That explains it. It's too bad that there isn't a GCC for > Windows (out of alpha at least) that supports Core 2 optimizations. :-( As far as I've experienced, there is zero measurable benefit from -march higher than pentium2 (except for SSE float math maybe), and GCC's autovectorization is patently worthless.
