1999-10-17 Ross Johnson <rpj@ixobrychus.canberra.edu.au>

        * rwlock.c (pthread_rwlock_destroy): Add cast to remove compile
        warning.

        * condvar.c (pthread_cond_broadcast): Only release semaphores
        if there are waiting threads.

1999-10-15  Ross Johnson  <rpj@ixobrychus.canberra.edu.au>

        * condvar.c (cond_wait_cleanup): New static cleanup handler for
        cond_timedwait;
        (cond_timedwait): pthread_cleanup_push args changed;
        canceling a thread while it's in pthread_cond_wait
        will now decrement the waiters count and cleanup if it's the
        last waiter.
        - Lorin Hochstein <lmh@xiphos.ca> and
          Peter Slacik <Peter.Slacik@tatramed.sk>;
        the last waiter will now reset the CV's wasBroadcast flag
        - Graham Dumpleton <Graham.Dumpleton@ra.pad.otc.telstra.com.au>.
