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).
