        * mutex.c (pthread_mutex_timedlock): New function suggested by
        Alexander Terekhov. The logic required to implement this
        properly came from Alexander, with some collaboration
        with Thomas Pfaff.
        (pthread_mutex_unlock): Wrap the waiters check and sema
        post in a critical section to prevent a race with
        pthread_mutex_timedlock.
        (ptw32_timed_semwait): New function;
        returns a special result if the absolute timeout parameter
        represents a time already passed when called; used by
        pthread_mutex_timedwait(). Have deliberately not reused
        the name "ptw32_sem_timedwait" because they are not the same
        routine.
        * condvar.c (ptw32_cond_timedwait): Use the new sem_timedwait()
        instead of ptw32_sem_timedwait(), which now has a different
        function. See previous.
        * implement.h: Remove prototype for ptw32_sem_timedwait.
        See next.
        (pthread_mutex_t_): Add critical section element for access
        to lock_idx during mutex post-timeout processing.
        * semaphore.h (sem_timedwait): See next.
        * semaphore.c (sem_timedwait): See next.
        * private.c (ptw32_sem_timedwait): Move to semaphore.c
        and rename as sem_timedwait().

        * sync.c (pthread_join): Was getting the exit code from the
        calling thread rather than the joined thread if
        defined(__MINGW32__) && !defined(__MSVCRT__).

        * pthread.h: Unless the build explicitly defines __CLEANUP_SEH,
        __CLEANUP_CXX, or __CLEANUP_C, then the build defaults to
        __CLEANUP_C style cleanup. This style uses setjmp/longjmp
        in the cancelation and thread exit implementations and therefore
        won't do stack unwinding if linked to applications that have it
        (e.g. C++ apps). This is currently consistent with most/all
        commercial Unix POSIX threads implementations.

        * spin.c (pthread_spin_init): Edit renamed function call.
        * nonportable.c (pthread_num_processors_np): New.
        (pthread_getprocessors_np): Renamed to ptw32_getprocessors
        and moved to private.c.
        * private.c (pthread_getprocessors): Moved here from
        nonportable.c.
        * pthread.def (pthread_getprocessors_np): Removed
        from export list.

        * rwlock.c (pthread_rwlockattr_init): New.
        (pthread_rwlockattr_destroy): New.
        (pthread_rwlockattr_getpshared): New.
        (pthread_rwlockattr_setpshared): New.
