 Message        <Context> a storage class without a declarator is
                meaningless.

 Description    This message is generated when the compiler
                encounters certain declarations that contain a
                storage class but no declarator.  For example:
                extern struct S { int a;};

 User Action    Either remove the storage class or add a declarator
                to the declaration.
