Update.
2003-12-11 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/i386/lowlevellock.h (lll_futex_wait):
Assume parameter is a pointer.
(lll_futex_wake): Likewise.
Reported by Boris Hu.
* sysdeps/unix/sysv/linux/unregister-atfork.c
(__unregister_atfork): Pass pointer to refcntr to lll_futex_wait.
* sysdeps/unix/sysv/linux/sem_wait.c (__new_sem_wait): Simplify a bit.
