Update of /cvsroot/python/python/dist/src/Objects
In directory usw-pr-cvs1:/tmp/cvs-serv23901/python/Objects
Modified Files:
	floatobject.c 
Log Message:
float_divmod(): the code wasn't sick enough to stop the MS optimizer
from optimizing away mod's sign adjustment when mod == 0; so it got
the intended result only in the debug build.
