If a diagnostic is a non-fatal warning, then you say that the compiler
doesn't consider it an error. I disagree; as has been said many times,
a non-fatal warning is a valid diagnostic for an error.
So 3 out of 6 correctly diagnosed the error, 2 fatally and 1
non-fatally.
The other three compilers are non-conforming *in the mode in which you
invoked them*. Can you make them conforming with appropriate options?

If you invoke a compiler *in conforming mode*, you can't get away with
writting "any old rubbish".
