Daniel noticed that, per to the resolution of DR195, we shouldn't warn
in c++11 mode, not even with -pedantic, for this kind of

sure if we want to do something slightly different for C++98, or
something more.

I think we should apply DR195 to C++98, too. We might add the warningto a new -Wconditionally-supported flag that could later warn aboutother conditionally-supported constructs as well.
