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'.
