requires that errno ever get set, and it looks like glibc is already playing that game. New rules: + Never use HUGE_VAL. Use the new Py_HUGE_VAL instead. + Never believe errno. If overflow is the only thing you're interested in, use the new Py_OVERFLOWED(x) macro. If you're interested in any libm errors, use the new Py_SET_ERANGE_IF_OVERFLOW(x) macro, which attempts to set errno the way C89 said it worked. Unfortunately, none of these are reliable, but they work on Windows and I *expect* under glibc too.

Rework the way we try to check for libm overflow, given that C99 no longer
