"-ftree-parallelize-loops" and automataic parallelization for makepkg
I have a computer with a Core2 Duo. Would it be recommended to set -ftree-parallelize-loops=2 flag in makepkg.conf? Is there a better way to activate automatic parallelization in GCC (I use 4.4).
Thank you!

Well, if you want to, then that seems fine.
If you are recompiling official packages, realise that the time you spend recompiling stuff will not be gained back by faster execution speeds.

I tried -ftree-parallelize-loops=4 with my quad-core back when I was using Funtoo. Quite a few things did break. As long as you're okay with dealing with breakage and rebuilding those packages with that CFLAG filtered out, go right ahead and try (let us know your experience, too).
