The GCC 2.95 Caveats page (<http://egcs.cygnus.com/gcc-2.95/caveats.html>)
says

Is there a more detailed description of what the known
incompatibilities are, and/or what C++ features might
trigger them, and/or whether there is a subset of C++ that
one might reasonably expect to work compatibly, say from
egcs 1.1 to gcc 2.95?
And is there anything describing likely C++ ABI changes in
near-future releases (2.9x for x > 5; and/or 3.0)?
Thanks,
