Update.

1998-03-05  Ulrich Drepper  <drepper@cygnus.com>

	* elf/rtld.c: Speed up processing of environment variables.  Do
	only one run on the environment by avoiding to call getenv.
	* sysdeps/generic/dl-sysdep.c (_dl_next_ld_env_entry): New
	function.  Used by patch above.

1998-03-05 10:25  Ulrich Drepper  <drepper@cygnus.com>

	* nss/getXXbyYY_r.c: Don't try to contact nscd every time when it
	failed.  Only do this every NSS_NSCD_RETRY times.
	* nss/nsswitch.c: Define __nss_nscd_not_available, used by above
	change.
	* nscd/nscd_getgr_r.c (__nscd_getgr_r): Return 2 if contacting the
	daemon failed.
	* nscd/nscd_getpw_r.c (__nscd_getpw_r): Likewise.

1998-03-05  Ulrich Drepper  <drepper@cygnus.com>

	* nss/nsswitch.c (nss_lookup_function): Don't modify errno if NSS
	module cannot be found.  Reported by Andreas Jaeger.

1998-03-05 11:40  Franz Sirl <Franz.Sirl-kernel@lauterbach.com>

	* nscd/nscd_getgr_r.c: Change char to int to avoid compiler warning
	on platforms which default to unsigned chars.
	* nscd/nscd_getpw_r.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/sysdep.h: Undefine L before
	defining it.

1998-03-05  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* elf/Makefile (install-bin): Change = to += for sprof to install
	ldd also.
