In addition to -Os, -O will accept any non-negative integer as an argument. |

Currently, anything above 3 does nothing extra. From what I understand, |
| 8 |
there have been undocumented levels up to 6, but they have always been |
| 9 |
considered unstable (which is why they never appeared in documentation). |

The quickest way to recognize a Gentoo ricer is someone that |
| 12 |
has -O4, -O6, -O99 or something else equally stupid in their CFLAGS. -O3 |
| 13 |
is defensible, as it is at least *supposed to be* stable; anything higher |
| 14 |
is just stupid. |
