You mean when support for it is not detected?

Since EV_USE_CLOCK_SYSCALL defaults to off on solaris, EV_USE_REALTIME is
defined to be 1. This in line with documentation for EV_STANDALONE,
EV_USE_REALTIME and EV_USE_CLOCK_SYSCALL, so it seems it is intended.

EV_STANDALONE also isn't documented to somehow minimise os usage,
and clock_gettime is rather important for timekeeping purposes, so
should be provided if possible.

EV_STANDALONE is documented to not rely on autoconfig, but instead on a
manually provided configuration. It seems to me that if you want to avoid
using realtime calls you can just define EV_USE_REALTIME to 0 in your
custom config.

If this somehow doesn't work for you, then I'd be interested to hear why.
