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.
