	Suggested by Philip Blundell <pjb27@cam.ac.uk>.

1997-02-01 12:34  Ulrich Drepper  <drepper@cygnus.com>

	* time/strftime.c: Define _strftime_copytm without protecting arguments
	which breaks the definition.

1997-02-01 03:31  Thorsten Kukuk  <kukuk@weber.uni-paderborn.de>

	* nis/rpcsvc/yp_prot.h: Move definition of yppushresp_xfr after

1997-01-31  Paul Eggert  <eggert@twinsun.com>

	* time/mktime.c (HAVE_LIMITS_H, HAVE_LOCALTIME_R, STDC_HEADERS):
	Define if _LIBC is defined.
	<limits.h>: Include if HAVE_LIMITS_H instead of if
	__STDC__ || __GNU_LIBRARY__ || STDC_HEADERS.
	<stdlib.h>: Similarly, include if STDC_HEADERS.
	(localtime_r): Redo #ifdef to make it clear that glibc has
	localtime_r now.

1997-02-29 20:08  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* sunrpc/Makefile ($(objpfx)rpcsvc/%.h, $(objpfx)x%.c): Use stamp
	file to avoid unnecessary recompilation.

1997-01-29 19:33  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* Makefile: Set install-others, not install_others.
	(before-compile): Use += to preserve previous value.
	($(inst_includedir)/gnu/lib-names.h): Remove obsolete comment and
	fix dependency name.
	($(objpfx)lib-names.h): Remove rule.
	* Makeconfig ($(common-objpfx)gnu/lib-names.h): Generate it here,
	with correct name, using an intermediate stamp file.
	(common-generated): Add gnu/lib-names.h.
	(before-compile): Add $(common-objpfx)gnu/lib-names.h.

1997-01-30 18:29  Richard Henderson  <richard@atheist.tamu.edu>

	* malloc/malloc.c (MAGICBYTE): Use cast to size_t instead of unsigned
	to prevent warnings on 64 bit systems.
	Reported by Paul Wouters <paul@xtdnet.nl>.

	* sysdeps/alpha/dl-machine.h: Revert check for broken gas.  By default
	we assume it works.
