i'm having problems w/ vc6 and python..
i'm trying to compile examples\getting_started2.cpp 
and it compiles , but i get like 23 warnings, and when
i throw the getting_started2.dll into the python
syspath (specifically in
C:\Python22\Lib\site-packages\ ) 
i get errors form the example\test_getting_started2.py

what am i doing wrong? :/

here are the warnings :
