        * sched.c (sched.h): Include.
        * sched.h: New file for POSIX 1b scheduling.
        * pthread.h: Move opaque structures to implement.h; move sched_*
        prototypes out and into sched.h.
        * implement.h: Add opaque structures from pthread.h.
        * sched.c (sched_yield): New function.
        * condvar.c (_pthread_sem_*): Rename to sem_*; except for
        _pthread_sem_timedwait which is an private function.
Sat Apr  3 23:28:00 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * Makefile.in (OBJS): Add errno.o.
Fri Apr  2 11:08:50 1999  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>
        * implement.h (_pthread_sem_*): Remove prototypes now defined in
        semaphore.h.
        * pthread.h (sempahore.h): Include.
        * semaphore.h: New file for POSIX 1b semaphores.
        * pthread.h (_pthread_sem_t): Change to sem_t.
        * semaphore.c (_pthread_sem_*): Change to sem_*; these functions
        will be exported from the library; set errno on error.

        (_pthread_sem_timedwait): Moved to private.c.
        * private.c (_pthread_sem_timedwait): Moved from semaphore.c;
