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

If it works OK, you can manually unmerge the old version:

   emerge -aC gcc:4.4

Before doing that, however, make sure the new one has been activated 
with gcc-config and verify that it works by building some random package.
