-- fix compiler warning about return "from incompatible pointer type" when
returning Python exceptions. EXPP_ReturnPyObjError() always returns a
NULL because Python expects error conditions to return a NULL pointer
instead of an object. Since the pointer is cast to a PyObject *, it's
ugly to use for propagating the errors back in this case, so this fix just
uses PyErr_SetString() to set the error and return NULL (see the body
of EXPP_ReturnPyObjError() ).
