> What do Linux distros do w.r.t. multiple compiler versions?

In debian, everything goes in /usr and subdirectories get split as necessary.

In /usr/bin: gcc-3.3, gcc-4.1, gcc-4.3 and a symlink gcc

In /usr/lib (or /lib): the latest of each version of a runtime library, so for instance libstdc++.so.5 from gcc-3.3 and libstdc++.so.6 from gcc-4.3 but no version from gcc-4.1 which uses the compatible one from gcc-4.3

/usr/include/c++ and /usr/lib/gcc/$ARCH contain subdirectories with names 3.3, 4.1, 4.3 (and symlinks 4.1.2, 4.3.1)
