No, that's a very bad idea. It should not be necessary to rebuild the
whole system with the new compiler, but you should at least follow the
revdep-rebuild path of upgrading the compiler.
http://www.gentoo.org/doc/en/gcc-upgrading.xml#upgrade-3.3-to-3.4
The problem is the libstdc++ library. If you don't at least do the
revdep-rebuild, you could end up with some things that are linked
against both libstdc++.so.6 and libstdc++.so.5, and they will crash
miserably.
