This is in a Semantics section of the standard, not Constraints, so no
diagnostic is required, but as a quality-of-implementation matter we should
diagnose it.

Addition to "Notes" above.

3. C11, 5.1.1.3 Diagnostics, 1:
> A conforming implementation shall produce at least one diagnostic message 
> (identified in an implementation-defined manner) if a preprocessing 
> translation unit or translation unit contains a violation of any syntax rule 
> or constraint, even if the behavior is also explicitly specified as undefined 
> or implementation-defined.
