One of the reasons I've gone to all the trouble of upgrading my three bots
is that I have a self-hosting bot that already tests clang. If I moved them
to clang, we'd probably regress when compiling with GCC. It's rare, but can

Another issue is the libstdc++ that Chandler is also moving forward because
of many bugs in C++11 and C++03 libraries.

In the end, if we need to upgrade the libraries, why not upgrade the whole
distribution? It's a lot easier, too. ;)
