Fri Sep 13 04:33:08 1996  Ulrich Drepper  <drepper@cygnus.com>

	* sched.h: New file.  helper to access posix/sched.h.
	* posix/sched.h: Change `sched_params' to `sched_param' to follow
	POSIX.4.

Thu Sep 12 20:12:40 1996  Ulrich Drepper  <drepper@cygnus.com>

	* db/makedb.c (usage): Print bug report address separately to
	ease translators task.
	* catgets/gencat.c (usage): Likewise.
	* locale/locale.c (usage): Likewise.
	* locale/localedef.c (usage): Likewise.

1996-09-12  Paul Eggert  <eggert@twinsun.com>

	* time/strftime.c (my_localtime_r): Define if ! HAVE_LOCALTIME_R,
	and #define localtime_r to it.	If _LIBC, use __localtime_r instead.
	(my_gmtime_r): Similar, except it's not needed if ! HAVE_TM_GMTOFF.

Thu Sep 12 14:03:29 1996  Ulrich Drepper  <drepper@cygnus.com>

	* crypt/Makefile: Include Makeconfig and add crypt object dir to
 	rpath-link so that running the check finds the new library.
	* crypt/cert.c: provide correct prototypes to prevent warnings.
	Reported by Andreas Jaeger.

	* sysdeps/mach/hurd/Makefile (rpath-link): Don't use += because
	old and new value must be glued using `:'.
	Reported by Marcus Daniels.
