/* 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. */
