Update.
2003-03-11 Ulrich Drepper <drepper@redhat.com>
* sysdeps/unix/sysv/linux/i386/i486/pthread_cond_wait.S
(__condvar_cleanup): Wake up all waiters in case we got signaled
after being woken up but before disabling asynchronous
cancellation.
* sysdeps/pthread/pthread_cond_wait.c (__condvar_cleanup): Likewise.
* sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S
(__condvar_cleanup): Likewise.
* init.c (__NR_set_tid_address): If already defined, don't redefine.
Make it an error if architecture has no #if case. Add x86-64.
* sysdeps/unix/sysv/linux/x86_64/Makefile: Add flags for
pt-initfini.s generation.
* sysdeps/x86_64/tls.h: Include <asm/prctl.h>.
(TLS_INIT_TP): Fix typo.
