It shouldn't be. Clang 3.4 is C++11-feature-complete.
I was thinking of Clang 3.1 or thereabouts and it shouldn't be rejected
either. Think of XCode 5.0 that some people might be still using.

I already gave you a list. It might not be complete, but I think it is.
More importantly, if you had used the list, it would catch issues that aren't
being caught right now with the incomplete version-based check.

It shouldn't be. We've never had that. Adding that thing to an LTS release
before we know how things work...
