Summary: Py_OVERFLOWED should be isinf() on openbsd

Initial Comment:
test_long and test_complex both fail on OpenBSD/x86.

The problem is essentially that:



>>> shuge = '12345' * 120 

>>> float(int(shuge))

Inf



while on everything else, this raises an OverflowError.



Making the #ifdef in Include/pyport.h that sets

Py_OVERFLOWED to isinf() also do the same for OpenBSD

fixes this. I'm proposing to fix this for 2.3.2,

because then we're passing all tests on openbsd (minus

the wackiness from the HP testdrive boxes).



Tim, is there any reason to not add an autoconf test

for the presence of isinf(), and always use it for

Py_OVERFLOWED if it's present? Using it on this Redhat

9 system doesn't seem to break anything (well, the test

suite passes).



Obviously not going to make the latter change for

2.3.2, but is it appropriate for the trunk?
