        and Jim Meyering  <meyering@redhat.com>

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

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

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

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

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

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

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

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

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

        * MODULES.html.sh: Mention new module.

        New module gnu-make, for determining whether we're using GNU Make.

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

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

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

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

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

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

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

        2007-07-11  Jim Meyering  <jim@meyering.net>

        depends on it.
        (xstrtol_error): Remove.

        in an exit status, or about storage management of the option argument.
        (xstrtol_error): Now a static function.  Redo signature to

        * m4/inttypes.m4 (gl_INTTYPES_H): Use GL_TRIGGER_STDC_LIMIT_MACROS

        long unreadable paths in GNU/Linux.  Problem reported by Andreas
        Schwab in
        <http://lists.gnu.org/archive/html/bug-gnulib/2007-02/msg00261.html>.

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

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

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

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

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

        * config/srclist.txt: Comment out mktime.c for now.
        * doc/gnulib-tool.texi (Initial import): Don't use time_r as an example
        since it doesn't apply any more.  Use generic wording instead.
        * MODULES.html.sh (Support for systems lacking POSIX:2001): New module
        'time'.
        * lib/time_.h, m4/time_h.m4, modules/time: New files.
        * lib/strptime.h, lib/time_r.h, lib/timegm.h: Remove.
        * lib/mktime.c: Include config.h depending on _LIBC, not HAVE_CONFIG_H.

        * lib/strftime.c: Likewise.

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

        of our own, instead of struct timespec itself.

        * 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,

        * 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

        * lib/tempname.c: Likewise.
        * lib/timespec.h: 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/sys_time_h.m4: New file.

        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

        value into a valid one.  Instead, use a change based on Matthew
        Woehlke's original patch.

        in place of literal "abort ()" uses.

        (fts_set_stat_required, cwd_advance_fd, fts_read, fd_ring_check):

        Improve support for OpenBSD.
        * build-aux/config.rpath (libname_spec): Export.
        (library_names_spec): New variable. Export.
        * m4/lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Extract libname_spec and
        library_names_spec from the config.rpath output. Locate shared library
        through the name pattern in library_names_spec.

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

        * lib/version-etc.c (COPYRIGHT_YEAR): Bump for new year.

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
        sent to bug-grep@gnu.org today.

2006-12-29  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/acl.h: Include sys/types.h and sys/stat.h, for mode_t and
        struct stat.  Problem reported by Henning Nielsen Lund.
        * lib/acl.c: Include acl.h first, to check interface.  Don't
        bother to include sys/types.h and sys/stat.h again.

2006-12-28  Paul Eggert  <eggert@cs.ucla.edu>

        Import the following change from libc; problem reported by
        Sven Verdoolaege.

        2005-10-13  Ulrich Drepper  <drepper@redhat.com>

        [BZ #1373]
        * lib/argp.h: Remove __NTH for __argp_usage inline function.

2006-12-28  Jim Meyering  <jim@meyering.net>

        * build-aux/announce-gen: Do not assume that the package
        builds any of tar.gz, tar.bz2, and .xdelta files.
        Suggestion from Simon Josefsson.

2006-12-28  Simon Josefsson  <simon@josefsson.org>

        * modules/announce-gen: New file.

2006-12-27  Paul Eggert  <eggert@cs.ucla.edu>

        * lib/mbchar.h: Just include <wctype.h>; the wctype module
        handles its gotchas now.
        * lib/mbswidth.c: Likewise.
        * lib/wcwidth.h: Likewise.
        * m4/mbchar.m4 (gl_MBCHAR): Don't bother checking for wctype.h
        and iswcntrl; the wctype module does this stuff now.
        * m4/mbswidth.m4 (gl_MBSWIDTH): Likewise.
        * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Likewise.
        * modules/mbchar (Depends-on): Add wctype.
        * modules/mbswidth (Depends-on): Likewise.
        * modules/wcwidth (Depends-on): Likewise.

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

        * lib/fnmatch.c: Reinstate inclusion of <wchar.h>, since this
        module uses more than what <wctype.h> is required to provide.

2006-12-26  Eric Blake  <ebb9@byu.net>

        * gnulib-tool (sed_extract_prog): Avoid space-tab.

