Thanks all for torturing your boxes with fmod()! Would still like to hear
about Platforms from Mars (Macs <wink>, Tru64, HP-UX), but it got a clean
bill of health on all these:

dying with OverflowError in math.fmod(). Looks like a *badly* buggy fmod()
to me!
If we had tried this a decade ago, *most* platforms would have gotten a
wrong answer on almost every try. Assuming we don't get a failure report on
Mac, the major platforms do this correctly now, so we can save Python from
growing another few hundred lines of excruciating workaround code:
