[issue2819] Full precision summation

[Jean Brouwers]

Jean Brouwers <MrJean1 at Gmail.com> added the comment:

Here is another patch for the mathmodule.c and cmathmodule.c files updated 
with the suggested and other modifications.  Note, if FLT_RADIX is not 2, 
the sum functions still exist but will raise a NotImplementedError.

An update of the test script is also attached.  The tests all pass on the 
same 4 Python 2.6a3 builds mentioned before.
