/* 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. */
