Standard CFLAGS

[nukes]

Is there a way to set GCC and G++ to use a set of CFLAGS by default without having to put them in every time I do a ./configure The sort of thing I want is:
CFLAGS="-mcpu=athlon-xp -O3 -pipe"
Any way to do this? Do I have to set up an alias or something or can I just edit something in /etc / rebuild autoconf/gcc or something?

Just put something like

export CFLAGS="-mcpu=athlon-xp -O3 -pipe"
export CXXFLAGS="$CFLAGS"

in your ~/.bashrc

I would use -Os and -march though

You use Gentoo right? You just add these to /etc/env.d/00basic and run env-update

Yeah, thanks. I was just wondering if there was a way to do it for all the stuff I compile outside portage. Thanks.
