No - the only requirement is that a diagnostic be produced. A fully
conforming implementation of C is allowed to accept such code and then
generate an executable; if you choose to execute the executable, the
behavior is undefined.
The only construct for which rejection is mandatory is a #error
directive that survives conditional compilation. Note that a #error
directive that contains or is a syntax error or a constraint violation
would invalidate that requirement, allowing the program to be accepted.
