Yes. I got a test case failing when I upgraded my machine from linux-ppc
(32) to linux-amd64 because the expected answer to fac(13) was
6227020800L and linux 64bits gives 6227020800 (no "L") instead. I
changed the test to
as fac(20) is still a "regular" int (2432902008176640000) in 64 bits, so
I'm safe for a few years, and I hope the int/long unification in py3k
will free me of this problem.
