In principle, users can install libgcc* wherever they like.  I think
the install path for shared libraries is hardcoded in executables (otool -L).
There's also DYLD_LIBRARY_PATH and DYLD_FALLBACK_LIBRARY_PATH.  As
far as I know, the libgcc libraries shipped with 4.3 and in 4.4 are
backwards compatible with earlier versions.

My impression is that this issue is not confined to libgcc.  The same
problem is present for all the libraries provided by gcc.  Any added
features are going to make the new version incompatible with the system
version, irrespective of ABI changes.
