Why? I don't agree that it needs to be the global useflags, but I don't |
| 4 |
consider it illegal either. |

It's defined by toolchain.eclass and toolchain-binutils.eclass, and |
| 7 |
deliberately in a very careful manner, such that USE=-multislot and |
| 8 |
USE=multislot do NOT conflict. There are no other uses in the tree. |

For binutils, it simply enables slotting entirely. |
| 11 |
For gcc, it moves the slot down from the major version to the minor version. |
| 12 |
|
| 13 |
In both cases, which one gets called is controlled by the relevant *-config |
| 14 |
utility. It's pretty handy when you are trying to figure out a gcc or binutils |
| 15 |
bug in the minor versions. |
