        * dll.c (dllMain): Remove 2000-07-21 change - problem
        appears to be in pthread_create().

2000-07-21  Ross Johnson  <rpj@setup1.ise.canberra.edu.au>

        * create.c (pthread_create): Set threadH to 0 (zero)
        everywhere. Some assignments were using NULL. Maybe
        it should be NULL everywhere - need to check. (I know
        they are nearly always the same thing - but not by
        definition.)

        * dll.c: Include resource leakage work-around. This is a
        partial FIXME which doesn't stop all leakage. The real
        problem needs to be found and fixed.
        - "David Baggett" <dmb@itasoftware.com>

        * misc.c (pthread_self): Try to catch NULL thread handles
        at the point where they might be generated, even though
        they should always be valid at this point.

        * tsd.c (pthread_setspecific): return an error value if
        pthread_self() returns NULL.

        * sync.c (pthread_join): return an error value if
        pthread_self() returns NULL.

        * signal.c (pthread_sigmask): return an error value if
        pthread_self() returns NULL.