2006-12-26  Eric Blake  <ebb9@byu.net>

        * modules/absolute-header: New module.
        * modules/fcntl (Depends-on): Depend on it.
        * modules/inttypes (Depends-on): Likewise.
        * modules/stdint (Depends-on): Likewise.
        * modules/sys_stat (Depends-on): Likewise.
        * modules/wctype (Depends-on): Likewise.
        * MODULES.html.sh (Support for building libraries and
        executables): Document it.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        Fix porting problem for iswctype reported by Georg Schwarz in:
        http://lists.gnu.org/archive/html/bug-coreutils/2006-12/msg00017.html
        * lib/fnmatch.c (WIDE_CHAR_SUPPORT): Require HAVE_ISWCTYPE, too.
        * lib/regex_internal.h (RE_ENABLE_I18N): Likewise.
        * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH): Check for iswctype, too.
        * m4/regex.m4 (gl_PREREQ_REGEX): Likewise.

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:
        http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=ba45154d8e9f
        Reported by Mike Frysinger.

2006-12-01  Jim Meyering  <jim@meyering.net>

        * modules/savewd (Depends-on): Add fcntl_h to avoid self-test
        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
        recommended by RMS (rather than LGPL).
        * m4/vararrays.m4: Likewise.
        * m4/flexmember.m4: Likewise.

2006-11-29  Bruno Haible  <bruno@clisp.org>

        * gnulib-tool (func_emit_lib_Makefile_am): Initialize also

        using +=.
        Reported by Simon Josefsson <simon@josefsson.org>.

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>

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

2006-11-26  Paul Eggert  <eggert@cs.ucla.edu>

        Fix some incompatibilities with gcc -ansi -pedantic.
        * 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.

        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.

2006-11-20  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.
        Problem reported by Greg Schafer.
        * modules/idcache: Likewise.

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

        * check-module (%exempt_header): Add exception for some
        conditionally-included headers.

        (License): Change to LGPL.

2006-11-16  Paul Eggert  <eggert@cs.ucla.edu>

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

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

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

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

        * m4/alloca.m4 (gl_FUNC_ALLOCA): Use AC_CACHE_CHECK to avoid a
        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'.

        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
        name to underscores for the --with option.

2006-11-13  Bruno Haible  <bruno@clisp.org>

        (func_emit_initmacro_end): Undo the override here.
        (func_emit_initmacro_done): Emit a definition for gl_LIBSOURCES.
        Works around the famous automake error in coreutils.

2006-11-13  Eric Blake  <ebb9@byu.net>

        * lib/gl_anytree_oset.h (gl_tree_search_atleast): Return the
        element, not its node.

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

        * gnulib-tool (func_emit_lib_Makefile_am): Replace occurrences of
        '$(top_srcdir)/build-aux/', taking into account the real auxdir.

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

        * 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.
        (func_import, func_create_testdir): Invoke AM_PROG_CC_C_O in this case.

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

        * gnulib-tool (func_get_automake_snippet): Synthesize also an
        EXTRA_lib_SOURCES augmentation.
        (func_emit_lib_Makefile_am): Initialize EXTRA_lib..._SOURCES to empty.

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

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

2006-11-09  Paul Eggert  <eggert@cs.ucla.edu>

        * 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
        relevant options in CFLAGS (like -O, -fno-inline) are taken into
        account.

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

        * modules/inline: New file/module.

        Problem reported by Matthew Woehlke.

2006-11-09  Bruno Haible  <bruno@clisp.org>

        * lib/tempname.c (gen_tempname): Remove variant that invokes
        __gen_tempname.
        * m4/tempname.m4 (gl_FUNC_GEN_TEMPNAME): Don't test for
        __gen_tempname.

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

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Set ac_cv_type_long_long_int
        to 'yes' instead of 'cross-compiling'.

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

        * lib/quotearg.h (quotearg_free): New decl.
        * lib/quotearg.c (quotearg_free): New function.
        (slot0, nslots, slotvec0, slotvec):
        Now file-scope so that quotearg_free can get at them.

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

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

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

        * m4/inline.m4 (gl_INLINE): Also test __NO_INLINE__.
        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>

        * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
        Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
        Matthew Woehlke.

        * lib/xalloc.h (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Move
        definitions up, to avoid colliding with change below.
        (static_inline) [HAVE_INLINE]: New macro.
        (xnmalloc, xnrealloc, x2nrealloc, xcharalloc):
        Provide extern decls when !HAVE_INLINE.  Do not define unless
        static_inline is defined, either by us or by xmalloc.c.  Use
        static_inline rather than static inline.
        (XCALLOC): Optimize sizeof(T) = 1 case.

        (gl_tree_create, gl_tree_add_first, gl_tree_add_last):
        (gl_tree_add_before, gl_tree_add_after):
        Use XMALLOC instead of xmalloc, and XCALLOC instead of xzalloc.

        * lib/gl_oset.h: Use C comment style, not C++ comment style.

2006-11-06  Bruno Haible  <bruno@clisp.org>

        * m4/inline.m4: New file.

