[gnulib.git] / lib / ChangeLog

2001-12-02  Jim Meyering  <meyering@lucent.com>

        * tempname.c: Don't declare getenv, thus reverting the change of
        2001-11-18.  It's no longer necessary, now that stdlib.h is always
        included.

        * regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

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

        * xstrdup.c: Include xalloc.h, so that xstrdup is declared
        before being defined.

2001-11-27  Paul Eggert  <eggert@twinsun.com>

        * quotearg.h (quotearg_n, quotearg_n_style):
        First arg is int, not unsigned.
        * quotearg.c (quotearg_n, quotearg_n_style): Likewise.
        (SIZE_MAX, UINT_MAX): New macros.
        (quotearg_n_options): Abort if N is negative.
        Avoid overflow check on hosts where size_t is 64 bits and int
        is 32 bits, as overflow is impossible there.
        Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <meyering@lucent.com>

        * tempname.c: Merge with version from libc.
        * regex.c: Likewise.

        * tempname.c: Include stdlib.h unconditionally.  On some old systems
        for which STDC_HEADERS is 0, it was not included, resulting in a
        warning about an integer-to-pointer conversion problem with getenv.
        Reported by Volker Borchert.

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

        * gtod.h: Remove file.
        * Makefile.am (libfetish_a_SOURCES): Remove gtod.h.
        * gettimeofday.c: Don't include gtod.h.
        (GTOD_init): Remove function.
        (rpl_gettimeofday): Do its job here instead, rather than aborting.
        Suggestion from Volker Borchert.

2001-11-23  Jim Meyering  <meyering@lucent.com>

        * hash.h (struct hash_table): Don't define here.  Merely declare it.
        * hash.c (struct hash_table): Define it here instead.

2001-11-22  Jim Meyering  <meyering@lucent.com>

        * hash.h: Bracket contents of file with #ifndef HASH_H_ ... #endif.

2001-11-18  Paul Eggert  <eggert@twinsun.com>

        * tempname.c (TMP_MAX): Remove; no longer needed.
        (TEMPORARIES): New macro.
        (__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
        removes an artificial limitation (e.g. HP-UX 10.20, where
        TMP_MAX is 17576).

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
        on SunOS4.

        * Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
        files will be created before anything else.

2001-11-17  Jim Meyering  <meyering@lucent.com>

        * modechange.c (mode_adjust): Fix error introduced on 1999-04-26
        that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
        rather than group writable.  Patch by Juan F. Codagnone.

        * readtokens.c: Remove explicit declarations of xmalloc and xrealloc,
        Instead, include "xalloc.h".

        * mountlist.c: Include unlocked-io.h after all system headers.
        Remove explicit declarations of xmalloc, xrealloc,
        and xstrdup.  Instead, include "xalloc.h".

        * argmatch.c, closeout.c, error.c, exclude.c: Include unlocked-io.h.
        * fatal.c, getdate.y, getpass.c, getstr.c, getusershell.c: Likewise.
        * mountlist.c, posixtm.c, readtokens.c, readutmp.c: Likewise.

        * regex.c, sha.c, version-etc.c, yesno.c: Likewise.
        Reported by Padraig Brady.

        * mkstemp.c: #undef mkstemp.
        Include config.h.
        (rpl_mkstemp): Rename from mkstemp.
        Protoize.

2001-11-16  Jim Meyering  <meyering@lucent.com>

        * physmem.c [HAVE_SYS_PSTAT_H]: Include <sys/pstat.h>.
        (physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to
        determine the amount of total physical memory, use pstat_getstatic.
        HPUX-11 doesn't define _SC_PHYS_PAGES.
        (physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]:
        If sysconf couldn't be used to determine the amount of available
        physical memory, use both pstat_getstatic and pstat_getdynamic.
        Based on a patch from Bob Proulx.

2001-11-05  Jim Meyering  <meyering@lucent.com>

        * xstat.in (slash_aware_lstat): Correct a misleading comment.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args
        in argmatch_to_argument call.

        * dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an
        argument.

        * hash.c (hash_clear): Fix a bug that could lead to an infloop or
        e.g., a fault due to an attempt to free a NULL pointer.

2001-11-01  Jim Meyering  <meyering@lucent.com>

        * dirfd.c, dirfd.h: New files.
        * Makefile.am (libfetish_a_SOURCES): Add dirfd.h.

        * hash.c (hash_print) [TESTING]: Clean up.

2001-10-22  Paul Eggert  <eggert@twinsun.com>

        * hard-locale.c (alloca): Define to __builtin_alloca if __GNUC__,
        to avoid a warning if -Wall.

2001-10-21  Paul Eggert  <eggert@twinsun.com>

        * regex.c (uintptr_t): Remove macro and decl; it's config.h's job.

