249Very rarely, people want to tweak EV even more, e.g. to exclude
250or include certain watcher types or backends. This can be done by adding
251extra -D options here, or via the EV_EXTRA_DEFS environment variable.
252
253For example, if you run into compile problems because of missing memory
254fences (or you just want extra performance), you can tell EV to not support
255smp and threads via -DEV_NO_THREADS.
