yup - its just plain 32 bit mode (don't I feel like a dinosaur now?).
Well, what you *should* feel is the pain that you don't get *another* 20
% performance increase when running your laptop in 64 bit mode (I've
been using laptops like that - under Debian - since mid-2005).
64 bits gives you more integer and floating point registers, SSE
instructions by default (you didn't enable them on your compilation),
hence vectorization (at -O3), etc.
Cheers :-)
