Hmm. I've considered it, but I don't know what the appropriate action is... I suspect that it should *not* be "CXX11Compat" because technically the change was a DR against C++11 — sadly this is about portability to "older" compilers, not portability to "lesser" C++ standards. Of course it can't be "CXX98Compat", for several reasons. :) I'm not sure of the purpose of the "CXX..CompatPedantic" groups. They are all identical to the "CXX..Compat" groups, except that CXX98CompatPedantic includes one extra warning about binding to lifetime-extended temporaries which don't have copy constructors.
