/* 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. <https://gcc.gnu.org/PR56828>. */
