1997-11-04  Ulrich Drepper  <drepper@cygnus.com>

	* manual/filesys.texi: Correct description of return value for
	readdir_r.
	* sysdeps/unix/readdir_r.c (__readdir_r): Return value of errno
	not -1 in error case.
	* sysdeps/generic/readdir_r.c (__readdir_r): Return ENOSYS not -1.
	Reported by Jim Meyering <meyering@eng.ascend.com>.

1997-11-02  Paul Eggert  <eggert@twinsun.com>

	* strftime.c: Use host's underlying strftime to access
	locale-specific info.  This is useful e.g. when building GNU
	Emacs under Solaris 2.6.
	(weekday_name, month_name): Omit if HAVE_STRFTIME.
	(my_strftime): New macro, which names the strftime function that
	this source file produces.
	(strftime): #undef if emacs is defined; this works around Emacs 20.2's
	method of compiling with -Dstrftime=emacs_strftime.
	Also, declare as a function returning size_t, for similar reasons.
	(my_strftime): If HAVE_STRFTIME, use underlying strftime to handle
	locale-dependent formats like %a and %Ec.

1997-11-02  Paul Eggert  <eggert@twinsun.com>

	* strftime.c (memcpy_lowcase, memcpy_uppcase, strftime):
	Ensure that args to islower and isupper are valid unsigned
	chars, even if char is signed.

1997-11-04  Ulrich Drepper  <drepper@cygnus.com>

	* assert/Makefile (headers): Add assert.h, necessary after patch
	to Makefiles.
	* ctype/Makefile (headers): Likewise.
	* pwd/Makefile (headers): Likewise.
	* grp/Makefile (headers): Likewise.
	Patch by NIIBE Yutaka <gniibe@mri.co.jp>.

1997-11-04 03:08  Ulrich Drepper  <drepper@cygnus.com>

	* glibcbug.in: Add information about configured target.
	Patch by Zack Weinberg <zack@rabi.phys.columbia.edu>.

	* elf/dl-lookup.c (_dl_lookup_versioned_symbol): Be prepared for
	empty string as `reference_name' parameter.
	* elf/rtld.c: Don't set real program name in l_name of main object.

	* manual/creature.texi: Apply Paul Eggert's patch for better
	_POSIX_C_SOURCE description.

	* stdlib/strfmon.c: Fix numerous bugs in formatting.

	* time/strptime.c [%Y]: Treat all years, not only those which fit
	in time_t.
	[%Oy]: Really store value.
	Patches by Paul Eggert.

	* wcsmbs/wchar.h: Fix documentation bugs.  Declare wcsdup only
	is __USE_GNU.

1997-11-03 02:48  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/bits/errno.h: Remove all error definitions.  This
	is only meant as a stub.

1997-10-31  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* sysdeps/standalone/bits/errno.h: Copied from
	sysdeps/generic/bits/errno.h and added all know error codes that
	are used in glibc.

1997-11-03 02:23  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/make_siglist.c: Add comment to clarify use and
	make sure the correct _NSIG value is used.
	Patch by Klaus Espenlaub <kespenla@student.informatik.uni-ulm.de>.

1997-11-03 00:20  Ulrich Drepper  <drepper@cygnus.com>

	* intl/localealias.c (read_alias_file): Correct handling of line
	reader which sometimes skipped complete lines (PR 205).
	Optimize a bit by using mempcpy.

1997-11-02 16:59  Philipp Thomas  <kthomas@gwdg.de>

	* intl/localealias.c (read_alias_file): Correctly set map[].value
	instead of overwriting map[].alias

1997-11-02 15:32  Ulrich Drepper  <drepper@cygnus.com>

	* libc.map: Add _IO_flockfile and _IO_funlockfile.
	Suggested by H.J. Lu <hjl@lucon.org>.

1997-11-02 15:17  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-error.c (_dl_signal_error): Use _strerror_internal instead
	of strerror.
	* assert/assert-perr.c: Use _strerror_internal directly instead of
	__strerror_r.
	Suggested by Joe Keane <jgk@jgk.org>.

1997-11-01 16:46  Zack Weinberg  <zack@rabi.phys.columbia.edu>

	* configure.in: Check for gcc-2.7.2 -pipe bug and hack around it
	(PR 245).

1997-11-01  Paul Eggert  <eggert@twinsun.com>

	* time/strptime.c (strptime_internal): Fix bug: %Oy forgot to
	assign tm_year.  Do not restrict %Y to years less than 2037 even
	on 32-bit time_t hosts, as strptime returns an int tm_year, not a
	time_t, and it's possible for programs to use the year without
	having to use time_t.

	non-directories in the list (PR 203).
