This is since Python header file is in debug mode and you link with the
regular library.

Just do:
    #undef _DEBUG /* Link with python24.lib and not python24_d.lib */
    #include <Python.h>

and you'll be fine.

IMO python should try and link with python24.lib when compiling in debug
mode since we want to debug our program and not Python.
