The old GCC version does not get removed. This is a good thing just in |
| 21 |
case the new one doesn't work for some reason. |

If it works OK, you can manually unmerge the old version: |
| 24 |
|
| 25 |
emerge -aC gcc:4.4 |
| 26 |
|
| 27 |
Before doing that, however, make sure the new one has been activated |
| 28 |
with gcc-config and verify that it works by building some random package. |