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

        * obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,
        this code would end up calling gettext even in packages built
        with --disable-nls.
        * getopt.c (_): Likewise.
        * regex.c (_): Likewise.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * error.c (strerror_r): Do not declare unless !_LIBC.
        Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P.
        Use strerror_r that is only a macro, even if it is not a function.
        (strerror): Check for HAVE_DECL_STRERROR before declaring.
        (private_strerror): Use prototypes, not old-style function definition.
        (print_errno_message): New function.
        Support the POSIX 'int'-flavored strerror_r, as well as the traditional
        char*-flavored one.
        (error_tail, error, error_at_line): Use it.

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

        * argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...
        and quote_n (1, ... to avoid clobbering a buffer.

2001-10-05  Jim Meyering  <meyering@lucent.com>

        * Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and hash-pjw.h.
        * hash-pjw.c: New file (factored out of fileutils' remove.c).
        * hash-pjw.h: New file.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * mountlist.c [MOUNTED_GETFSSTAT]:
        Include <sys/ucred.h>, for Apple Darwin.
        Include sys/mount.h and sys/fs_types.h only if available.
        (FS_TYPE): Define.
        (read_filesystem_list): Use FS_TYPE.

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

        * exclude.c (excluded_filename): 0 -> false, since it's
        a boolean context.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

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

        * xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL.
        (strtoul): Do not declare if HAVE_DECL_STRTOUL.
        (strtoimax, strtoumax): Do not declare if already defined as a macro.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        Most macros in unlocked-io.h had the wrong number of arguments.
        * gen-uio: New script.
        (USE_UNLOCKED_IO): Define to 1 if not already defined.
        * unlocked-io.hin: Remove file.
        * Makefile.am (unlocked-io.h): Rewrite to use a separate script,
        rather than trying to embed it here.
        (EXTRA_DIST): Add gen-uio.  Remove unlocked-io.hin
        Reported by Padraig Brady.

2001-09-25  Volker Borchert  <bt@teknon.de>

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

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * mountlist.c: Remove useless parentheses in #if directives.
        (MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when
        the deprecated MOUNTED symbol is no longer defined in mntent.h.

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

        * localcharset.c: Update from latest gettext.
        * config.charset: Likewise.

2001-09-20  Jim Meyering  <meyering@lucent.com>

        * xstrtol.c (strtoimax): Guard declaration with
        `#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
        The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
        have their own, conflicting declaration of strtoimax in sys/inttypes.h.
        (strtoumax): Likewise, for completeness (it wasn't necessary).

2001-09-06  Paul Eggert  <eggert@twinsun.com>

        * strtoimax.c (HAVE_LONG_LONG):
        Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.
        (strtoimax): Use sizeof (long), not sizeof strtol (ptr, endptr, base),
        to work around bug in IBM C compiler.

2001-09-16  Jim Meyering  <meyering@lucent.com>

        * mkdir.c: New file.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Revert some of the previous change; intead,
        fix the HAVE_GETCWD_NULL code to behave more like the
        !HAVE_GETCWD_NULL code used to.

        Include "xalloc.h".
        (xgetcwd): Do not return NULL when memory is exhausted; instead,
        invoke xalloc_die.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
        Use ssize_t, not int, to store result of readlink.
        Check for ssize_t overflow as well as size_t overflow,
        as POSIX says the result of readlink is implementation-defined
        when ssize_t overflows.
        Remove unnecessary cast to char*.
        Use free+malloc instead of realloc, as the storage doesn't need
        to be preserved and it's clearer and can be more efficient that way.
        (SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
        * xreadlink.h (xreadlink): Update prototype.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (fnmatch_no_wildcards): Fix confusion between
        usage of FNM_CASEFOLD and FNM_LEADING_DIR.  The bug was
        spotted by Jim Meyering.

2001-09-03  Jim Meyering  <meyering@lucent.com>

        * xreadlink.c (xreadlink): Preserve errno around `free' during failure.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
        like the HAVE_GETCWD_NULL code.
        Include pathmax.h if not HAVE_GETCWD.
        Do not include xalloc.h.
        (INITIAL_BUFFER_SIZE): New symbol.
        Do not use xmalloc / xrealloc, since the caller is responsible for
        handling errors.  Preserve errno around `free' during failure.
        Do not overrun buffer when using getwd.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
        __GLIBC__ && __GLIBC__ >= 2), to decide whether to use getcwd (NULL, 0).

2001-09-02  Jim Meyering  <meyering@lucent.com>

        * error.c: Update from GNU libc.

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

        * xreadlink.c: New file.
        * xreadlink.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and xreadlink.h.

        * regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
        doesn't conflict with sparc-sun-solaris2.7's definition in
        /usr/include/sys/int_types.h.

        * exclude.c: Use `""', not `<>' to #include non-system header files.
        (fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
        and strncasecmp as r-values.  Unixware didn't have declarations.

