Tue Aug 27 17:45:21 1996  Ulrich Drepper  <drepper@cygnus.com>

	* Makerules: Add some test for correct version of GNU Make.

	* io/fcntl.h: Undo change from Mon Aug 26 22:22:17 1996.
	* sysdeps/unix/sysv/linux/fcntlbits.h: Place macros here instead.

	* sysdeps/generic/dl-sysdep.c: Initialize break address to
	avoid overwriting last page (OK, Roland).

Tue Aug 27 16:20:37 1996  Ulrich Drepper  <drepper@cygnus.com>

	* resolv/resolv.h: Update from BIND-4.9.5-T3A.
	* resolv/arpa/nameser.h: Likewise.
	* resolv/res_init.c: Likewise.
	* resolv/res_debug.c: Likewise.
	* resolv/res_mkquery.c: Likewise.

Tue Aug 27 15:47:04 1996  Ulrich Drepper  <drepper@cygnus.com>

	* elf/dl-error.c (catch): Define errstring element not as const.
	(_dl_catch_error): ERRSTRING argument is not const pointer.
	Initialize *ERRSTRING and *OBJNAME separately.
	* elf/link.h: Change prototype for `_dl_catch_error'.

	* elf/dl-load.c (_dl_map_object): Use separate variable for
	copied NAME to avoid `const' warning.

	* elf/dlerror.c: Make `last_errstring' variable not const pointer.

	* elf/rtld.c: Implement reading of /etc/ld.so.preload.  This
	provides preloading even for SUID binaries.
	Add some more casts to avoid signed<->unsigned warnings.

Tue Aug 27 15:40:28 1996  NIIBE Yutaka  <gniibe@mri.co.jp>

	* posix/sys/types.h: Define loff_t.
	* sysdeps/unix/sysv/linux/gnu/types.h: Define __loff_t.

Mon Aug 26 16:31:33 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* sysdeps/mach/hurd/setitimer.c (setitimer_locked): Tolerate NEW
	being null; in that case don't touch the timer at all (but do
	return something in OLD if necessary).

Mon Aug 26 13:35:16 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* sysdeps/mach/hurd/i386/init-first.c (__libc_multiple_libcs): New
 	variable.
	* sysdeps/i386/init-first.c: Likewise.
	* sysdeps/stub/init-first.c: Likewise.
