I've /never/ done an emerge -e world after a glibc upgrade, nor do I |
| 11 |
believe it's needed. After a major gcc upgrade, it may or may not be |
| 12 |
needed, but it's a good idea in any case, since you should get better |
| 13 |
optimizations out of it. (Major in this case is either 3.x to 4.x, major |
| 14 |
version, or 4.1 to 4.2, minor version. It shouldn't be needed for micro |
| 15 |
version, 4.1.1 to 4.1.2 say.) |

Note that C++ is more sensitive than C, in terms of program language, |
| 18 |
since C++ has a library, libstdc++, that's part of the gcc package, and is |
| 19 |
actively changing with new gcc versions. C programs are much less |
| 20 |
sensitive and often still work where C++ programs stop. |
