Update.

2000-07-18 Kaz Kylheku <kaz@ashi.footprints.net>

	* spinlock.c (__pthread_alt_lock, __pthread_alt_timedlock): Fixed
	bug whereby thr field of waitnode structure would not be correctly
	set unless a null self pointer is passed to the functions.
	Eliminated redundant calls to thread_self().
