        * buildlib.bat: Fix args to CL when building the .DLL
        * cleanup.c (_pthread_destructor_run_all): Fix TSD key management.
        This is a tidy-up before TSD and Thread management is completely
        replaced by John Bossom's much more elegant code.
        * tsd.c (pthread_key_create): Fix TSD key management.
        * global.c (_pthread_key_virgin_next): Initialise.
        * build.bat: New DOS script to compile and link a pthreads app
        using Microsoft's CL compiler linker.
        * buildlib.bat: New DOS script to compile all the object files
        and create pthread.lib and pthread.dll using Microsoft's CL
        compiler linker.
