You don't need to downgrade. You can just emerge it alongside 4.5.3 and |
| 15 |
switch to it with "gcc-config". You can switch back and forth at will, |
| 16 |
meaning that you can build specific packages with 4.4.5 and keep the |
| 17 |
rest of the packages on 4.5.3. |
| 18 |
|

Or if you really want everything built with 4.4.5, you can switch to it |
| 20 |
with "gcc-config" and then "emerge -e world". |
