[Python-Dev] Is __declspec(dllexport) really needed on Windows?

That's wrong. You should be using DL_EXPORT instead, which will do the
right thing no matter which platform you're on: on Windows, it will
expand to __declspec(dllexport), iff you're compiling an extension
module (in contrast to compiling the Python core). I believe that on
Unix, it will expand to an empty string :-)

You also don't need any #ifdefs for win32 for setting ob_type, just set
them _only_ in your init function and leave them as NULL in the
declarations.
