        * implement.h: Add #include <pthread.h>.
        Change sem_t to _pthread_sem_t.
        Various patches by Kevin Ruland <Kevin.Ruland@anheuser-busch.com>
        * signal.c (pthread_sigmask): Add and modify casts.
        Reverse LHS/RHS bitwise assignments.
        * pthread.h: Remove #include <semaphore.h>.
        (_PTHREAD_ATTR_VALID): Add cast.
        (struct pthread_t_): Add sigmask element.
        * dll.c: Add "extern C" for DLLMain.
        (DllMain): Add cast.
        * create.c (pthread_create): Set sigmask in thread.
        * condvar.c: Remove #include. Change sem_* to _pthread_sem_*.
        * attr.c: Changed #include.
        * Makefile.in: Additional targets and changes to build the library
        as a DLL.
Fri Jan 29 11:56:28 1999  Ross Johnson  <rpj@swan.canberra.edu.au>
        * Makefile.in (OBJS): Add semaphore.o to list.
        * semaphore.c (_pthread_sem_timedwait): Move from private.c.
        Rename sem_* to _pthread_sem_*.
        * pthread.h (pthread_cond_t): Change type of sem_t.
        _POSIX_SEMAPHORES no longer defined.
        * semaphore.h: Contents moved to implement.h.
        Removed from source tree.
        * implement.h: Add semaphore function prototypes and ename all
        functions to prepend '_pthread_'. They are
        now private to the pthreads-win32 implementation.
        * private.c: Change #warning.
        Move _pthread_sem_timedwait() to semaphore.c.
        * cleanup.c: Change #warning.
        * misc.c: Remove #include <errno.h>
        * pthread.def: Cleanup CVS merge conflicts.
        * global.c: Ditto.
        * ChangeLog: Ditto.
        * cleanup.c: Ditto.
