I seem to remember some comment in this group that tokenising accounts
for a big chunk of a compiler's runtime (50% or something).

While it is true that doing a full compile will take longer than just
raw tokenising, should that factor be of the order of 1000 times longer,
or three magnitudes?

I was investigating whether a reasonable working compiler could be
developed working at between 1 and 2 magnitudes slow-down from the raw
tokenising speed.

Probably one magnitude is a little optimistic, for C source anyway (with
preprocessing and stuff also needed), but two magnitudes is easily on
the cards. I think Tiny C is within that range.
