As the others have already said, gcc-config is the way to switch between
gcc versions. In theory, every time you switch between different gcc's
you *should* run 'fix_libtool_files.sh <old-gcc-version-number>' *and*
recompile every package that links to libstdc++ (because libstdc++ is
part of the gcc package and gcc-config switches versions of libstdc++).
I suspect most people don't actually do those things, however :)
Just keep it in mind if any c++ applications start acting weird.
