The default is set to 2.95.x (at least on i386 archs). So calling gcc or
g++ will give you the 2.95.x version (this is what gcc is symlinked to,
which you can verify by doing "ls -la $(which gcc)" ). This is done
because not everything yet supports version 3.0. If you want gcc 3.0 you
need to invoke it explicitly by gcc-3.0 or g++-3.0 .
For more, see the README.Debian.gz in usr/share/doc/gcc-3.0 .