2001-08-31  Jim Meyering  <meyering@lucent.com>

        * xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
        Use an initial, malloc'd, buffer of length 128 rather than
        a statically allocated one of length 1024.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Don't include pathmax.h.
        Include stdlib.h and unistd.h if available.
        Include xalloc.h.
        (xmalloc, xstrdup, free): Remove decls.
        (xgetcwd): Don't assume sizes fit in unsigned.
        Check for overflow when computing sizes.
        Simplify reallocation code.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.

        * strtoimax.c: Renamed from strtoxmax.c, removing the
        old strtoimax.c.

        Also, make the following further changes to make this file's
        configuration more similar to that of strtol.c:
        (UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
        (strtoumax, uintmax_t, strtoull, strtol): Remove.
        (intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
        (strtoimax): Renamed from strtoumax.  All uses of unsigned values
        changed to signed values.

        And make the following changes as well:
        Fix copyright notice, as 1999 was missing.
        (verify): New macro.
        (strtoimax): Check sizes at compile-time, not run-time.
        Prefer strtol to strtoll if both work.
        (main): Remove; it was not that useful and was a pain to maintain.

        * strtoumax.c: Include strtoimax.c, not strtouxmax.c.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * savedir.c (savedir): Remove size parameter, as POSIX says that
        a directory's st_size can have an arbitrary value, so the old
        usage could waste an arbitrary amount of memory.  All uses
        changed.
        * savedir.h: Update prototype.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * xstrtol.c (strtoimax): New decl.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

        * xstrtol.h: Add copyright notice.
        (_DECLARE_XSTRTOL): Improve quality of diagnostic for
        LONGINT_INVALID_SUFFIX_CHAR.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
        tm to be declared.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * hash.c: Remove '2001' from copyright notice.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * full-write.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add full-write.h.
        * full-write.c: Correct credits, as cccp.c no longer
        exists and anyway it was so heavily changed from the old cccp
        code as to be unrecognizable.  Include full-write.h.
        (full_write) Return size_t, with short writes meaning failure.
        All callers changed.  This fixes a bug with large buffers
        on 64-bit hosts.
        * utime.c: Include full-write.h.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Merge 'exclude' changes from tar 1.13.22.
        This fixes one or two unlikely storage allocation overflow bugs,
        but doesn't change user-visible behavior otherwise.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (bool): Declare, perhaps by including stdbool.h.
        (<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
        (<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
        Include if available.
        (<xalloc.h>): Include
        (SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
        (verify): New macro.  Use it to verify that EXCLUDE macros do not
        collide with FNM macros.
        (struct patopts): New struct.
        (struct exclude): Use it, as exclude patterns now come with options.
        (new_exclude): Support above changes.
        (new_exclude, add_exclude_file):
        Initial size must now be a power of two to simplify overflow checking.
        (free_exclude, fnmatch_no_wildcards): New function.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.
        (excluded_filename, add_exclude):
        Add support for the fancy new exclusion options.
        (add_exclude, add_exclude_file): Now takes int options arg.
        Check for arithmetic overflow when computing sizes.
        (add_exclude_file): xrealloc might modify errno, so don't
        realloc until after errno might be used.

        * exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS):
        New macros.
        (free_exclude): New decl.
        (add_exclude, add_exclude_file): Now takes int options arg.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * alloca.c (alloca): Arg is of type size_t, not unsigned.

2001-08-27  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c

        * version-etc.c (N_): Remove definition.
        Revert most of last change.
        Instead, simply don't mark the `Copyright...' string for translation.
        Based on advice from Paul Eggert.

        * strtoxmax.c: Tweak comment.

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * version-etc.c (version_etc_copyright_fmt): Replace literal year
        of copyright with `%s' so translators don't get an untranslated
        message in 2002.
        (COPYRIGHT_YEAR): Define.
        (version_etc): Use fprintf rather than fputs.
        Suggestion from Ulrich Drepper.

        * Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.

        * strtoll.c: New file, from GNU libc.
        * xstrtoimax.c: New file.

        * xstrtol.h: Add xstrtoimax.
        * strtoumax.c: New file.  Simply include "strtoumax.c".
        * strtoimax.c: New file.  Likewise, but first define STRTOUXMAX_SIGNED.

        * strtoumax.c: Factor to work both for unsigned and signed types, ...
        * strtoxmax.c: ... then renamed to this.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (unlocked-io.h): Do not append "_unlocked" twice.
        Port to Solaris 8, where 'sed' requires a space after the 'r'
        command, and where sh dislikes "$/".  Clean up the spacing a bit.
        Redirect output to $tmp just once.

