Experimental CFLAGS. To quote the gcc documentation: |

|

The following options control optimizations that may improve |
| 9 |
performance, but are not enabled by any `-O' options. This section |
| 10 |
includes experimental options that may produce broken code. |

-ftracer |

-fprefetch-loop-arrays |

At a minimum, take these out and "emerge -Dev system". I would also |
| 19 |
take out all of the mmx and sse flags, and let those be enabled by USE |
| 20 |
flags for those packages where it is known to be safe to do so. |

Finally, please turn off HTML email. |
