	* getaddrinfo.c (getaddrinfo) [defined HAVE_IPV6]: Fix typo
	that prevented coreutils 6.1 from building.  Problem reported
	by Petter Reinholdtsen.

2006-09-18  Jim Meyering  <jim@meyering.net>

	* savewd.c (savewd_restore): Don't shadow: s/status/child_status/.

2006-09-15  Paul Eggert  <eggert@cs.ucla.edu>

	* dirchownmod.c: Don't include fcntl.h; no longer needed.
	(dirchownmod): New arg FD.  All callers changed.
	Use FD rather than opening the directory ourself, as opening is
	now the caller's responsibility.
	* dirchownmod.h: Likewise.
	* mkancesdirs.c: Include <sys/types.h>, for portability to older
	hosts that require <sys/types.h> before <sys/stat.h>.  Include
	fcntl.h, savewd.h, and unistd.h, not dirname.h and stat-macros.h.
	(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.
	* mkancesdirs.h: Include <stddef.h>, for ptrdiff_t.
	Adjust signature to match code.
	* mkdir-p.c: Include dirname.h, for IS_ABSOLUTE_FILE_NAME.
	(make_dir_parents): Use a subprocess if necessary.  New arg WD;
	all users changed.
	* savewd.c, savewd.h: New files.

2006-09-15  Jim Meyering  <jim@meyering.net>

	* rename-dest-slash.c (has_trailing_slash): Use
	FILE_SYSTEM_PREFIX_LEN, for non-POSIX systems.
	(rpl_rename_dest_slash): Perform the cheaper trailing slash
	test before testing whether SRC is a directory.
	Suggestions from Bruno Haible.

	Avoid a warning about an unused variable.
	* regex_internal.c (re_dfa_add_node): Move declaration of "type"
	into the #ifdef block where it's used.

	* rename-dest-slash.c: New file.

	Reported by Nelson H. F. Beebe.

2006-09-12  Sergey Poznyakoff  <gray@gnu.org.ua>

	* argp-help.c (argp_doc): Make sure NULL is not passed to
	dgettext.

	(struct argp_option): Document the use of N_() wrappers.

	* 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_("..").

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

	* mktime.c (guess_time_tm): Fix bug where mktime

	Problem reported by Frank v Waveren in
	<http://lists.gnu.org/archive/html/bug-coreutils/2006-08/msg00298.html>.

	Sync from Libtool:

	2006-08-28  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

	* libltdl/argz.c: Use `#ifdef HAVE_CONFIG_H', to facilitate code
	sharing with gnulib.  Report by Eric Blake.

2006-08-28  Paul Eggert  <eggert@cs.ucla.edu>

	* fcntl_.h: New file.

	the fcntl module.
	* dirchownmod.c: Likewise.

	e.g., HAVE_LONG_LONG -> HAVE_LONG_LONG_INT.
	* xtime.h: Likewise.

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

	* fchmodat.c: New file, from coreutils.  This was inadvertently
	omitted in the 2006-08-17 update.  Problem reported by Jay Youngman.

	* openat-priv.h: Include <errno.h> and define ENOSYS,
	in support of the EXPECTED_ERRNO macro.

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

	(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.

	(__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.
	* fts_.h [struct FTS] (fts_cwd_fd): New member.
	[struct FTS] (fts_rft): Remove now-unused member.
	[struct FTS] (fts_cycle.state): Improve comment.

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

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

	<http://lists.gnu.org/archive/html/bug-coreutils/2006-08/msg00099.html>.

2006-08-15  Paul Eggert  <eggert@cs.ucla.edu>

	* memcoll.c (memcoll): Optimize for the common case where the
	arguments are bytewise equal.

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

	Change copyright notice from LGPL 2 to GPL 2, since that's the
	standard form used in the gnulib repository.
	* lock.c: LGPL -> GPL.
	* lock.h: Likewise.
	* strnlen1.c: Likewise.
	* strnlen1.h: Likewise.
	* tls.c: Likewise.
	* tls.h: Likewise.
	* tmpdir.c: Likewise.

	* TODO: Remove; this belongs only in coreutils.

2006-08-14  Eric Blake  <ebb9@byu.net>

	Import the following change from libc:

	2006-08-12  Ulrich Drepper  <drepper@redhat.com>

	Upstream bug 2997.
	* misc/error.c: Add space between program name and message if file
	name is missing.

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

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

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

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

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

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

	Import the following changes from libc:

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

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

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

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

	2006-04-21  Ulrich Drepper  <drepper@redhat.com>

	* posix/regex.h: Remove special handling for VMS.

	(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

	(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

	(strmode): Renamed from mode_string.
	(filemodestring): New decl.

	(S_ISPORT, S_ISWHT): New macros, if not already defined.

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

	* 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).
	* 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.
	* getcwd.c (__getcwd): When no d_ino value matches the target inode
	number, iterate through all entries again, using lstat instead.

	then save the dev-ino of the parent, instead.

