p.s.: Current version of GCC is 4.0.1. I hope MinGW can use newest version of GCC and Code::Blocks can use newest version of MinGW.IIRC, the fact that GCC went to version 4 is not because it's a big improvement over previous versions (yet), but because of major internal changes in the way it works, that should lead to improved optimization opportunities and cleaner internals.
