I am not sure about your compiler, but if I remember the standard correctly, the following code shouldn't complain:

PyObjectCallFunction((PyObject*) (void *) &PyRangeType, "lll", start, start+len*step, step)

You remember the standard incorrectly. Python's usage of casts has undefined behaviour, and adding casts only makes the warning go away, but does not make the problem go away.
