The only real need to re-emerge packages is if the new gcc version updates |
| 18 |
your version of libstdc++, because that lib is supplied by each new version |
| 19 |
of the gcc package: |
| 20 |
|
| 21 |
$ls -l /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++* |
| 22 |
-rw-r--r-- 1 root root 2237388 2010-06-06 13:16 /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++.a |
| 23 |
lrwxrwxrwx 1 root root 19 2010-06-06 13:17 /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++.so -> libstdc++.so.6.0.13* |
| 24 |
lrwxrwxrwx 1 root root 19 2010-06-06 13:17 /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++.so.6 -> libstdc++.so.6.0.13* |
| 25 |
-rwxr-xr-x 1 root root 954472 2010-06-06 13:16 /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++.so.6.0.13* |
| 26 |
-rw-r--r-- 1 root root 2384572 2010-06-06 13:16 /usr/lib/gcc/i686-pc-linux-gnu/4.4.3/libstdc++_pic.a |

The only packages on your machine that would be affected by the gcc update are those |
| 29 |
packages that are linked against the OLD version of libstdc++.so. Running revdep-rebuild |
| 30 |
should rebuild/reinstall all of those packages. Theoretically speaking, of course :) |
