I agree with Richard's response to the other other parts of your mail, but I'd also add that -O2 may not be the best setting for your system. -Os applies some of the optimisations of -O3 but also optimises for size. It is often the best setting for systems with slow memory and disk I/O, i.e. laptops. -- Neil Bothwick A bug in the hand is better than one as yet undetected.
