 Sorry for my ignorance, what is syntactically wrong with that?

It is semantically incorrect and not syntactically incorrect.  Basically
-fsyntax-only includes most of the semantics analysis, why not this one too.

I should note that the diagnostic is produced in varasm.c while it really
should be produced in the front-end.
