257Very rarely, people want to tweak EV even more, e.g. to exclude
258or include certain watcher types or backends. This can be done by adding
259extra -D options here, or via the EV_EXTRA_DEFS environment variable.
260
261For example, if you run into compile problems because of missing memory
262fences (or you just want extra performance), you can tell EV to not support
263smp and threads via -DEV_NO_THREADS.
