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.

 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.
