Update.

2003-05-30  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/unix/sysv/linux/ia64/lowlevellock.h
	(__lll_mutex_cond_lock): Add one to value parameter of
	__lll_lock_wait to reflect reality in the futex syscall.
	* sysdeps/unix/sysv/linux/powerpc/lowlevellock.h
	(lll_mutex_cond_lock): Likewise.