	* same-inode.h (SAME_INODE): New file/macro.

	[TEST_DIRNAME]: Move into a full-blown gnulib test.
	* 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.
	* stripslash.c (strip_trailing_slashes): Use last_component, not
	base_name.  Strip redundant slashes from ///.

	* 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.

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

	* stdint_.h (_GL_STDINT_H): Renamed from _STDINT_H, to avoid
	possible collision with system files.
	(<stdio.h>, <time.h>, <wchar.h>) [defined __cplusplus && ! defined
	__STDC_CONSTANT_MACROS)]: Do not include, since we don't need
	WCHAR_MIN and WCHAR_MAX in this case.
	(<stddef.h>): Do not include; no longer needed.
	(<sys/types.h>): Include if @HAVE_SYS_TYPES_H@, not if
	(defined(__OpenBSD__) || defined(__bsdi__) || defined(__sgi)).
	(<sys/inttypes.h>): Include if @HAVE_SYS_INTTYPES_H@ &&
	!@HAVE_INTTYPES_H@, not if (defined(__FreeBSD__)
	&& (__FreeBSD__ >= 3) && (__FreeBSD__ <= 4)).
	(__STDINT_H__) [@HAVE_STDINT_H@ && defined __sgi && ! defined
	__c99]: Define, to work around IRIX <stdint.h> incompatibility.
	(@FULL_PATH_STDINT_H@) [!(defined(__sgi) && @HAVE_INTTYPES_H@ &&
	!defined(__c99))]: Include in this case too, since it's harmless
	now.
	(<inttypes.h>) [@HAVE_INTTYPES_H@]: Include, since it's no longer
	dangerous to do so.
	(@FULL_PATH_INTTYPES_H@) [(defined(__hpux) || defined(_AIX)) &&
	@HAVE_INTTYPES_H@]: Do not include, since we now include <inttypes.h>.
	(_STDINT_MIN, _STDINT_MAX): New macros.
	(int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t):
	(uint64_t, int_least8_t, uint_least8_t, int_least16_t):
	(uint_least16_t, int_least32_t, uint_least32_t, int_least64_t):
	(uint_least64_t, int_fast8_t, uint_fast8_t, int_fast16_t):
	(uint_fast16_t, int_fast32_t, uint_fast32_t, int_fast64_t):
	(uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t): Now
	macros, not typedefs; this simplifies things quite a bit.
	Use long int for all types narrower than int64_t.
	(intmax_t, uintmax_t, INTMAX_C, UINTMAX_C):
	Define in terms of long long int or int64_t or long int,
	not int64_t or int32_t.  This saves some compile-time testing.
	(INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX):
	(INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX):
	(UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX, UINT_LEAST8_MAX):
	(INT_LEAST16_MIN, INT_LEAST16_MAX, UINT_LEAST16_MAX):
	(INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX):
	(INT_LEAST64_MIN, INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST8_MIN):
	(INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX):
	(UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX):
	(INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX, INTPTR_MIN):
	(INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX):
	(PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
	(SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
	undef any previous version and define our own version, for
	simplicity and consistency with the new macros for types.
	(PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
	(SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
	Simplify definitions by using _STDINT_MIN and _STDINT_MAX
	where appropriate.  Rely on new symbols @PTRDIFF_T_SUFFIX@,
	@SIG_ATOMIC_T_SUFFIX@, @SIZE_T_SUFFIX@, @WCHAR_T_SUFFIX@,
	@WINT_T_SUFFIX@ to keep things simple here.
	(UINT8_C, UINT16_C, UINT32_C, INT64_C, UINT64_C):
	Simplify by assuming typical 8/16/32/64 host, since we're
	already doing that elsewhere anyway.
	Use (LONG_MAX >> 31 >> 31 == 1) rather than @HAVE_LONG_64BIT@,
	and assume long long int is 64 bits if available.  This
	speeds up 'configure'.

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

	Merge regex changes from libc, removing some of our

	(__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_error_msgid, __re_error_msgid_idx): Remove decls; not needed.
	(MAX): New macro.
	(re_xmalloc, re_calloc, re_xrealloc, re_x2realloc): Remove.

	(re_x2nrealloc): Remove.
	(free_state): Remove decl.

	* regexc.c (regexec, re_match, re_search, re_match_2, re_search_2):

	messages with a lowercase letter.

2006-03-11  Paul Eggert  <eggert@cs.ucla.edu>

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

	xmalloc/lstat combination.  Based on a patch from Bruno Haible.

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

	* 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.

2006-02-07  Sergey Poznyakoff  <gray@gnu.org.ua>

	* argp-namefrob.h: Restore changes accidentally lost during the
	"autoupdate" on 2005-12-12.

2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>

	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>

	* socket_.h: Set WINVER to 0x0501, to make sure getaddrinfo
	prototype is visible on mingw32.

	for mingw32.

	* gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for

2006-01-26  Paul Eggert  <eggert@cs.ucla.edu>

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

	* stdbool_.h (_Bool)
	[(! (defined __cplusplus || defined __BEOS__)

	       || (defined __SUNPRO_C && (__SUNPRO_C < 0x550 || __STDC__ == 1))
	       || defined __sgi))]:
	#define to signed char in these cases too; this simplifies
	the code (so that we don't have to worry about HP-UX, AIX, SunPRO,
	etc., separately) and makes it more conservative.

2006-01-21  Jim Meyering  <jim@meyering.net>

	Sync from the stable (b5) branch of coreutils:

	* fts.c (fts_children): Don't let close() clobber errno from
	failed fchdir().

	* 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.

	* 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.
	* 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.

	has it.
	Report and patch by Albert Chin-A-Young  <china@thewrittenword.com> on
	2005-11-26.

	* stdbool_.h (_Bool) [HP-UX cc, AIX cc,xlc]: Define as 'signed char'

	Reported by Paul Eggert on 2005-11-26.

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

	!HAVE_DECL_GETENV.
	* strndup.c [!_LIBC]: Include "strndup.h" to get prototype.
	(__strndup): Revert to K&R-style function dfns, the glibc style.
	* strnlen.c: Don't claim it's taken from glibc; it's not.
	(strnlen, __strnlen): Remove #defines and #undefs; not needed.
	Include strnlen.h first, to get prototype properly.
	(strnlen): Renamed from __strnlen.
	Remove weak alias.

2006-01-23  Ulrich Drepper  <drepper@redhat.com>

	These changes imported from libc.
	* getopt.c: Use __fxprintf instead of inline stream orientation
	test and two separate function calls.
	* strndup.c (__strndup): Add libc_hidden_def.

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

	* vasnprintf.c (VASNPRINTF): In the computation of the size of the
	temporary buffer for sprintf, take into account the precision also

2006-01-12  Simon Josefsson  <jas@extundo.com>

	* base64.c: Fix warning, reported by Bruno Haible
	<bruno@clisp.org> and patch by Paul Eggert <eggert@CS.UCLA.EDU>.

2006-01-11  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from coreutils.
	* md5.c: Fix commentary typos.

	* md5.h (__attribute__): Remove; unused.
	* sha1.c: Fix commentary to match md5 better.
	* sha1.h (struct sha1_ctx): Use a word buffer, not a byte buffer,

2006-01-10  Paul Eggert  <eggert@cs.ucla.edu>

	* regex_internal.h (BITSET_WORD_BITS):
	Work around a bug in 64-bit PGC (before version 6.1-2), where the
	preprocessor mishandles large unsigned values as if they were signed.
	Problem reported by Claudio Fontana in
	<http://lists.gnu.org/archive/html/bug-gnulib/2005-12/msg00061.html>.

2006-01-10  Simon Josefsson  <jas@extundo.com>

2006-01-09  Paul Eggert  <eggert@cs.ucla.edu>

	Sync from coreutils.
	* chdir-long.c (cdb_free): Don't bother trying to open directory
	for write access: POSIX says that must fail.
	* fts.c (diropen): Likewise.
	* save-cwd.c (save_cwd): Likewise.
	* chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
	well, for minor improvements on hosts that lack O_DIRECTORY.
	* chown.c (rpl_chown) [CHOWN_MODIFIES_SYMLINK]:
	Don't try O_WRONLY unless O_RDONLY failed wth EACCES.
	Fall back on chown if open failed with EACCES.

	* gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
	Report an error at compile-time if only a 1-second nominal clock
	resolution is found.

	* lchmod.h: New file.
	* mkdir-p.c: Include lchmod.h, lchown.h.
	(make_dir_parents): Use lchown rather than chown, and
	lchmod rather than chmod.

	* mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies
	too.  Problem with "none" reported by Bob Proulx.  Problem with
	"proc" reported by n0dalus.

	* mountlist.c: Include <limits.h>.
	(dev_from_mount_options)
	[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
	New function.  It no longer assumes "dev=" has the System V meaning
	on Linux (since it doesn't).  It also parses "dev=" more carefully.
	(read_file_system_list)
	[defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
	MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
	dev= in that case.

	* posixtm.h (PDS_PRE_2000): New macro.
	* posixtm.c (year): Arg is now syntax_bits rather than allow_century.
	All usages changed.  Reject dates outside the range 1969-1999 if

	and dup to open_safer and dup_safer, respectively.
	(openat_permissive): Fix typo in comment.

