 Message        <Context> the bitfield type is not an integral type.

 Description    A bitfield has been declared with a non-integral
                type.  Standard C requires that all bitfields be
                declared with either int, unsigned int, or signed int
                type.

 User Action    Change the type of the bitfield.
