Here is the updated patch for type module based on Zachary's comment.

However, I can not convert this method.

{"__subclasshook__", object_subclasshook, METH_CLASS | METH_VARARGS,
     object_subclasshook_doc},

static PyObject *
object_subclasshook(PyObject *cls, PyObject *args)
{
    Py_RETURN_NOTIMPLEMENTED;
}

>>> type.__subclasshook__()
NotImplemented
>>> type.__subclasshook__('cutecat')
NotImplemented
>>> type.__subclasshook__('cutecat', 1, [])
NotImplemented
