 Message        <Context> the referenced type of the pointer value
                "<expression>" is __unaligned, but the referenced
                type of the target of this assignment is not.

 Description    In an assignment of two pointer types, the type
                pointed to by the destination operand must have all
                the type qualifiers of the type pointed to by the
                source operand.  In this case, the type pointed to by
                the source has the __unaligned type qualifier, but
                the type pointed to by the destination does not.

 User Action    Correct the assignment to use compatible types.  This
                can be done by inserting a cast operand.
