 32   These were mostly implemented in GCC around GCC-4.8; older versions
 33   have no, or only partial support.  To provide a level of backwards
 34   compatibility we try to work out what the definitions should be, given
 35   the older pre-defines that GCC did produce.  This isn't complete, but
