Update.

2003-08-13  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/i386/syscalls.list: Add time syscall.

	* elf/Makefile: Use LC_ALL=C in a few cases where we call external
	text processing tools.

	* sysdeps/pthread/aio_misc.h (struct waitlist): Don't add caller_pid
	element unless BROKEN_THREAD_SIGNALS is defined.
	(struct requestlist): Likewise.
	* sysdeps/pthread/aio_misc.c (__aio_enqueue_request): Don't fill in
	caller_pid of new request unless BROKEN_THREAD_SIGNALS is defined.
	* sysdeps/pthread/aio_suspend.c (aio_suspend): Likewise.
	* sysdeps/pthread/aio_notify.c (__aio_notify_only): Remove caller_pid
	parameter unless BROKEN_THREAD_SIGNALS is defined.  Adjust callers.
	Pass current PID to __aio_sigqueue.
	* sysdeps/pthread/lio_listio.c (lio_listio): Adjust __aio_notify_only
	call.  Don't initialize caller_pid field of waitlist element.
