dynamic module does not define init function with python 2.2 only

Question

I have a problem with the dynamic error module does not define init function (initsomething). Everything is fine when I use python 2.7, the problem only occurs with compilation using python 2.2 The output format is .pyd. My code in c++

#ifndef PyMODINIT_FUNC
#define PyMODINIT_FUNC void
#endif

extern "C" PyMODINIT_FUNC initsomething(void)
{
    (void)Py_InitModule("something", methods);
}
