Problem with python inside C?

So im trying to implement python, and when i do Py_initialize(), I crash. what the fuck is that? I have an error inside codeblocks about the :

/usr/include/python2.7/pyconfig.h|1161|warning: "_POSIX_C_SOURCE" redefined [enabled by default]|

/usr/include/features.h|215|note: this is the location of the previous definition|

doesnt make sense. halp?

Shalom! xD
