Here's a patch that fixes the problems with math.sum on x86 machines that 
aren't using SSE2.

On these machines, the patched version of math.sum does almost the entire 
calculation using long doubles instead of doubles.  Then in the final 
summation, the top long double is split into a double and a residue long 
double.
