iirc, the DL_EXPORT stuff is there to make sure
everything is exported from the python core dll.

if you're building a dynamic extension, and have
trouble exporting the init function, you might do
something like this instead:

void
#ifdef WIN32
__declspec(dllexport)
#endif
initsgmlop()
{
    /* Patch object type */
    FastSGMLParser_Type.ob_type = &PyType_Type;

    Py_InitModule("sgmlop", _functions);
}

(make sure WIN32 is defined when you compile the
module).

also note that you may have to initialize your
type descriptors (if any) in the init function
under Windows; for more info, see:
