ARRNOTLVALUE

Message        <Context> accepting a non-lvalue array in a subscript
               operator is an extension to the C89 standard.

Description    The C89 standard states that one of the operands to
               the subscript operator must be a pointer.  However,
               the array used in this operator could not be
               converted to a pointer because it is not an lvalue.
               Therefore this code does not conform to the C89
               standard and may not be accepted by other compilers.
               Note that the C99 standard allows this because all
               arrays are converted to pointers, not just lvalue
               arrays.

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