Hm.  This works with GCC on Unix, and also works with MSVC on Windows.
But if you feel that GCC on Windows is an important target, can you
please check in a fix?  It's a fine line, initializing structures with
addresses defined in different files often doesn't seem to work on
Windows.  MSVC has this problem only for the address of external
data, I believe -- over the years we've grown a whole set of ways to
deal with the fact that you can't initialize the ob_type field of a
type struct with &PyType_Type on Windows...
