Sorry, bad patch...

This should be:

    scripts = ["win32_postinstall.py"]
    # put the mod_python.so file in the Python root ...
    # win32_postinstall.py will pick it up from there...
    data_files = [("", [(os.path.join(getmp_srcdir(), 'Release', 

But I'll fix it all up properly when I combine everything...

I also suspect our method of detecting compiling on Windows is a bit 
strange ... it only adds the scripts in if we're building a windows 
But this is impossible from Unix anyway (since you can't compile the C 
extensions...) so maybe we should just detect the current platform
