Its the same with FreeBSD users. We knew it was rfc1035.c a while back. :)
(I think there is a disucssion about it on squid-dev somewhere..)

Define "files that break". Under what OS? With what versions of what
compiler?

What does -O2 buy us speed-wise that -O doesn't? I dont think the
resultant binary size matters much (compared to how much RAM
squid needs to run.. :)

Personally, I think -O is enough right now, but I'd like to let
people experiment by modifying the optimisation level without needing
to tweak configure.
