/* This used to inject fesetround () calls to control the rounding mode of the
   actual executed floating point operation.  It turned out that supporting
   conversions using fesetround calls won't work in gcc due to it not being
   able to restrict code motions across calls at the moment.  This
   functionality is therefore disabled for now until a better solution is
   found or if fesetround () is fixed in gcc.  */
