Subject:         * 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.
