That looks like a start. Also,

py_days_of_month = (uint32_t)object->days_of_month > LONG_MAX ?  PyLong_FromUnsignedLong((uint32_t)object->days_of_month) : PyInt_FromLong((uint32_t)object->days_of_month);

this pattern can easily be put into a helper function. In
addition to having just one coverity warning (or none if we
properly #ifdef this) we get less cluttered code to look at.
