What is wrong with a new libstdc++? It is supposed to be thread-safe.
There are quite a few C++ packages which need a thread-safe libstdc++.
I was even asked to make a patch for egcs 1.0.3 to generate the
thread-safe libstdc++. I told them to wait for egcs 1.1. Making
libstdc++ in egcs 1.1 on RedHat thread-unsafe and not compatible with
other Linux configurations is a very big mistake. I hope RedHat won't
do that.