	"gettext.h"; either no longer needed or are guaranteed by openat.h.
	(_): Remove; no longer needed.
	(openat): Renamed from rpl_openat; no need for rpl_openat
	since openat.h renames openat for us.
	Replace most of the body with a call to openat_permissive,
	to avoid duplicate code.
	Port to (probably hypothetical) environments were mode_t is
	wider than int.
	(openat_permissive): Require mode arg, so that we can check
	types better.  Put it just after flags.  Change cwd failure
	indicator from pointer-to-bool to pointer-to-errno-value.
	All callers changed.
	Invoke openat_save_fail and/or openat_restore_fail if
	cwd_errno is null, so that openat can call us.
	(openat_permissive, fdopendir, fstatat, unlinkat):
	Simplify errno handling to avoid some duplicate code,
	as it's OK to set errno on success.
	* openat.h: Revamp code so that function macros depend on
	__OPENAT_PREFIX only, not also on AT_FDCWD.
	(openat_ro): Remove.  Caller changed to use openat_permissive.
	(openat_permissive): Now a macro, if not a function.
	(openat_restore_fail, openat_save_fail): Now always functions,
	since mkdirat needs them even if __OPENAT_PREFIX is defined.

	* openat-priv.h: New file, defining macros used by mkdirat.c
	and openat.c.
	* mkdirat.c: Include openat-priv.h.

	(openat_ro): Define.

	* openat.c (EXPECTED_ERRNO): New macro.
	(openat_permissive): New function -- used in remove.c rewrite.
	(all functions): Set errno just before returning, only if there
	was an actual failure.
	Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.

	Emulate openat-family functions using Linux's procfs, if possible.
	Idea and some code based on Ulrich Drepper's glibc changes.

	* openat.c: (BUILD_PROC_NAME): New macro.
	Include <stdio.h>, <string.h>, "alloca.h" and "intprops.h".
	(rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
	before falling back on save_cwd and restore_cwd.
	(fdopendir, fstatat, unlinkat): Likewise.

	* openat.c (fstatat, unlinkat): Perform the syscall directly,
	skipping the save_cwd...restore_cwd overhead, if FILE is absolute.

	* openat.c (rpl_openat): Use the promoted type (int), not mode_t,
	as second argument to va_arg.  Otherwise, some versions of gcc
	warn that `if this code is reached, the program will abort'.

2006-01-09  Andreas Gruenbacher  <agruen@suse.de>

	Sync from coreutils.

	Add POSIX ACL support
	* acl.h (copy_acl, set_acl): Add declarations.
	* acl.c (acl_entries): Add fallback implementation for POSIX ACL
	systems other than Linux.
	(chmod_or_fchmod): New function: use fchmod when possible,
	and chmod otherwise.
	(file_has_acl): Add a POSIX ACL implementation, with a
	Linux-specific subcase.
	(copy_acl): Add: copy an acl and S_ISUID, S_ISGID, and
	S_ISVTX from one file to another.  Fall back to fchmod/chmod when
	acls are unsupported.
	(set_acl): Add: set a file's acl and S_ISUID, S_ISGID, and
	S_ISVTX to a defined value.  Fall back to fchmod/chmod when acls
	are unsupported.

	(uintmax_t) [defined uintmax_t]: Do not declare.
	(SIZE_MAX) [defined SIZE_MAX]: Do not define.

	know of any practical examples).

	leave errno alone.  Problem reported by Dmitry V. Levin.

2005-10-28  Paul Eggert  <eggert@cs.ucla.edu>

	and  Ulrich Drepper  <drepper@redhat.com>

	Import from libc.
	* obstack.c (print_and_abort) [defined _LIBC]: Use __fxprintf

	* getaddrinfo.h: Don't protect sys/types.h with HAVE_SYS_TYPES_H,
	we assume all systems have it, suggested by Jim Meyering
	<jim@meyering.net>.  Remove HAVE_SYS_SOCKET_H test too, to see if
	any systems lack sys/socket.h; mingw32 is known to lack it, but we
	don't support it yet anyway.  Also remove HAVE_NETDB_H test, for
	same reasons.

2005-10-04  Bruno Haible  <bruno@clisp.org>

2005-10-04  Simon Josefsson  <jas@extundo.com>

	Sync from coreutils.
	* .cppi-disable: Add getaddrinfo.h, getdelim.h, getline.h, getpass.c
	mbchar.h, mbuiter.h, strcase.h, strnlen.h, strnlen1.h.
	* .cvsignore: Add fts.h, search.h, t-fpending.
	* settime.c (settime): Fix { typo in previous patch.  Also, don't
	bother returning ENOSYS if settimeofday or stime fails; just let
	them return whatever errno they want to return.
	* utimens.c: Include unistd.h, for dup2.
	(futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if.
	(futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1.

2005-10-02  Jim Meyering  <jim@meyering.net>

	Sync from coreutils.
	* fts-cycle.c [HAVE_CONFIG_H]: Include <config.h>.

	Do not consume the fd unless successful.
	* openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
	* settime.c (settime): Move the HAVE_STIME block `up' into an #elif
	block, so that we don't even try to compile it if settimeofday is
	available.  This works around a compilation failure on OSF1 V5.1,
	due to stime requiring a `long int*' while tv_sec is `int'.

