could someone check this? I'm pretty sure that (on pentiums!),
4 byte alignment is worse than either zero or 16 byte alignment,
and there is no point in wasting space when zero alignment is at
least equally well.

I never saw benchmark data (except mine) that said 4 byte is better then
zero byte alignment (and intel itself recommends 0 on pentiums).
