Which is an obvious thinko in this last step, because make check was run
with the same g++ as libstdc++.so.5.0.0.
I've rerun the tests after swapping back gcc directories, ie.
3.2 libstdc++ source + built with g++ 3.3 + make check run against it with g++ 3.2
3.3 libstdc++ source + built with g++ 3.2 + make check run against it with g++ 3.3
but the results were the same, ie. 25 XPASSes, 1 FAIL.
