Update.
2002-12-11  Ulrich Drepper  <drepper@redhat.com>

	* malloc/thread-m.h: Remove thread_id type and MUTEX_INITIALIZER
	definitions.  Not needed.
	[_LIBC]: Use definitions from libc-lock.h instead of referencing
	pthread routines directly.
	* malloc/arena.c (ptmalloc_unlock_all2): Don't add (void) to
	mutex_init calls.
	(arena_get2): Don't look at return value of mutex_lock.
