Message        <Context> the element type of an array type is
                incomplete.

 Description    The element type of an array type is incomplete at
                the point in the program where the array is declared.
                While HP C will allow this if the element type is
                completed later, other compilers might require the
                type to be complete at this point in the program.

 User Action    Either complete the type before the array
                declaration, or be aware of this if you wish to port
                the program.
