The manual says:

-- Replacement: long get_run_time (void)
Returns the time used so far, in microseconds. If possible, this
is the time used by this process, else it is the elapsed time
since the process started.

Without looking at the code, I would guess it's just a wrapper for getrusage
and it uses something like gettimeofday for elapsed time when it can't find
it. I think if user time isn't available it's best just to make
-enable-timings fail, so I'll use Eli's suggestion.
