i wasn't able to find any different HINSTANCE definition than void * but it
could be that i missed the right one. it's really hard to find something
like that on windows. maybe i will look for some tool which allows regular
expressions for searching. i will also try to find out if i can do something
like -M with the visual c++ compiler. thanks!

yes, i am using cython. i think i read somewhere that cython questions can
or should also be asked on the pyrex list but i will look for the cython
list next time. sorry!