2001-08-12  Paul Eggert  <eggert@sic.twinsun.com>

        * addext.c (<errno.h>): Include.
        (errno): Declare if not defined.
        (addext): Work correctly when pathconf returns -1 and leaves
        errno alone because there is no limit.  Also, work even if
        pathconf returns a value greater than SIZE_MAX.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        * xgetcwd.c (xgetcwd) [defined __GLIBC__ && __GLIBC__ >= 2]:
        Simply `return getcwd (NULL, 0);'.
        [! (defined __GLIBC__ && __GLIBC__ >= 2)]:
        Use 1300 as initial value for length, not PATH_MAX.

        * pathmax.h: Clean up cpp syntax.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        * gettimeofday.c: New file.
        * gtod.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add gtod.h.

2001-08-04  Jim Meyering  <meyering@lucent.com>

        * error.h (__attribute__): Remove `|| __STRICT_ANSI__' from #if stmt,
        to get in sync with glibc.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible.

        * mbswidth.h (MBSW_REJECT_UNPRINTABLE, MBSW_REJECT_INVALID):
        Renamed from MBSW_ACCEPT_UNPRINTABLE and MBSW_ACCEPT_INVALID
        with inverted sense.  All uses changed.

        * mbswidth.c: Don't include <limits.h>.
        Include <stdlib.h> and <string.h> unconditionally.
        (iswcntrl, mbsinit, ISCNTRL): New macros.
        (mbsnwidth): Use K&R style function declarations.
        Don't bother checking for MB_LEN_MAX == 1, since the compiler
        can optimize it when MB_CUR_MAX == 1.
        The width of control characters is zero, not 1.

2001-07-15  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (EXTRA_DIST): Add unlocked-io.hin.
        (BUILT_SOURCES): Add unlocked-io.h.
        (io_functions): Define.
        (unlocked-io.h): New rule.
        (DISTCLEANFILES): Add unlocked-io.h.
        (all-local): Depend on unlocked-io.h, to ensure it is created.

        Remove a thus-exposed (better checks in automake) duplicate and
        two unnecessary .h files.

2001-06-11  Jim Meyering  <meyering@lucent.com>

        * regex.c: Update from GNU libc.

        * argmatch.c: Include "quote.h".
        (argmatch_invalid): Remove explicit `' quotes.  Instead, use the
        quote function.  Reported by Göran Uddeborg.

2001-05-20  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * dirname.c (dir_name): Compute append_dot using path, not newpath
        which is not yet declared.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (libfetish_a_SOURCES):
        Add strftime.c, since we now compile it on all hosts.

        * strftime.c (my_strftime):

        (ns): New macro.
        (my_strftime function): Add %N format.
        (emacs_strftimeu): Renamed from emacs_strftime,
        with extra ut argument.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        dirname code cleanup.  base_name now behaves more compatibly
        with POSIX basename when given file names that have trailing
        slashes, and similarly for dir_name.  Add new primitives
        base_len and dir_len.  Put the directory-name-related decls
        into dirname.h.

        * addext.c (ISSLASH, base_name): Remove; now in dirname.h.
        * backupfile.c (base_name): Likewise.
        * basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
        * dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
        * makepath.c (strip_trailing_slashes): Likewise.
        * path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN, ISSLASH):
        Likewise.
        * rename.c (strip_trailing_slashes): Likewise.
        * same.c (base_name): Likewise.
        * stripslash.c (ISSLASH): Likewise.

        * addext.c: Include <dirname.h> after size_t is defined.
        * backupfile.c: Likewise.

        * addext.c (addext): Use base_len to trim redundant
        trailing slashes instead of doing it ourselves.
        But do not trim the last slash if it is not redundant.

        * backupfile.c (find_backup_file_name,
        max_backup_version): Use base_len instead of rolling it ourselves.
        Handle the case of "" and (on DOS) "C:" correctly.

        * basename.c: Do not include <stdio.h>, <assert.h>; no longer needed.
        Include <string.h>, <dirname.h>.
        (base_name): Allow file names ending in slashes, other than names
        that are all slashes.  In this case, return the basename followed
        by the slashes.  This is more general, and can be used in places
        where the original base_name purposely had an assertion failure.
        (base_len): New function.

        * dirname.c: Include <string.h> instead of <stdlib.h>.
        Do not include <assert.h>; no longer needed.
        Include xalloc.h.
        (memrchr): Remove decl.
        (dir_name_r): Remove.
        (dir_len): Renamed from dirlen.  All callers changed.
        Rewrite in terms of base_name, for simplicity and consistency.
        (dir_name): Never return NULL.  All callers changed.
        Do not include <stdlib.h> in test program; no longer needed.
        return 0; is fine for test program.

        * dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN):
        New macros.
        (base_name, base_len, dir_len, strip_trailing_slashes): New decls.

        * path-concat.c (path_concat): Use base_len to compute
        base length, not strlen; this means we cannot rely on memcpy
        to null-terminate.

        * same.c (STREQ): Remove.
        (same_name): Handle the case where the basename ends in trailing '/'.

