Does that matter?  I checked the patch in on the Python trunk, and
that's 2.5 to me ;-)  The change was in:

static void
CField_repr(CFieldObject *self)

and:

typedef struct {
	PyObject_HEAD
	Py_ssize_t offset;
	Py_ssize_t size;
	Py_ssize_t index;		/* Index into CDataObject's
					   object array */
	PyObject *proto;		/* a type or NULL */
	GETFUNC getfunc;		/* getter function if proto is NULL */
	SETFUNC setfunc;		/* setter function if proto is NULL */
} CFieldObject;

has Py_ssize_t all over the place, and that's unique to 2.5 (so far) too, right?
