 Message        <Context> using array syntax to declare a parameter
                that is a pointer to an incomplete array type may not
                be portable.

 Description    Although this array parameter declaration conforms to
                the C standard (since it is equivalent to a pointer
                to the inner array), other C compilers may not accept
                it.

 User Action    Be aware of this difference if you plan to port this
                source to another compiler.
