   double types, include math.h so it can choose what is the appropriate
   nextafterl function to use.

   If we didn't use -fno-builtin for this test, the PowerPC compiler would have
   changed the names of the built-in functions that use long double.  The
   nextafter-1.c function runs with this mapping.

   Since this test uses -fno-builtin, include math.h, so that math.h can make
   the appropriate choice to use.  */