        * modules/flexmember, m4/flexmember.m4: New files.

        * lib/xalloc.h (xnmalloc, xnrealloc, x2nrealloc): Now static
        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.

        (xnrealloc, x2nrealloc_inline, x2nrealloc): Remove.  The *_inline
        versions have been moved to lib/xalloc.h and renamed to be the
        non-*_inline versions.
        (xmalloc, xrealloc): Implement without reference to the xnmalloc
        and xnrealloc functions, since those functions are now inline and
        now call us.
        (x2realloc): Invoke x2realloc, not x2realloc_inline, to accommodate
        renaming described above.
        * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Remove AC_C_INLINE since
        xmalloc.c no longer uses inline directly.  gl_PREREQ_XALLOC now
        captures the dependency in AC_C_INLINE.

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

        (Imported from Automake.)

        * m4/signalblocking.m4 (gl_SIGNALBLOCKING): Renamed from

        request sigprocmask.o.
        (gl_PREREQ_SIGPROCMASK): New macro.
        * modules/fatal-signal (Files): Remove m4/signalblocking.m4.
        (Depends-on): Add sigprocmask.
        * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Don't require

        * 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.

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

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

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

        * m4/getloadavg.m4: Revert the change below.

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

        single configure.ac file.
        * gnulib-tool (func_emit_lib_Makefile_am): In the _LIBADD variable,
        use a private [LT]LIBOBJS variant. Define a _DEPENDENCIES variable
        with the same contents as the _LIBADD variable.
        (func_emit_initmacro_start, func_emit_initmacro_end,
        func_emit_initmacro_done): New functions.
        (func_import, func_create_testdir): Invoke them. Allow the identifiers
        gl_LIBOBJS and gl_LTLIBOBJS.

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

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

        modules.

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

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

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

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

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

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

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

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

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

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

            Bruno Haible  <bruno@clisp.org>

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

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

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

        gl_AC_TYPE_LONG_LONG.

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

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

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

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

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

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

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

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

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

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

        Don't include <config.h> twice; this doesn't work in some cases,
        e.g., when config.h has "#define intmax_t long long int" and
        we include <config.h>, <inttypes.h>, <config.h> in that order.
        Problem reported by Matthew Woehlke in:
        http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00073.html
        * lib/fprintftime.c: Don't include config.h or fprintftime.h.

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

2006-10-08  Bruno Haible  <bruno@clisp.org>

        * doc/gnulib-tool.texi: Emphasize the drawbacks of the --symlink
        option.

2006-10-07  Jim Meyering  <jim@meyering.net>

        * modules/inttypes (inttypes.h): Revert what seems to have been
        an inadvertent part of today's change: use "|", not "/" in the
        substitution for the "/"-containing string, $(ABSOLUTE_INTTYPES_H).

2006-10-07  Bruno Haible  <bruno@clisp.org>

        * lib/dirchownmod.c: Include lchown.h.
        * lib/lchown.c: Don't include files that lchown.h now includes.

        (lchown): Define to rpl_chown if lchown is declared but
        does not exist.  Declare using a prototype if lchown is not
        declared.  Add a copyright notice.
        * lib/mkstemp.h: Include <unistd.h>.
        * lib/openat.c: Include lchown.h.

        rather than O_NOFOLLOW, when testing whether it's possible to

        of O_NOFOLLOW_IS_INEFFECTIVE.  Define HAVE_WORKING_O_NOATIME if
        O_NOATIME works.

2006-09-29  Paul Eggert  <eggert@cs.ucla.edu>

        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.

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

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

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

        Import this patch from libc:

        2006-09-06  Jakub Jelinek  <jakub@redhat.com>

        * lib/regex_internal.c (re_string_reconstruct): Handle
        offset < pstr->valid_raw_len && pstr->offsets_needed case.
        Ensure no bytes read before raw_mbs array.  Pass a saved copy of
        pstr->valid_len - 1 rather than pstr->valid_raw_len - 1 to
        re_string_context_at.

        * m4/regex.m4 (gl_REGEX): Check for locale.h, since the test
        now requires it.
        (gl_PREREQ_REGEX): Don't check for locale.h any more, since
        gl_REGEX now does it for us.
        (gl_REGEX): Add test taken from
        http://sourceware.org/ml/libc-hacker/2006-09/msg00008.html.

        * m4/mkstemp.m4 (gl_FUNC_MKSTEMP): Require AC_SYS_LARGEFILE.
        Check that large offsets work.  Modernize Autoconf usages.
        Prefer "yes" to mean a good thing rather than a bad.
        Don't put "#define mkstemp" in config.h, as this might interfere
        with standard system headers that "#define mkstemp mkstemp64".

