[Bug c/19390] New: Accepts invalid code (well I don't know if it is invalid or not but I think it should be)

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I don't see why we just reject the following code:
extern short int aa[][];

In Comeau's compiler, in both C89 and C99 mode, they reject it.

Though we have to be care full not to reject:
 union incomplete (*foo)[4];
which is only undefined in C89 but it is invalid in C99
