You can probably just define pFPyEval_EvalCode as taking a PyObject * 
(but I'm not sure where you are getting a declaration of PyObject * from)

Are you sure you have the calling convention correct on those function 
pointer decls?

py2exe takes the same basic approach as you and might be worth copying 
its declarations for the function pointers?
