This is the patch I talked about in #1334662.  I think
it fixes int() returning zero for non-zero literals
under some bases.

I *love* this web interface...  Here you have the patch.

This is a little modification to ``test_builtin.py`` to
check for the bug.  It would be nice for someone to run it
under a 64-bit platform!
