If you ran the same source compiled as C and as C++, the results should have been pretty much the same. There are some semantic differences, but you won't find them by summing large arrays. Apparently GNU's C++ front end isn't as good as its C front end. -- Michael hennebry@xxxxxxxxxxxxxxxxxxxxx "Pessimist: The glass is half empty. Optimist: The glass is half full.
