* internals.h (struct _pthread_descr_struct): Reorganization.
Allocate room for 16 pointers at head of the structure for future
thread-local data handling. Move p_self member in this area.
* manager.c (pthread_handle_create): Adjust use of p_self.
* sysdeps/i386/useldt.h (THREAD_SELF): Likewise.
* pthread.c (__pthread_initial_thread): Adjust initialization.
(__pthread_manager_thread): Likewise.
2000-04-29 Bruno Haible <haible@clisp.cons.org>
* join.c (pthread_exit): Use THREAD_GETMEM_NC instead of THREAD_GETMEM
for eventmask larger than 1 word.
