emerge -e world if cflags got changed |

emerge --newuse world if useflags got changed. |

But there is no reason to recompile the whole system because of some changed |
| 10 |
cflags. After some updates everything got recompiled anyway ;) |

no, after a normal -uD world you don't have to do anything. Maybe |
| 16 |
revdep-rebuild if something does not work anymore. But nothing else is |
| 17 |
needed. |

After a gcc-update.. well, it depends. |
| 20 |
|
| 21 |
from gcc 3.4.x to 3.4.x+1 nothing needs to recompile. Everything is fine. |
| 22 |
from gcc 3.x to 4.x emerge -e system, emerge -e world is more or less a must. |

Please read the gcc-upgrade guide on the gentoo homepage. |
