I think Jack is confused regarding --enable-libstdcxx-timer.  From emailing me,
he seems to be under the impression that '--enable-libstdcxx-timer' is
equivalent to '--enable-libstdcxx-timer=no' ... if that is the case, then
something is certainly wrong since --enable-libstdcxx-timer should be
equivalent to '--enable-libstdcxx-timer=yes' ...

As for darwin ... we have sched_yield and nanosleep.  We don't have
clock_gettime.

Why are you testing for posix timer support in your checks for sched_yield and
nanosleep?
