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