I've just installed gcc 2.95 (19990714 prerelease) and couldn't help
notice the decrease in compile speed. A rather large library used to
take 8 min with gcc 2.8.1. It now takes just over 11 minutes. An
increase of 37% !
 
Here's the gcc-flags if that would matter:
 
  CFLAGS = -c -O2 -g -I../inc -Wall -m486 -malign-loops=2 \
           -malign-jumps=2 -malign-functions=2 -fno-strength-reduce
 
I'm quite sure the 2 builts where run under equal conditions;
disk-cache was flushed and no LAN was attached.
