You don't need to downgrade. You can just emerge it alongside 4.5.3 and
switch to it with "gcc-config". You can switch back and forth at will,
meaning that you can build specific packages with 4.4.5 and keep the
rest of the packages on 4.5.3.
Or if you really want everything built with 4.4.5, you can switch to it
with "gcc-config" and then "emerge -e world".
