New submission from Jean Brouwers <MrJean1 at Gmail.com>:
The attached patch bltmodule2.c.diff is a different implementation of
the fast summation code for your consideration.
It uses three separate sums to add ints, floats and other objects. All
ints are accumulated into a C long, reset even after overflow. All
floats are added into a C double without mixing ints. Other objects are
handled as before.
This version has been tested with Python 2.5.2 as well and passed the
existing regressions.
