Whoops! I didn't carefully read the examples, supposing that they were
all of the kind expressing reordering of the type-specifier and
storage-class. This last example has more than one storage class and
more than one type-specifier, so is illegal.

As an aside, catching this kind of error in the grammar can really
make the grammar *huge*. This is why one does it outside the grammar.
