Python 2.3.3 (but not 2.3.2 or earlier) should have displayed a warning
when it finds these incomplete registry entries:

     self.warn("It seems you have Visual Studio 6 installed, "
               "but the expected registry settings are not present.\n"
               "You must at least run the Visual Studio GUI once "
               "so that these entries are created.")

distutils doesn't pass -Wall to the MSVC compiler.  A bug in the setup script?