        * modules/mkstemp (Depends-on): Add extensions, so that
        mkstemp is visible on some platforms.
        (Makefile.am): Add mkstemp.h to EXTRA_DIST.
        (Include): Change to "mkstemp.h" from <stdlib.h>.
        (Files): Add mkstemp.h.

        * lib/mkstemp.h: New file, since some standard headers
        #define mkstemp.
        * lib/mkstemp.c: Revamp to put the !_LIBC code together.
        Include "mkstemp.h".
        Make the _LIBC code resemble glibc original more,
        e.g., use K&R style.
        * lib/mkstemp-safer.c: Include "mkstemp.h" instead of <stdlib.h>.
        (mkstemp): Remove, since mkstemp.h does this for us.
        * lib/stdlib--.h: Include mkstemp.h.

        Import this patch from libc:

        2006-04-07  Ulrich Drepper  <drepper@redhat.com>

        * lib/tempname.c (__gen_tempname): Change attempts_min
        into a macro.  Use preprocessor to decide how to initialize

                * sysdeps/posix/tempname.c (__gen_tempname): Change
                attempts_min into a macro.  Use preprocessor to decide how to
                initialize attempts [Coverity CID 67].

        * MODULES.html.sh (func_module): Break long lines.
        Suggested by Bruce Korb <bkorb@gnu.org>.

        * lib/dirchownmod.c: Don't include fcntl.h; no longer needed.
        (dirchownmod): New arg FD.  All callers changed.

        (test_dir): Remove.
        (mkancesdirs): Return length of prefix of FILE that has already
        been made, or -2 if there is a child doing the work.  Redo
        algorithm so that it is O(N) rather than O(N**2).  Optimize away
        ".", and treat ".." specially since it might stray back into
        already-created areas.  Use a subprocess if necessary.  New arg
        WD; all users changed.  MAKE_DIR function should now return 1
        if it creates a directory that is not readable.  Return -2 if
        a child process is spun off.
        * lib/mkancesdirs.h: Include <stddef.h>, for ptrdiff_t.
        Adjust signature to match code.
        * lib/mkdir-p.c: Include dirname.h, for IS_ABSOLUTE_FILE_NAME.

        dgettext.

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

        * lib/nanosleep.c: Include <sys/types.h> before sys/select.h, to avoid
        compilation failure (due to use of pid_t in latter) on NetBSD 1.6.
        Reported by Nelson H. F. Beebe.

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

        initialized.
        * lib/argp-namefrob.h: Move declarations of program_invocation_name
        and program_invocation_short_name to argp.h, so they are visible
        to user programs.
        * 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>

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

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

        Prefer #ifdef to #if.

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

        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.

        at the end, which is the usual gnulib style.

        * m4/fstypename.m4 (gl_FSTYPENAME): Use AC_CHECK_MEMBERS instead
        of doing all the work ourselves.
        * m4/fsusage.m4 (gl_PREREQ_FSUSAGE_EXTRA): Don't check for

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

        * lib/cycle-check.h: Include <stdint.h> unconditionally, since we

2006-08-19  Paul Eggert  <eggert@cs.ucla.edu>

2006-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        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
        and is a script that invokes bison. Tighten the code. Add comments.

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.

        * m4/ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Also check for
        sys/statvfs.h. When getmntinfo was found, check its declaration and
        set either MOUNTED_GETMNTINFO or MOUNTED_GETMNTINFO2 depending on it.

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

        * m4/bison-i18n.m4: New file, from bison.

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

        * lib/mountlist.c [MOUNTED_GETMNTINFO2]: Include sys/statvfs.h.
        (ME_DUMMY): Treat "kernfs" as a dummy.
        (read_file_system_list) [MOUNTED_GETMNTINFO2]: Implement.

2006-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        Update from coreutils.

        2006-08-15  Jim Meyering  <jim@meyering.net>

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

        * m4/fts.m4 (gl_FUNC_FTS_CORE): Depend on gl_FUNC_OPENAT.

        2006-01-11  Jim Meyering  <jim@meyering.net>

        * m4/openat.m4 (gl_FUNC_OPENAT): Require and compile fchmodat.c.
        Check for the lchmod function.

2006-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        Update from coreutils.

        * lib/__fpending.h: Add copyright notice.
        * lib/fprintftime.h: Likewise.
        * lib/savedir.c: Use (C) in copyright notice.

        2006-08-15  Jim Meyering  <jim@meyering.net>

        * 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/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.

        (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.

