261Very rarely, people want to tweak EV even more, e.g. to exclude
262or include certain watcher types or backends. This can be done by adding
263extra -D options here, or via the EV_EXTRA_DEFS environment variable.
264
265For example, if you run into compile problems because of missing memory
266fences (or you just want extra performance), you can tell EV to not support
267smp and threads via -DEV_NO_THREADS.
