43	*
44	* There are two sets of flags: the unix mode flags and the dos attributes.
45	*
46	* APIs returning mode flags will provide both sets.
47	*
48	* When specifying mode flags to any API at least one of them must be given. If
49	* one set is missing the API will synthesize it from the one given if it
50	* requires it.
51	*
52	* Both sets match their x86 ABIs, the DOS/NT one is simply shifted up 16 bits.
53	* The DOS/NT range is bits 16 to 31 inclusively. The Unix range is bits 0 to 15
54	* (inclusively).
55	*
56	* @remarks These constants have been comitted to a binary format and must not
57	* be changed in any incompatible ways.
