/usr/include/w32api/windef.h:#define CALLBACK __stdcall

So it should just work, both are the same calling convention,
CALLBACK is not using cdecl.

I'll check if I see something wrong how callbacks (T_CODE)
are handled in API.xs
But I rather believe the user callback sub is just wrong.
You have to debug into the perl-side of the callback.
