Tue Oct 22 21:38:21 1996  Ulrich Drepper  <drepper@cygnus.com>

	* version.h: Bump version number to 1.97.

	* features.h: Undo change of Sun Oct 20 22:19:58 1996.
	Include libc-version.h.
	* features.h.in: Removed.
	* Makefile: Change rules to generate libc-version.h instead of
	features.h.

	* malloc/free.c: Add cast to prevent warning.
	* malloc/malloc-walk.c: Likewise.
	* malloc/ralloc.c: Likewise.
	* malloc/realloc.c: Likewise.

	* grp/fgetgrent_r.c: Accept empty numeric field if name start with +
	or -.
	* pwd/fgetpwent_r.c: Likewise.
	* nss/nss_files/files-grp.c: Don't accept entries with names starting

Mon Oct 21 22:52:16 1996  NIIBE Yutaka  <gniibe@mri.co.jp>

	* elf/dl-minimal.c: Don't define `dgettext' replacement but
	`dcgettext'.  When optimizing the macros in <libintl.h> define
	`dgettext' as a macro and so this function will never be called.

Mon Oct 21 15:41:59 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/i386/time.S: Add PSEUDO_END to get
 	__syscall_error defined..

Sat Oct 19 12:27:50 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/m68k/mmap.S: Fix braino: CALL_MCOUNT is
	already included in the ENTRY macro.  Remove SYSCALL_ERROR_HANDLER
	now provided by PSEUDO_END.
	* sysdeps/unix/sysv/linux/m68k/sigreturn.S: Likewise.

Sat Oct 19 12:13:24 1996  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sysdeps/unix/sysv/linux/syscalls.list (getresuid, setresuid):
	Set caller to EXTRA.

	O_SHLOCK.

Tue Oct 15 14:37:40 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>
