Hi,

I take it you are using an official Python binary?
That's built with MS c-compiler.

The key here is to observe how the linker looks for "_imp__PyType_Type",
while the import library provided by the official distribution
lists this as "__imp__PyType_Type".
If I remeber correctly, that's a known mingw issue when building
extensions for an MS-built Python.
I can't recall more details, but you'll find plenty of stuff about this
on the web.

Best Regards,
Mathias
