Update.
2003-04-04 Ulrich Drepper <drepper@redhat.com> * sysdeps/pthread/createthread.c (create_thread): Add some more comments explaining when to set multiple_threads and when not. * pthreadP.h: Define THREAD_ATOMIC_CMPXCHG_VAL and THREAD_ATOMIC_BIT_SET if not already defined. * sysdeps/i386/tls.h: Define THREAD_ATOMIC_CMPXCHG_VAL and THREAD_ATOMIC_BIT_SET: * sysdeps/x86_64/tls.h: Likewise. * cleanup_defer.c (_pthread_cleanup_push_defer): Rewrite to use THREAD_ATOMIC_CMPXCHG_VAL. (_pthread_cleanup_pop_restore): Likewise. * cancellation.c (__pthread_enable_asynccancel): Likewise. (__pthread_enable_asynccancel_2): Likewise. (__pthread_disable_asynccancel): Likewise. * libc-cancellation.c (__libc_enable_asynccancel): Likewise. (__libc_disable_asynccancel): Likewise. * init.c (sigcancel_handler): Likewise. * pthread_setcancelstate.c (__pthread_setcancelstate): Likewise. * pthread_setcanceltype.c (__pthread_setcanceltype): Likewise.
