A case has turned up of early-stage-1 failures where folks have installed
the new 3.1 gcc but still have the leftover 2.95 libstdc++.so and get
failures due to missing _cxx_abi_v0 type symbols. This is a temporary
bootstrap problem that affects systems that were built with half of the
compiler only. I specifically tested on a pre-gcc-3.1 system and survived.
People who built world in betweed /usr/bin/c++ going live and this commit
are affected.
Possible solution: Something evil like this:

This would be temporary and would go away in a week or two.
Or, tell the handful of early 3.1 adopters on -current:
cd /usr/src/gnu/lib
make obj
make includes
cd libstdc++
make depend && make && make install
cd ../libsupc++
make depend && make && make install
I'll test this out a bit more and see if the bandaid works.
Cheers,
-Peter
