--- Comment #7 from Ian Lance Taylor <ian at airs dot com> --- I'm a little worried because I'm not 100% confident that clock_gettime is available in the standard library on all systems. I don't want to break GCC 5 is that is the case. Admittedly I haven't seen any bug reports on mainline yet, but it's only been a few days.
