And now I have the compilation workaround on my disk, but there are
inexplicable errors linking to Python-22.lib: it's having no problem
linking to functions, but data objects like PyList_Type aare choking it.
Can you build and link a simple "C" extension module with this compiler? It
seems like something is very wrong here!
