Not sure if the flag is safe but I don't think portage will pick up on |
24 |
changes to CFLAGS. You will have to do a emerge -e for all the packages |
25 |
to be compiled with the new setting. |

You could also just change it and let the packages update over time as |
28 |
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 |
32 |
page somewhere that gives the best CFLAGs but I can't find it. Still |
33 |
looking tho. |