        * stripslash.c (strip_trailing_slashes): Return nonzero if
        a slash was stripped.  Do not strip the last slash after a
        file system prefix.

2001-04-08  Jim Meyering  <meyering@lucent.com>

        * getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
        recomputed; that's necessary when the offset spans a DST transition.
        Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.

2001-04-02  Jim Meyering  <meyering@lucent.com>

        * regex.h, regex.c: Update from GNU libc.

2001-03-16  Paul Eggert  <eggert@twinsun.com>

        * tempname.c (uint64_t): Define to uintmax_t if
        not defined, and if UINT64_MAX is not defined.
        Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
        Reported by John David Anglin.

2001-03-10  Bruno Haible  <haible@clisp.cons.org>

        * localcharset.c (locale_charset): Allow wildcard syntax. Also resolve
        alias if codeset is empty.
        * config.charset (BeOS): Use wildcard syntax.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * path-concat.c (path_concat) [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]:
        Don't insert a backslash when concatenating e.g., `C:' and `foo'.
        From Bruno Haible.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        * localcharset.c (locale_charset): Don't use setlocale(LC_CTYPE,NULL).
        Don't return NULL.

        support for DOS/DJGPP.

2001-02-28  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (libfetish_a_SOURCES):
        Add dup-safer.c, fopen-safer.c.
        (noinst_HEADERS): Add stdio-safer.h, unistd-safer.h.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        The mkstemp replacement is taken from glibc 2.2.2, with some
        portability fixes for use outside glibc, as follows:

        * tempname.c (struct_stat64): New macro.
        (direxists, __gen_tempname): Use it.
        This avoids a portability problem with Solaris 8.

        * tempname.c (<config.h>): Include if HAVE_CONFIG_H.
        (<stddef.h>, <stdint.h>, <string.h>):
        Include only if STDC_HEADERS || _LIBC.
        (<fcntl.h>): Include only if HAVE_FCNTL_H || _LIBC.
        (<unistd.h>): Include only if HAVE_UNISTD_H || _LIBC.
        (<sys/time.h>): Include only if HAVE_SYS_TIME_H || _LIBC.
        (__set_errno): Define this macro if <errno.h> doesn't.
        (P_tmpdir, TMP_MAX, __GT_FILE, __GT_BIGFILE, __GT_DIR, __GT_NOCREATE):
        Define these macros if <stdio.h> doesn't.
        (S_ISDIR, S_IRUSR, S_IWUSR, S_IXUSR):
        Define these macros if <sys/stat.h>
        doesn't.  Ignore <sys/stat.h> S_ISDIR if STAT_MACROS_BROKEN.
        (stat64, __getpid, __gettimeofday, __mkdir, __open, __open64, lxstat64,
        __xstat64): Define if not _LIBC.
        (__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC).
        (__gen_tempname): Invoke gettimeofday only if
        HAVE_GETTIMEOFDAY || _LIBC;
        otherwise, fall back on plain "time".
        Use macros like S_IRUSR | S_IWUSR rather than octal values like 0600.

        * mkstemp.c (__GT_FILE): Define to zero if not defined.

        * mkstemp.c, tempname.c: New files, taken from glibc 2.2.2.

2001-02-17  Jim Meyering  <meyering@lucent.com>

        * strtoul.c: Sync from GNU libc.  Use double quotes, not <...>
        around included file name.

        * strnlen.c (__strnlen): Merge in a change from GNU libc.

        * strftime.c: Update from GNU libc (the only changes were to comments).

2001-02-13  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h (mbswidth): Also define as macro, to avoid prototype clash.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * mbswidth.c, quotearg.c (mbrtowc, mbsinit):
        Remove workaround macros for hosts that have mbrtowc but not
        mbstate_t, as we now insist on proper declarations for both
        before using mbrtowc.

2001-02-17  Jim Meyering  <meyering@lucent.com>

        * regex.c: Update from libc.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

        * alloca.c (malloc): Undef before defining, since stdlib.h
        may have defined it.  Needed for Encore Umax-3.0.9.16b systems.
        Reported by Mark Hounschell via Paul Eggert.

2001-01-30  Bruno Haible  <haible@clisp.cons.org>

        line in double quotes so that it evokes a better diagnostic.
        [HAVE_DONE_WORKING_REALLOC_CHECK]: Likewise.
        Reported by Axel Kittenberger.

2001-01-15  Bruno Haible  <haible@clisp.cons.org>

        * unicodeio.c (print_unicode_char): Cast the second iconv() arg,

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

        * basename.c: Include <stdio.h>, needed by assert on SunOS4.
        From Bruno Haible.

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

        Include stdlib.h, string.h or strings.h, and xalloc.h.
        Use strip_trailing_slashes rather than open-coding it.

2001-01-03  Paul Eggert  <eggert@twinsun.com>

        * strftime.c: Sync with glibc time/strftime.c 1.81.

