Possible but relatively small. It will probably have a new libstdc++
ABI as development continues, but allow interlibrary calling without
recompilation otherwise.
The difference here is that GCC 3.0 had a rewritten ABI, which had
never before been implemented in any compiler (but is planned to be
implemented in others, e.g. Intel's, I believe. Maybe it has now.).
GCC 3.1 is merely fixing bugs in that implementation, which
unfortunately broke compatibility. For instance, there was a change in
which temporary objects were destroyed by callee where they used to be
destroyed by caller (or the other way round. I don't remember.).
