the app would ignore foo by itself and usually people are working on |
| 6 |
having their tailored x86 code in shape for amd64 (using some tricks as |

usual...) |

I feel afraid since we are spending lot of time assuming our users don't |
| 10 |
have a clue about what they bought or that they cannot document |
| 11 |
themselves as they should for picking the right cpu/tune for the CFLAGS... |

Diego's proposal could be nice for remove some options and prevent the |
| 14 |
burden of keeping a long list of useflag due the Intel vs Amd war on the |
| 15 |
extensions, sadly I think was pointed that isn't a complete solution and |
| 16 |
many would be unhappy about it. |

Having a USE_EXPAND for the cpu feats could a little improvement if we |
| 18 |
expect sse99 or 5dnowultra appear within the year since we could stuff |
| 19 |
all this cruft in a single place and have a separate use.desc for them. |