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

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

        * lib/dirchownmod.c, lib/dirchownmod.h, lib/mkancesdirs.c:
        * lib/mkancesdirs.h: New files.
        * lib/mkdir-p.c: Don't include alloca.h, stdio.h, sys/types.h,
        unistd.h, string.h, chdir-safer.h, dirname.h, lchmod.h, lchown.h,
        save-cwd.h.  Instead, include dirchownmod.h and mkancesdirs.h.
        (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.
        * lib/modechange.c (octal_to_mode): New function.
        (struct mode_change): New member mentioned.

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

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

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

        * gnulib-tool: Avoid space-tab.
        (--doc-base): New option, to manage files from doc.

2006-07-11  Eric Blake  <ebb9@byu.net>

        * m4/absolute-header.m4: Fix comments to match recent change.

2006-07-11  Eric Blake  <ebb9@byu.net>

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

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

2006-07-10  Derek R. Price  <derek@ximbiot.com>

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

        macros into the GNU _D_EXACT_NAMLEN.

        (savedirstream): Use _D_EXACT_NAMLEN in preference to strlen.

        * m4/absolute-header.m4 (gl_ABSOLUTE_HEADER): Use "" rather than <>
        around the absolute name, to work around a problem with the HP-UX
        11.23 native C compiler, reported by Bob Proulx.

2006-07-09  Paul Eggert  <eggert@cs.ucla.edu>

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

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

        were probably computed using the old broken crc.c?

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

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

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

        with only one argument, for Autoconf 2.60.

        warnings.

        * modules/same (Files): Add lib/same-inode.h.

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

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

        Merge from coreutils.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        Merge from coreutils.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        (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'.

        There still are some problems with reeelly weird theoretical hosts
        (e.g., 33-bit int) but it's not worth worrying about now.
        * lib/sha1.c (rol): Likewise.
        (K1, K2, K3, K4): Remove unnecessary L suffix.

        Merge regex changes from libc, removing some of our
        POSIX-conformance changes that were rejected and redoing them in a
        less-intrusive way.

        * lib/regcomp.c (re_compile_internal, init_dfa):
        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_UNMATCHED_RIGHT_PAREN_ORD, REG_NO_POSIX_BACKTRACKING):
        (REG_NO_GNU_OPS, REG_DEBUG, REG_INVALID_INTERVAL_ORD):
        (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):

        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.

        #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.

        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.

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

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

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.
        (base64_encode_alloc): Fix +1 bug on allocation failures.

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

2006-03-24  Eric Blake  <ebb9@byu.net>

        * lib/time_r.c (copy_string_result): Remove, as it is no longer used.

2006-03-22  Karl Berry  <karl@gnu.org>

        * config/srclist.txt (*setenv.[ch]): get from coreutils.

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: 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

        test to be side-effect free by storing the result in the cache
        variable gl_cv_lib_readline, and moving the assignment of
        LIBREADLINE and LTLIBREADLINE outside the COMMANDS-TO-SET-IT.
        From Ralf Wildenhues <Ralf.Wildenhues@gmx.de>.

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

        * m4/unistd_h.m4 (gl_HEADER_UNISTD): Rename, to match modules file.
        Problem reported by Juan Manuel Guerrero.

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

        * lib/c-stack.c: Include unistd.h unconditionally, since we now assume
        the unistd module.

        need unistd_.h.
        (MOSTLYCLEANFILES): Remove unistd.h-t.

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

        * build-aux/maint.mk: Add several syntax checks from CoreUtils.

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

        * build-aux/maint.mk: Add refresh-po rule, based on ideas from

2006-03-03  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de> (tiny change)

        * m4/poll.m4 (gl_FUNC_POLL): If we deem poll(2) unacceptable, use
        our replacement poll.h in any case, to avoid a differing
        declaration from a system header.  Seen on AIX.

2006-03-01  Simon Josefsson  <jas@extundo.com>

        * lib/readline.c: Fix typo, tiny patch from Stepan Kasal

2006-02-27  Jim Meyering  <jim@meyering.net>

        Revert the change of 2006-02-24, so these files can continue
        to be sync'd from gettext.
        * lib/mkdtemp.c, setenv.c, unsetenv.c: *Un*-normalize inclusion
        of `config.h'.

        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).

2006-02-07  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>

        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 :".

        #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.

        * 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.

        * lib/argp-namefrob.h: Bugfix. Remove stray #

        * 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.

        * config/srclist.txt (vasnprintf.c): sync lost.

        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.

        * 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.

        * gnulib-tool (func_import): Use "trap :" instead of "trap -" to get
        rid of a trap command. For Solaris sh.
