c (nanosleep):
        Don't use SA_INTERRUPT to decide whether to call sigaction, as
        POSIX.1 doesn't require SA_INTERRUPT and some systems
        (e.g. Solaris 7) don't define it.  Use SA_NOCLDSTOP instead;
        it's been part of POSIX.1 since day 1 (in 1988).
