libtool is only part of the problem. Assume you have an application
built with gcc4, which uses a shared library built with gcc3. As a
result you get an application linked to two different versions of
libgcc. I don't know if this is supposed to work, but I wouldn't trust
such a binary. I think in the situation you described, switching
completely and exclusively over to the newest compiler is the only
option, which may result in rebuilding lots of packages.