2005-09-30  Eric Blake  <ebb9@byu.net>  (tiny change)

	* getdelim.c (getdelim): Remove unused variables.

2005-10-01  Simon Josefsson  <jas@extundo.com>

	* getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.

	* getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef HAVE_CONFIG_H.

	for unsigned types.

2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>

	(futimens): Support having a null PATH if the file descriptor
	is nonnegative.

	* regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
	Remove.
	(__attribute): Define to empty unless GCC 3.1 or later.
	This works around a core dump on OpenBSD 3.4, which has GCC
	2.95.3, which dumps core when given __attribute__(()).  It also
	simplifies other tests, since we really don't want to bother with
	worrying about which ancient version of GCC supported what.
	Original problem reported by Yoann Vandoorselaere, with part of
	the fix suggested by Derek Price.

2005-09-24  Jim Meyering  <jim@meyering.net>

	* verify.h (verify_type__): Use `unsigned int' as the bitfield type
	so we can once again use a positive bitfield width of 1 -- now we
	don't have to explain why we were using a bitfield width of 2.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

	* getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
	Problem reported by Eric Blake.
	(getaddrinfo): Initialize se so that it's not garbage.
	Redo internal storage allocation so that it doesn't make unportable
	assumptions about alignment.
	Fix a memory leak.

	* utimens.c (futimens): Use futimesat if available.
	Prefer it to futimes since it doesn't have the futimes bug.

	* verify.h (GL_CONCAT0, GL_CONCAT): Remove.
	(verify): Don't use the __LINE__ trick, as it doesn't work in general.
	Instead, declare a function that returns a pointer to an array,
	and use verify_type__ to declare the size of the array.
	Problem and germ of a solution reported by Bruno Haible.
	(verify_type__): Use 2, not 1, for bitfield size, to avoid
	a warning with Irix 6.5 cc.  Problem reported by Bruno Haible.

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

	Sync from coreutils.

	stat-time.h.
	* argmatch.h: Include verify.h
	(ARGMATCH_VERIFY): Use verify rather than rolling our own.
	(ARGMATCH_ASSERT): Remove; unused.

	and stdio-safer.h.

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

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

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

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

	Improve quality of diagnostics on restore_cwd failure.
	* mkdir-p.h (make_dir): Remove.  All uses replaced by mkdir.
	(make_dir_parents): Last arg is now int * (for errno), not bool *.
	* mkdir-p.c (make_dir, make_dir_parents): Likewise.
	Rewrite "mkdir -p" algorithm to avoid the need for "stat"
	each time through the loop.  Do not diagnose restore_cwd failure;
	that is the caller's job (and perhaps the caller does not care).

	* mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
	(make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
	If the file already exists but is not a directory, don't bother
	to try to make its parents.
	Close potential file descriptor leak if we can't chdir("/") (!).
	Don't always return true if chdir($PWD) fails; return true only
	if the requested action was done successfully (except for the
	chdir($PWD)).
	Don't log final directory unless we actually made it.
	Refactor to avoid duplicate code to fix up permissions.
	Don't attempt to fix up parent permissions if chdir($PWD) fails.

	* strftime.c (my_strftime): Rewrite the previous change slightly,
	to make it a bit faster and (I hope) clearer.
	* strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
	Fix bug in formats like %2N.

	* verify.h: New file.

2005-09-22  Jim Meyering  <jim@meyering.net>

	Sync from coreutils.

	* backupfile.c: Use ARGMATCH_VERIFY, just in case.

	* posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
	the .tm_year member, since otherwise gcc-4.0 would now warn about
	tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.

	* quotearg.c (quotearg_n_options): Change code to be suboptimal, in
	order to avoid an unsuppressible warning from gcc on 64-bit systems.

	* getdate.y (get_date): Undo part of the 2005-04-04 change, so that
	the command "date -d'2005-03-27 +1 day'" succeeds once again, even
	when run in a time zone for which daylight savings time is in effect
	for the starting date.

	* mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
	stop us from restricting permissions of just-created absolute-named
	directories.
	* mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
	to restore initial working directory.
	* mkdir-p.c (make_dir_parents): New parameter: different_working_dir,
	to tell caller if/when we change the working directory and are
	unable to return to the initial one.
	* mkdir-p.h (make_dir_parents): Update prototype.
	* mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
	`return false'.  This fixes a bug introduced on 2004-07-30.

	* openat.c (fdopendir): Be sure to close the supplied
	file descriptor before returning.  This makes our replacement
	implementation a little closer to Solaris's, where fdopendir
	ties the file descriptor to the returned DIR* pointer.
	* openat.c (unlinkat): New function.
	* openat.h (unlinkat): Add prototype.
	* openat-die.c (openat_save_fail): Rename from openat_save_die.
	(openat_restore_fail): Rename from openat_restore_die.
	* openat.c, openat.h: Reflect s/_die/_fail/ renaming.

