Hello,
Current CFLAGS="-O2 -march=i686 -pipe"
I want to add "-fomit-frame-pointer" to my
CFLAGS on an existing system that has been running
for months.
Is this safe or do I have to rebuild everything with
somelike "emerge -e" ?
Should it be avoided completely?

Not sure if the flag is safe but I don't think portage will pick up on
changes to CFLAGS. You will have to do a emerge -e for all the packages
to be compiled with the new setting.
You could also just change it and let the packages update over time as
they get upgraded. I don't think that will cause any problems.
You can also look here:
http://www.gentoo.org/doc/en/gcc-optimization.xml Also note, there is a
page somewhere that gives the best CFLAGs but I can't find it. Still
looking tho.