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

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

2000-12-29  Paul Eggert  <eggert@twinsun.com>

        * modechange.c: Do not assume that mode_t uses the
        traditional octal encoding.  E.g. "chmod 1 FOO" should set
        the other-execute bit of FOO even if S_IXOTH != 1.

        (SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
        WOTH, XOTH, ALLM): New macros.
        (S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR,
         S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH):
        Use them.
        (S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
        (S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
        (mode_compile):
        No need to use uintmax_t; unsigned long is long enough.
        Don't bother to get suffix since we don't use it.

2000-12-24  Jim Meyering  <meyering@lucent.com>

        * hash.c (is_prime): Return explicit boolean values.
        (hash_get_first): Return NULL to appease Irix5.6's 89.
        Reported by Nelson Beebe.

2000-10-31  Bruno Haible  <haible@clisp.cons.org>

2000-12-18  Bruno Haible  <haible@clisp.cons.org>

        * config.charset: Add support for BeOS.

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

2000-12-16  Jim Meyering  <meyering@lucent.com>

        This bug had a serious impact on chown: `chown N:M FILE' (for integer
        N and M) would have treated it like `chown N:N FILE'.

        * userspec.c (parse_user_spec): Fix typo: s/u/g/.

2000-10-31  Bruno Haible  <haible@clisp.cons.org>

        * config.charset: Add ISO-8859-3, BIG5HKSCS, GB18030, JOHAB, VISCII,
        CP874, CP949, CP950, CP1250, CP1253, CP1254, CP1255, CP1256, CP1257
        to the list of canonical encodings. Rename EUC-CN to GB2312.

2000-12-08  Andreas Schwab  <schwab@suse.de>

        * mbswidth.c (mbsnwidth): Don't loop endlessly when called with an
        invalid mulitbyte sequence and with the MBSW_ACCEPT_INVALID flag set.

2000-12-07  Jim Meyering  <meyering@lucent.com>

        * stripslash.c (ISSLASH): Define.
        (strip_trailing_slashes): Use ISSLASH rather than comparing against `/'.
        From Prashant TR.

        * dirname.c (FILESYSTEM_PREFIX_LEN): Define.
        (dir_name_r): Declare this function as static.
        [BACKSLASH_IS_PATH_SEPARATOR]: Fix a bug that'd
        manifest itself on a name containing a mix of slashes and
        backslashes.
        Make this function work with names starting with a DOS-style
        drive letter and colon prefix.
        (dir_name): Append `.' if necessary.
        Based mostly on patches from Prashant TR and Eli Zaretskii.

        * dirname.h (dir_name_r): Remove prototype.

2000-12-05  Jim Meyering  <meyering@lucent.com>

        * dirname.c (dir_name_r): Add `const' in a few local declarations.

2000-12-04  Jim Meyering  <meyering@lucent.com>

        * path-concat.c: [!HAVE_DECL_MALLOC]: Declare malloc.
        Also include memory.h, stdlib.h, unistd.h if appropriate.
        Reported by Andreas Jaeger (conflicting declaration of malloc).

2000-12-02  Jim Meyering  <meyering@lucent.com>

        * closeout.h: Make idempotent, to avoid some obscure warnings.

2000-12-01  Paul Eggert  <eggert@twinsun.com>

        * memrchr.c: Include <config.h> before any system include file.

2000-11-29  Paul Eggert  <eggert@twinsun.com>

        * dirname.c (dir_name_r): Fix typo: int -> size_t.

2000-11-26  Jim Meyering  <meyering@lucent.com>

        * memcoll.c: Include sys/types.h.  From Werner Almesberger.

2000-11-22  Paul Eggert  <eggert@twinsun.com>

        * strftime.c (my_strftime): Do not invoke mbrlen with a
        size of (size_t) -1; it's not portable.

2000-11-17  Akim Demaille  <akim@epita.fr>

        * obstack.h: Formatting changes.
        (obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
        prevent type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'
        variable is valid.
        (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

2000-11-17  Jim Meyering  <meyering@lucent.com>

        * strstr.c: Update from GNU libc.

2000-11-16  Jim Meyering  <meyering@lucent.com>

2000-11-06  Paul Eggert  <eggert@twinsun.com>

        * getusershell.c (setusershell): Use rewind rather than
        fseek/fseeko, to avoid configuration hassles with fseeko.
        Don't bother opening SHELLS_FILE if shellstream is NULL;
        it's not necessary.

2000-11-05  Jim Meyering  <meyering@lucent.com>

        * makepath.h (make_dir): Declare.
        * makepath.c (make_dir): Remove `static' attribute.

        last one in a bucket, advance to the next bucket.

2000-11-02  Vesselin Atanasov  <vesselin@bgnet.bg>

        * fnmatch.c: Do not comment out all the code if we are using
        the GNU C library, because in some cases we are replacing buggy
        code in the GNU C library itself.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * error.h, getline.h, modechange.h:
        Remove "2000" from Copyright line, as the file hasn't been
        changed this year other than in the copyright notice.

