The Py_InitModule4_64 hack prevents that:

Include/modsupport.h:94:

#if SIZEOF_SIZE_T != SIZEOF_INT
/* On a 64-bit system, rename the Py_InitModule4 so that 2.4
   modules cannot get loaded into a 2.5 interpreter */
#define Py_InitModule4 Py_InitModule4_64
#endif

And that, too (if you mean 'on 64-bit platforms'; if you don't, I don't know
why we should try and prevent that.)
