If you use gcc-2.95 then this doesn't break anything. With gcc-3.x
however, glibc and X break with -fomit-frame-pointer. These are the two
major packages which need to be built without this flag. About others, I
don't know as I haven't come across any yet. In fact, I've used my regular
flags (-march=athlon-tbird -mmnx -m3dnow -O3 -pipe -fomit-frame-pointer)
on qt also (by editing the correspoding qmake.conf) with gcc-3.1 and there
are no problems.
