Richard Smith 5407d4f9be DR330: when determining whether a cast casts away constness, consider ...

qualifiers from all levels matching a multidimensional array.

For example, this allows casting from
  pointer to       array of            array of   const volatile int
to
  pointer to const pointer to volatile pointer to                int
because the multidimensional array part of the source type corresponds
to a part of the destination type that contains both 'const' and
'volatile'.
