Update.

2003-07-08  Jakub Jelinek  <jakub@redhat.com>

	* pthreadP.h (__pthread_unwind_next, __pthread_register_cancel,
	__pthread_unregister_cancel): Add prototypes and hidden_proto.
	* unwind.c (__pthread_unwind_next): Add hidden_def.
	* cleanup.c (__pthread_register_cancel, __pthread_unregister_cancel):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/i486/sem_wait.S (__new_sem_wait):
	Use HIDDEN_JUMPTARGET to jump to __pthread_unwind.
	* sysdeps/unix/sysv/linux/i386/i486/sem_timedwait.S (sem_timedwait):
	Likewise.
	* sysdeps/unix/sysv/linux/x86_64/sem_wait.S (sem_wait): Likewise.
	* sysdeps/unix/sysv/linux/x86_64/sem_timedwait.S (sem_timedwait):
	Likewise.
	* sysdeps/unix/sysv/linux/i386/pthread_once.S (__pthread_once): Use
	HIDDEN_JUMPTARGET to call __pthread_register_cancel,
	__pthread_unregister_cancel and __pthread_unwind_next.
