 Message        <Context> the array bound "<expression>" is not a
                positive integer.

 Description    The compiler has encountered an array-bounds
                specifier that is either zero or negative.
                Array-bounds specifiers must be positive integer
                constants.

 User Action    Correct the array-bounds specifier
