These were mostly implemented in GCC around GCC-4.8; older versions

have no, or only partial support. To provide a level of backwards

compatibility we try to work out what the definitions should be, given

the older pre-defines that GCC did produce. This isn't complete, but

it should be enough for use by routines that depend on this header. */
