 If defined to be C<1>, libev will try to detect the availability of the
-real-time clock option at compile time (and assume its availability at
-runtime if successful). Otherwise no use of the real-time clock option will
-be attempted. This effectively replaces C<gettimeofday> by C<clock_get
-(CLOCK_REALTIME, ...)> and will not normally affect correctness. See the
-note about libraries in the description of C<EV_USE_MONOTONIC>, though.
