make.conf

Here is my new make.conf.I use Kde and Fluxbox (split and toolbar in USE).
You alse have to install ccache and my processor is Intel(R) Core(TM)2 Quad  CPU   Q9550  @ 2.83GHz.That's why I put march=native?

# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /usr/share/portage/config/make.conf.example for a more
# detailed example.
CFLAGS="-O2 -march=native -pipe"
CXXFLAGS="${CFLAGS}"
# WARNING: Changing your CHOST is not something that should be done lightly.
# Please consult http://www.gentoo.org/doc/en/change-chost.xml before changing.
