Summary: structmember T_LONG won't accept a python long

Initial Comment:
An attribute defined as T_LONG throws a vague error
when set to a python long, even when the value is 
within the range of a LONG.

TypeError: bad argument type for built-in operation

The DEVMODE object from pywintypes has attributes defined 
as T_LONG via the structmember API.

>>> import pywintypes
>>> dm=pywintypes.DEVMODEType()
>>> dm.Position_x=3
>>> dm.Position_x
3
>>> dm.Position_x=long(3)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
TypeError: bad argument type for built-in operation
>>>

Here's the relevant code from structmember.c
that throws the error:
	case T_LONG:
		if (!PyInt_Check(v)) {
			PyErr_BadArgument();
			return -1;
		}
		*(long*)addr = PyInt_AsLong(v);
		break;

Can you provide example code that demonstrates what you mean?