	Provide an alternative to exiting immediately upon save_cwd or
	restore_cwd failure.  Now, an application can arrange e.g.,
	to perform a longjump in that case.
	* openat.c: Include dirname.h.
	Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
	(rpl_openat, fdopendir, fstatat): Call openat_save_die
	and openat_restore_die rather than calling error directly.
	Don't include "error.h" or "exitfail.h"; they're no longer needed.

	* openat-die.c (openat_save_die, openat_restore_die): New file.
	* openat.h (openat_save_die, openat_restore_die): Declare and define.

	* strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
	size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
			    int utc, int nanoseconds);
	Background:
	date should not have to allocate a megabyte of virtual memory to
	handle a format argument like +%1048575T.  When implemented with
	strftime, it must allocate such a buffer, use strftime to fill it
	in, print it, then free it.
	With fprintftime, it simply prints everything and exits.
	With no need for memory allocation, that's one fewer way to fail.
	* strftime.c (my_strftime): Parse the colons of %:::z *after* the
	optional field width, not before, so we accept %9:z, not %:9z.
	(my_strftime): Be sure to use L_('x') for literals.

	* backupfile.c, canon-host.c, canonicalize.c, chown.c, cloexec.c:

	* unsetenv.c, userspec.c, xgethostname.c, xreadlink.c:
	Assume HAVE_UNISTD_H, i.e., include <unistd.h> unconditionally.

	* chown.c, cloexec.c, dup-safer.c, dup2.c, fsusage.c, getcwd.c:
	* getloadavg.c, mountlist.c, openat.h, save-cwd.c, tempname.c:
	Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally,
	and don't include <sys/file.h>).

2005-09-22  Eric Blake  <ebb9@byu.net>  (tiny change)

	Sync from coreutils.

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

2005-09-21  Bruno Haible  <bruno@clisp.org>

	* unicodeio.h (unicode_to_mb): New declaration.

2005-09-20  Derek Price  <derek@ximbiot.com>

	* getaddrinfo.c: Don't include <netdb.h> included from getaddrinfo.h.

	(MTIME_CMP, TIMESPEC_NS): Remove.  Now done by stat-time.h,
	in a different way.
	(timespec_cmp): New function.
	* utimecmp.c: Include stat-time.h.
	(SYSCALL_RESOLUTION): Depend on whether various struct stat

	(glob, globfree, glob_pattern_p): Now defined simply in terms of

	(build_collating_symbol):

	(bitset_contain): Return bool, not unsigned int with one bit on.
	All callers changed.
	* regexec.c (build_trtable): Don't assume bitset has no stricter

	problems when regoff_t is the same width as size_t.
	All callers changed.
	(re_search_2_stub): Check for overflow when adding the

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

	On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
	old glibc regex code mishandles strings longer than 2**31 bytes.
	This patch fixes this when the regex code is used in gnulib
	(i.e., outside glibc).

	This patch should not affect the use of the regex code inside
	glibc.  No doubt this problem also needs to be handled for glibc
	as well, but the result will be an incompatible change to the
	glibc ABI, and the old ABI will have to be supported too.  That
	can be the the subject for another patch.

	* regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro,
	governing whether the rest of this patch is active.  By default,
	the macro is disabled and the patch has no effect.
	(regoff_t) [defined _REGEX_LARGE_OFFSETS]: Define to off_t, not int.
	(__re_idx_t, __re_size_t, __re_long_size_t): New types.
	(struct re_pattern_buffer, re_search, re_search_2, re_match):

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

2005-08-26  Simon Josefsson  <jas@extundo.com>

	* getpass.c: Use _WIN32 instead of WIN32, suggested by Bruno
	Haible <bruno@clisp.org>.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

	* regexec.c (set_regs): Don't alloca with an unbounded size.

	alloca modernization/simplification for regex.
	* regex.c: Remove portability cruft for alloca.  This no longer
	needs to be at the start of the file, and can be moved into
	regex_internal.h and simplified.
	* regex_internal.h: Include <alloca.h>.
	(__libc_use_alloca) [!defined _LIBC]: New macro.
	* regexec.c (build_trtable): Remove "#ifdef _LIBC", since the code
	now works outside glibc.

2005-08-24  Simon Josefsson  <jas@extundo.com>

	* getpass.c: Add WIN32 implementation.  Conditionalize use of
	termios.h, tcgetattr, tcsetattr and __fsetlocking.  Remove some
	GLIBC specific code.

2005-08-25  Paul Eggert  <eggert@cs.ucla.edu>

	Make regex safe for g++.  This fixes one real bug (an "err"
	that should have been "*err").  g++ problem reported by
	Sam Steingold.
	* regex_internal.h (re_calloc): New macro, consistent with
	re_malloc etc.  All callers of calloc changed to use re_calloc.
	* regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,
	not int.  All callers changed.
	* regcomp.c (re_compile_fastmap_iter): Don't use alloca (mb_cur_max);

	(find_recover_state): Change "err" to "*err"; this fixes what
	appears to be a real bug.

	versus int.

