[issue4575] Py_IS_INFINITY defect causes test_cmath failure on x86

Fixed (I hope!) in the trunk in r69459.  I'll wait for buildbot results 
(just in case) and then merge to 2.6, 3.1 and 3.0.

The same test_cmath failure can also be seen on OS X 10.5.6/Intel when 
compiling with -fmpmath=387.  Annoyingly, the fix above doesn't work here:  
it seems that the OS X isinf is buggy.  It doesn't seem worth working 
around this bug though, since there's little sane reason to be compiling 
with -fmpmath=387 in the first place, so it's unlikely that any regular 
Python users will encounter this problem.

----------
resolution:  -> fixed
versions:  -Python 2.7