        * xalloc.h: Add "2000" to Copyright line, as this file
        was changed this year.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * fnmatch.c (FOLD): Do not assume that characters are unsigned.
        (fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,
        e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero.

2000-10-29  Greg Louis  <glouis@dynamicro.on.ca>

        * regex.h (__restrict_arr): Move definition out of #ifndef block.
        Required because egcs-2.91.66 (aka 1.1.2) defines __restrict, but
        doesn't define __restrict_arr.

2000-10-29  Jim Meyering  <meyering@lucent.com>

        * xstat.in: Fix grammar in comment.

2000-10-28  Jim Meyering  <meyering@lucent.com>

        * memchr.c: Update from libc.
        Adjust for portability:
        [HAVE_STDLIB_H]: Include stdlib.h.
        [HAVE_BP_SYM_H || _LIBC]: Guard inclusion of bp-sym.h.
        Undef __memchr, too.
        [!weak_alias]: Define __memchr to memchr.

        * regex.c: Update from libc.
        * regex.h: Likewise.
        * getopt1.c: Likewise.
        * memcmp.c: Likewise.

        * getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.
        Avoid using fseek, when possible -- it's broken by design.
        Patch by Ulrich Drepper.

2000-10-26  Jim Meyering  <meyering@lucent.com>

        * strftime.c: Update from libc.

2000-10-25  Jim Meyering  <meyering@lucent.com>

        * obstack.c: Update from libc.

2000-10-23  Jim Meyering  <meyering@lucent.com>

        * hard-locale.c (hard_locale): Revert last change -- it was simply
        wrong.  That set_locale call must not have any side effects.
        From Paul Eggert.

2000-10-22  Jim Meyering  <meyering@lucent.com>

        * md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.
        [CYCLIC]: Remove now-unused definition.

        * save-cwd.c (O_DIRECTORY): Define, if needed.
        (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".".
        Suggestion from Ulrich Drepper.

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

        * dirname.c (dir_name_r): New function, factored out of dir_name.
        (dir_name): Use dir_name_r.

        * dirname.c (memrchr): Declare if necessary.
        (dir_name): Remove the restriction that there be no
        trailing slashes.  Now, this code skips past them, effectively
        ignoring them.
        [TEST_DIRNAME] (main): New unit tests.

        * memrchr.c: New file from GNU libc.
        Undef __memrchr, too.
        [!weak_alias]: Define __memrchr to memrchr.
        Guard weak_alias use with `#ifdef weak_alias'.

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

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

        * getopt.c: Update from libc.

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

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

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

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

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

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

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

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

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

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

        * regex.c: Update from libc.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        yesno.c: Back out Copyright date changes for each file with no change
        this year.  This eases coordination with other programs using the same
        source code modules.  From Paul Eggert.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

        * diacrit.c (diacrit_diac): Use __MSDOS__ in favor of MSDOS.
        * dirname.c (dir_name): Likewise.

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

        (dir_name): Assert that there are no trailing slashes.

2000-07-18  Bruno Haible  <haible@clisp.cons.org>

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

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

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

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

        * mbswidth.c (_XOPEN_SOURCE):
        Don't define; this causes problems on Solaris 7.
        (wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.

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

        * quotearg.c:
        Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        so that mbstate_t is always defined.

        Do not inspect MB_LEN_MAX, since it's incorrectly defined to
        be 1 in at least one GCC installation, and this configuration
        error is likely to be common.  Ignoring MB_LEN_MAX hurts
        performance on hosts that have mbrtowc but have only unibyte
        locales, but I assume these hosts are rare.

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

        * quotearg.c: Streamline by invoking multibyte code only if needed.
        <wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX.
        (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX).
        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

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

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

2000-07-15  Bruno Haible  <clisp.cons.org>

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

2000-07-16  Bruno Haible  <haible@clisp.cons.org>

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

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

        * config.charset: Add support for FreeBSD. Improve support for HP-UX
        and IRIX 6.

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

        * makepath.c: Include quote.h.
        (make_path): Convert "`%s'" in format strings to "%s", and wrap each
        corresponding argument in a `quote (...)' call.
        Give better diagnostics.

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

        * quote.c (quote, quote_n): New file.  Two functions taken verbatim
        from tar's src/misc.c.
        * quote.h: New file.  Prototypes for same.

2000-07-10  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

2000-07-13  Paul Eggert  <eggert@twinsun.com>

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

        * quotearg.c (quoting_style_args, quoting_style_vals,
        quotearg_buffer_restyled): Add support for
        clocale_quoting_style.  Undo previous change to
        locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
        and "{RIGHT QUOTATION MARK}" msgids.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

        The old behavior of quoting `like this' doesn't look good with
        newer, ISO-style fonts.  See:
        http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

        Instead, quote "like this" by default.  Let the translator
        tailor the locale-specific quoting behavior by providing
        translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

        * quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use
        gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
        gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.

