I can't really consider a 166MHz/64MB machine slow and small
(looking at my firewall appliance at 66MHz/32MB and dealing with
embedded systems with 8MB of RAM - granted then never compile anymore).
Getting old? Yes.  "slow" not for my def of "slow".

Try building on a 32MB sparc 1 or 2 or a 486/50.

-pipe is good if you have RAM to spare.  Perhaps it could be added
if there's a way to programatically check RAM size for > 128MB.
