Correct: we don't expose the Standard Library's ABI in our ABI, so any 
breakages they have wouldn't affect us.

We do depend on the C++ support ABI (libsupc++, which in most distros not 
shipping libc++ is supplied as part of libstdc++). That library hasn't broken 
compatibility, so it should be no problem.
