My guess is that they won't because it would dramatically decrease the subset of code that is both valid C and valid C++ in many environments. As you are no doubt aware, most C -- not all, and not with perfectly preserved semantics -- is valid C++ in practice. I think the C committee would have to do something first. But I'm only an outside observer.