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

        * Most files: Update copyright dates to include 2000.

2000-07-08  Jim Meyering  <meyering@lucent.com>

        * xgethostname.c (ENAMETOOLONG): Define to an unlikely value
        if not defined.
        (xgethostname): Remove now-unnecessary #ifdef.
        Move declaration of `err' into loop where it's used.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * xgethostname.c (xgethostname): Protect against the SunOS5.5 bug
        by allocating a larger buffer. Test the gethostname return value for
        being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
        returns an error and ENAMETOOLONG isn't defined.

2000-07-05  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (mbrtowc): Declare returned type, since BeOS doesn't.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (struct quoting_options): Simplify quote_these_too
        dimension.

2000-07-03  Jim Meyering  <meyering@lucent.com>

        * strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
        Reported by Bruno Haible.

2000-07-04  Jim Meyering  <meyering@lucent.com>

        * quotearg.c: Make inclusion of <wchar.h> independent of whether
        HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
        lacks mbrtowc.

2000-07-03  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (mbrtowc):
        Assign to *pwc, and return 1 only if result is nonzero.
        (iswprint): Use ISPRINT when substituting our own mbrtowc.

2000-07-03  Jim Meyering  <meyering@lucent.com>

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

2000-07-02  Jim Meyering  <meyering@lucent.com>

        * quotearg.c (mbstate_t): Don't define here.

2000-07-02  Jim Meyering  <meyering@lucent.com>

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV,
        per change in ../m4/ls-mntd-fs.m4.
        (read_filesystem_list): Ignore symbolic links.

2000-06-29  Jim Meyering  <meyering@lucent.com>

        * same.c: Include <string.h> or <strings.h>, as appropriate,
        for declaration of strcmp.

        * long-options.c: Include <stdlib.h>, for declaration of exit.

        * mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]:
        Avoid warning by casting result to `char *' to remove `const'.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * Makefile.am (libfetish_a_SOURCES): Remove readutmp.c.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        savedir now sets errno on failure and invokes xmalloc to get memory.
        Fix a couple of other minor bugs while we're at it.

        * savedir.c (<unistd.h>): Do not include; there's no need.
        (NAMLEN): Remove macro.
        (malloc, realloc): Remove decls.
        (stpcpy): Likewise.
        ("xalloc.h"): Include.
        (NAME_SIZE_DEFAULT): New macro.
        (savedir): Use xmalloc / xrealloc to allocate memory.
        Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero.
        Skip "" directory entries.
        Use strlen to calculate directory entry length, since the old method
        is rarely used these days and isn't worth supporting.
        Don't use a pointer after freeing it.
        Check for integer overflow when calculating allocation size.
        Use memcpy to copy entries, instead of stpcpy.
        Set errno properly when returning NULL.
        Check for readdir error.

2000-06-26  Jim Meyering  <meyering@lucent.com>

        * posixtm.c [HAVE_STDLIB_H]: Include stdlib.h, for decl of abort.

        not if ! (HAVE_MBRTOWC && HAVE_WCHAR_H).

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * xgetcwd.c (xgetcwd): If the required pathname length is smaller
        than 1024, return a memory chunk of least possible size, instead
        of size PATH_MAX + 2. In the loop, increment the size proportionally.
        Use free/xmalloc instead of xrealloc to avoid copying for very long
        paths.

        Remove; no longer needed.

        efficient on some hosts.
        (close_stdout_status): Remove test as to whether stdout was already

2000-03-07  Paul Eggert  <eggert@twinsun.com>

        * savedir.c (savedir): Work even if directory size is

        not `#if STDC_HEADERS'.
        Declare malloc if needed.

        * backupfile.c: Use `#if !HAVE_DECL...' instead of `#ifndef HAVE_DECL..'
        now that autoconf always defines the HAVE_DECL_ symbols.
        * human.c: Likewise.
        * same.c: Likewise.
        * strtoumax.c: Likewise.

        * nanosleep.h (nanosleep): Guard declaration with
        `#if ! HAVE_DECL_NANOSLEEP'.
        Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
        the declaration in that vendor's sys/timers.h.
        Reported by Christian Krackowizer.

        * quotearg.c (ISASCII): Add #undef and move definition to follow
        inclusion of wctype.h to work around solaris2.6 namespace pollution.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding

2000-01-23  Jim Meyering  <meyering@lucent.com>

        (strverscmp): Use ISDIGIT, not isdigit.

2000-01-17  Paul Eggert  <eggert@twinsun.com>

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

2000-01-17  Jim Meyering  <meyering@lucent.com>

        * interlock: Remove unused file.  Reported by François Pinard.
