The May draft (no, my copy *still* hasn't come, dammit, but I've borrowed
a friend's because time is running out) has the grammar set up in such a
way that at least one storage class specifier ("extern" etc.), type
specifier ("int" etc.), or type qualifier ("const" etc.) must appear.
Some compilers may well accept a more general syntax for the sake of
backwards compatibility.
