Our build system (for Haiku) disables some optimizations when not used with GCC 2. This was needed as the GCC 3 we had did not work correctly. I doubt GCC 4 will still have the same limitations, though. In any case, one should just enable the optimizations again and see if everything is still working right :-) Bye, Axel.