2005-08-25  Jim Meyering  <jim@meyering.net>

	Otherwise, we'd lose LARGEFILE support in any file using
	e.g. "fcntl--.h"

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

	* regcomp.c (regerror): 2nd arg is 'restrict', as per POSIX.
	* regex.h (regerror): Likewise.

	* regex.c: Do not include <sys/types.h>, as POSIX no longer
	requires this.  (The code never needed it.)

	* regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
	All uses of recently-renamed identifiers changed to use the new,
	POSIX-compliant names.  The code will build and run just fine
	without these changes, but it's better to eat our own dog food
	and use the standard-conforming names.

	* regex.h: Fix a multitude of POSIX name space violations.
	These changes have an effect only for programs that define
	_POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
	do not change anything for programs compiled in the normal way.
	Also, there is no effect on the ABI.

	(_REGEX_SOURCE): New macro.
	Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
	defined and _GNU_SOURCE is not; this fixes a name space violation.

	Rename the following macros to obey POSIX requirements.
	The old names are still visible as macros if _REGEX_SOURCE is defined.
	(REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
	RE_BACKSLASH_ESCAPE_IN_LISTS.

	(REG_INTERVALS): renamed from RE_INTERVALS.
	(REG_LIMITED_OPS): renamed from RE_LIMITED_OPS.
	(REG_NEWLINE_ALT): renamed from RE_NEWLINE_ALT.
	(REG_NO_BK_BRACES): renamed from RE_NO_BK_BRACES.
	(REG_NO_BK_PARENS): renamed from RE_NO_BK_PARENS.
	(REG_NO_BK_REFS): renamed from RE_NO_BK_REFS.
	(REG_NO_BK_VBAR): renamed from RE_NO_BK_VBAR.
	(REG_NO_EMPTY_RANGES): renamed from RE_NO_EMPTY_RANGES.
	(REG_UNMATCHED_RIGHT_PAREN_ORD): renamed from
	RE_UNMATCHED_RIGHT_PAREN_ORD.
	(REG_NO_POSIX_BACKTRACKING): renamed from RE_NO_POSIX_BACKTRACKING.
	(REG_NO_GNU_OPS): renamed from RE_NO_GNU_OPS.
	(REG_DEBUG): renamed from RE_DEBUG.
	(REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
	(REG_IGNORE_CASE): renamed from RE_ICASE.  This renaming is a bit
	unusual, since we can't clash with the POSIX REG_ICASE.
	(REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
	(REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
	(REG_NO_SUB): renamed from RE_NO_SUB.
	(REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.
	(REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.
	(REG_SYNTAX_GNU_AWK): renamed from RE_SYNTAX_GNU_AWK.
	(REG_SYNTAX_POSIX_AWK): renamed from RE_SYNTAX_POSIX_AWK.
	(REG_SYNTAX_GREP): renamed from RE_SYNTAX_GREP.
	(REG_SYNTAX_EGREP): renamed from RE_SYNTAX_EGREP.
	(REG_SYNTAX_POSIX_EGREP): renamed from RE_SYNTAX_POSIX_EGREP.
	(REG_SYNTAX_ED): renamed from RE_SYNTAX_ED.
	(REG_SYNTAX_SED): renamed from RE_SYNTAX_SED.
	(_REG_SYNTAX_POSIX_COMMON): renamed from _RE_SYNTAX_POSIX_COMMON.
	(REG_SYNTAX_POSIX_BASIC): renamed from RE_SYNTAX_POSIX_BASIC.
	(REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from
	RE_SYNTAX_POSIX_MINIMAL_BASIC.
	(REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
	(REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
	RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
	(REG_DUP_MAX): renamed from RE_DUP_MAX.  No need to undef it.
	(REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
	(REG_REALLOCATE): Renamed from REGS_REALLOCATE.
	(REG_FIXED): Renamed from REGS_FIXED.
	(REG_NREGS): Renamed from RE_NREGS.

	(REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
	of other REG_* macros, since POSIX says the user is allowed to
	#undef these macros selectively.

	(reg_errcode_t): Update comment stating what other tables need
	to be consistent.

	Rename the following enum values to obey POSIX requirements.
	The old names are still visible as macros.
	(_REG_ENOSYS): Renamed from REG_ENOSYS.  Define even if _XOPEN_SOURCE
	is not defined, since GNU is supposed to be a superset of POSIX as
	much as possible, and since we want reg_errcode_t to be a signed
	type for implementation consistency.
	(_REG_NOERROR): Renamed from REG_NOERROR.
	(_REG_NOMATCH): Renamed from REG_NOMATCH.
	(_REG_BADPAT): Renamed from REG_BADPAT.
	(_REG_ECOLLATE): Renamed from REG_ECOLLATE.
	(_REG_ECTYPE): Renamed from REG_ECTYPE.

