-Os gave a 50% slowdown. The difference between macro/local
function/function in base class was then minor (the function in base
class was slightly *quicker* than the others, but I didn't pay attention
to system load or do many tests).

BTW, this is on a 2.8Ghz Celeron. Things might be different on CPUs with
more cache, etc.
