SubjectRe: GCC speed (was [PATCH] Isapnp warning)
If you think 3.[23] are slow, go back and compile with 2.7.2 - it's much 
faster than the later versions. I used to yank newer versions of gcc
off systems and put 2.7.2 on, I think it was close to 2x faster at
compilation and made no difference on BK performance.