	(_REG_ESIZE): Renamed from REG_ESIZE.
	(_REG_ERPAREN): Renamed from REG_ERPAREN.
	(REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE):
	(REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
	(REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
	(REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.

	(_REG_RE_NAME, _REG_RM_NAME): New macros.
	(REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE.  All uses
	changed.  But support the old name if the new one is not defined
	and if _REGEX_SOURCE.

	Change the following member names in struct re_pattern_buffer.
	The old names are still supported if !_REGEX_SOURCE.
	The new names are always supported, regardless of _REGEX_SOURCE.
	(re_buffer): Renamed from buffer.
	(re_allocated): Renamed from allocated.
	(re_used): Renamed from used.
	(re_syntax): Renamed from syntax.
	(re_fastmap): Renamed from fastmap.

	(re_not_bol): Renamed from not_bol.
	(re_not_eol): Renamed from not_eol.
	(re_newline_anchor): Renamed from newline_anchor.

	Change the following member names in struct re_registers.
	The old names are still supported if !_REGEX_SOURCE.
	The new names are always supported, regardless of _REGEX_SOURCE.
	(rm_num_regs): Renamed from num_regs.
	(rm_start): Renamed from start.
	(rm_end): Renamed from end.

	(re_set_syntax, re_compile_pattern, re_compile_fastmap):
	(re_search, re_search_2, re_match, re_match_2, re_set_registers):
	Prepend __ to parameter names.

	Undo yesterday's changes.

	New private symbol, used to keep the enum signed in all cases.

	Fix problems reported by Sam Steingold in
	<http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00007.html>.
	* regexec.c (sift_states_bkref): Fix portability bug: the code
	assumed that reg_errcode_t is a signed type, which is not
	necessarily true if _XOPEN_SOURCE is not defined.
	* regex_internal.c (calc_state_hash): Put 'inline' before type, since
	some compilers warn about it otherwise.

	* regex_internal.c (re_acquire_state, re_acquire_state_context)
	[defined lint]: Suppress bogus uninitialized-variable warnings.

	* regcomp.c (duplicate_node): Return new index, not an error code,
	and let the caller return REG_ESPACE if out of space.  This
	removes an uninitialied-variable warning with GCC 4.0.1, and also
	avoids taking the address of a local variable.  All callers
	changed.

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

	* regexec.c (proceed_next_node): Redo local variables to
	avoid GCC shadowing warnings.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

	* regex_internal.c (re_string_realloc_buffers, re_node_set_insert):
	(re_node_set_insert_last, re_dfa_add_node):
	Rename local variables to avoid GCC shadowing warnings.

2005-08-18  Bruno Haible  <bruno@clisp.org>

	* strstr.c (strstr): Fix return value in multibyte case.
	* strcasestr.c (strcasestr): Likewise.

2005-08-17  Jim Meyering  <jim@meyering.net>

	Make the %s format (seconds since the epoch) work for a negative
	number and when used with a zero-padded field width, e.g. %015s.

	* strftime.c (my_strftime): Move the `do_number_sign_and_padding'
	label so that it precedes the code to set `digits'.  Otherwise,
	%0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
	print `00-22'.  Now, it prints `-0022', as it should.

2005-08-17  Paul Eggert  <eggert@cs.ucla.edu>

	* regex.h: Remove useless space-before-tab.  From coreutils.

2005-08-17  Bruno Haible  <bruno@clisp.org>

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

2005-08-17  Bruno Haible  <bruno@clisp.org>

	* strstr.h: Ignore HAVE_STRSTR, always declare the gnulib function.
	* strstr.c: Completely rewritten, with multibyte locale support.

2005-08-17  Bruno Haible  <bruno@clisp.org>

	* strcasecmp.c: Use mbuiter.h.

2005-08-17  Bruno Haible  <bruno@clisp.org>

	* mbuiter.h: New file.

2005-08-16  Bruno Haible  <bruno@clisp.org>

	* strcasecmp.c (struct mbiter_multi): Remove at_end field.
	(mbi_init): Update.
	(mbi_avail, mbi_advance): Let the iteration end before the terminating
	NUL byte, not after it.

2005-08-16  Bruno Haible  <bruno@clisp.org>

	* mbchar.h (mb_cmp, mb_casecmp): Order the invalid characters after
	the valid ones. Makes the comparison operations transitive:
	cmp (a, b) < 0 && cmp (b, c) < 0 ==> cmp (a, c) < 0.
	* strcasecmp.c (strcasecmp): Use mb_casecmp.

2005-08-16  Bruno Haible  <bruno@clisp.org>

	* strcase.h (strcasecmp): Add note in comments.
	* strncasecmp.c: Use code from strcasecmp.c.
	* strcasecmp.c: Use mbchar module. Define private mbiter variant.
	(strcasecmp): Work correctly in multibyte locales.

2005-08-16  Bruno Haible  <bruno@clisp.org>

	* strnlen1.h: New file.
	* strnlen1.c: New file.
