win32/include/winapi changes from https://github.com/run4flat/tinycc.git

        just for testing. Is it needed? I'm not a MSYS citizen.

        run4flat is a tcc fork by David Mertens that knows how to work with
        multiple symbol tables. Excelent work. A good descriptions of the
        tcc internals inside a code comments.
