You need a small fixup to support python-2.4. For instance, the deprecation
warning is implemented as:

#if PY_VERSION_HEX >= 0x02050000
#define DEPRECATE(msg) PyErr_WarnEx(PyExc_DeprecationWarning,msg,1)
#else
#define DEPRECATE(msg) PyErr_Warn(PyExc_DeprecationWarning,msg)
#endif

Thanks for settling this discussion ;)
