Update.
2001-11-30 Andreas Schwab <schwab@suse.de>
* pthread.c (pthread_handle_sigcancel) [THREAD_SELF]: Double check
that self is the manager thread, and initialize the thread
register if not.
(thread_self_stack) [THREAD_SELF]: New function to find self via
stack pointer.
* manager.c (pthread_handle_create): Don't block cancel signal any
more.
(THREAD_GETMEM_NC):
