* errno.c: Compiler directive was incorrectly including code.

        * pthread.h: Conditionally added some #defines from config.h
        needed when not building the library. e.g. NEED_ERRNO, NEED_SEM.
        (PTW32_DLLPORT): Now only defined if _DLL defined.
        (_errno): Compiler directive was incorrectly including prototype.
        * sched.h: Conditionally added some #defines from config.h
        needed when not building the library.
        * semaphore.h: Replace an instance of NEED_SEM that should
        have been NEED_ERRNO. This change currently has nil effect.

        * GNUmakefile: Correct some recent changes.

        * Makefile: Add rule to generate pre-processor output.
