deps/libev/Changes

 Revision history for libev, a high-performance and full-featured event loop.
 
-TODO: ev_loop_wakeup
-TODO: EV_STANDALONE == NO_HASSEL (do not use clock_gettime in ev_standalone)
-TODO: faq, process a thing in each iteration
-TODO: dbeugging tips, ev_verify, ev_init twice
-TODO: ev_break for immediate exit (EVBREAK_NOW?)
-TODO: ev_feed_child_event
-TODO: document the special problem of signals around fork.
-TODO: store pid for each signal
-TODO: document file descriptor usage per loop
-TODO: store loop pid_t and compare isndie signal handler,store 1 for same, 2 for differign pid, clean up in loop_fork
-TODO: embed watchers need updating when fd changes
-TODO: document portability requirements for atomic pointer access
-TODO: document requirements for function pointers and calling conventions.
+4.23 Wed Nov 16 18:23:41 CET 2016
+	- move some declarations at the beginning to help certain retarded
+          microsoft compilers, even though their documentation claims
+          otherwise (reported by Ruslan Osmanov).
 
 4.22 Sun Dec 20 22:11:50 CET 2015
 	- when epoll detects unremovable fds in the fd set, rebuild
