* 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.

 1. Under MS VC++ (only tested with version 6.0), a term_func

-   set via the standard C++ set_terminate() function is not called

-   for some reason. The code in private.c ptw32_threadStart()

-   retrieves and calls the user supplied terminate routine, which

-   works as expected under MinGW32 g++, but doesn't run under

-   MS VC++ 6.0, presumably because set_terminate() returns NULL.

+   set via the standard C++ set_terminate() function is not called.

+

+   Notes from the MSVC++ manual:

+         1) A term_func() should call exit(), otherwise

+            abort() will be called on return to the caller.

+            A call to abort() raises SIGABRT and the default signal handler

+            for all signals terminates the calling program with

+            exit code 3.

+         2) A term_func() must not throw an exception. Therefore

+            term_func() should not call pthread_exit(), which

+            works by throwing an exception (pthreadVCE or pthreadVSE)

+            or by calling longjmp (pthreadVC).

+

+   Workaround: avoid using pthread_exit() in C++ applications. Exit

+   threads by dropping through the end of the thread routine.
