Attached is the patch for the the mathmodule.c file of Python 2.6a3 
containing the C version of the msum() function from Marks's msum4.py 
Python implementation.

Please review the C code, in particular the setting of _do_sum_pow_2 for 
FLT_RADIX not equal to 2.

The results of the C and Python versions match (on 32-bit MacOS X 
Intel), using the test_math_sum4.py script.  That includes all the tests 
from msum4.py and from Raymond's recipe.

More testing and the cmath version are still to be done.
