I'm probably missing something here, but is there any reason
you cannot add this code to Py_InitModule4 instead:

   PyObject *m, *d, *v;
   PyMethodDef *ml;
+ if (!Py_IsInitialized())
+    Py_FatalError("Bad Python version"); /* Never returns */
   if (module_api_version !=3D PYTHON_API_VERSION)
    fprintf(stderr, api_version_warning,
