+- The documentation for the tp_compare slot is updated to require that
+ the return value must be -1, 0, 1; an arbitrary number <0 or >0 is
+ not correct. This is not yet enforced but will be enforced in
+ Python 2.3; even later, we may use -2 to indicate errors and +2 for
+ "NotImplemented". Right now, -1 should be used for an error return.

- PyLong_AsLongLong() now accepts int (as well as long) arguments.
Consequently, PyArg_ParseTuple's 'L' code also accepts int (as well
as long) arguments.
