187On GNU/Linux systems, EV uses the LSB 3.1 __register_atfork function
188to avoid the dependency on libpthread, and directly uses the clock_gettime
189syscall to avoid a dependency on librt.

248EOF 253Very rarely, people want to tweak EV even more, e.g. to exclude
254or include certain watcher types or backends. This can be done by adding
255extra -D options here, or via the EV_EXTRA_DEFS environment variable.
249 256
257For example, if you run into compile problems because of missing memory
258fences (or you just want extra performance), you can tell EV to not support
259smp and threads via -DEV_NO_THREADS.
