// Rather ugly but at least it suppresses compiler errors...
// Unfortunately, this of course *does* have an severe impact on
// dependant libraries, actually this is chrono only! Here it will
// not be possible to correctly use user and system times! But
// as vxWorks is lacking the ability to calculate user and system
// process times there seems to be no other possible solution.
