It looks like this is a Python 2.3 error. In Python 2.4, the
PyLong_AsUnsignedLong was changed to accept Python integers as well as
The problem with fixing it is I'm not sure where PyLong_AsUnsignedLong
is being called. I can't find that call in the current source code.
It's possible that Pyrex changed and this function is no longer being
used in mtrand.c
