/* This one is a tough one. Technically, this should return a struct, that's
   using however the older gcc ABI. There's no way to reproduce the ABI
   with modern gcc as far as I know, but it's also likely the rest of
   the returned struct isn't actually used, so we might be lucky here
   in terms of API. As far as ABI is concerned however, inlined assembly
   code will solve the issue. */
