/* On PowerPC, in versions of GCC up to at least 4.7.2, a type cast -- which is
   a IEEE 754-2008 general-computational convertFormat operation (IEEE
   754-2008, 5.4.2) -- does not turn a sNaN into a qNaN (whilst raising an
   INVALID exception), which is contrary to IEEE 754-2008 5.1 and 7.2.  This
   renders certain tests infeasible in this scenario.
