Update of /cvsroot/python/python/dist/src/Objects
In directory usw-pr-cvs1:/tmp/cvs-serv21887/python/Objects
Modified Files:
floatobject.c
Log Message:
float_abs() again: Guido pointed out that this could screw up in the
presence of NaNs. So pass the issue on to the platform libm fabs();
after all, fabs() is a std C function because you can't implement it
correctly in portable C89.
