Merge changes from hurd-l4 fork. * Makefile (SRCS): Add pt-startup.c and pt-mutex-transfer-np.c. (sysdeps_headers): Add pthread-np.h. 2008-08-12 Neal H. Walfield <neal@gnu.org> * sysdeps/generic/bits/pthread-np.h: New file. 2008-08-12 Neal H. Walfield <neal@gnu.org> * sysdeps/generic/pt-startup.c: New file. 2008-08-12 Neal H. Walfield <neal@gnu.org> * sysdeps/generic/bits/mutex.h (__PTHREAD_RECURSIVE_MUTEX_INITIALIZER): Define. (__PTHREAD_MUTEX_RECURSIVE_INITIALIZER): Don't define. * include/pthread/pthread.h (PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP) [__USE_GNU]: Define. (PTHREAD_MUTEX_RECURSIVE_INITIALIZER_NP): Don't define. 2008-08-12 Neal H. Walfield <neal@gnu.org> * include/pthread/pthread.h: Include <sys/cdefs.h>. (__extern_inline): If not defined, define appropriately. 2008-06-01 Neal H.

Walfield <neal@gnu.org> * include/pthread/pthread.h: Include <bits/pthread-np.h>. 2008-03-01 Neal H. Walfield <neal@gnu.org> * sysdeps/generic/pt-mutex-transfer-np.c: New file. * pthread/pt-self.c (pthread_self): Assert that SELF is not NULL. 2007-12-23 Neal H. Walfield <neal@gnu.org> * pthread/pt-join.c (pthread_join): Cast argument to pthread_cleanup_push to avoid warning. 2007-11-23 Neal H.
