*Sigh*. I am so tired of this completely wrong information showing up here. |

1. It does not matter what -OX flag gcc is compiled with. It has |
| 8 |
absolutely *zero* effect on the code that gcc *generates*. |

2. There is also absolutely no reason to build gcc twice. There is no |
| 11 |
such thing as a gcc that was built with the "system compiler", because |
| 12 |
gcc uses itself to build itself. It is called a 3-stage bootstrap, |
| 13 |
and I suggest you read the gcc documentation first if you want to |
| 14 |
debate this point. |
