Where does math.h get invoked?  Does that come from including python.h? 
Are you embedding Python into your app, or is your app an add-on to Python?

The key issue with mixing compilers is getting the run-time libraries
mixed up.  As long as your application links to the same run-time
library that VS2008 does, it shouldn't matter what compiler is used to
create the binary.

You'd have to rebuild them all from source.  I don't know that it's
impossible, but I'll bet it would be a challenge.
