18 - mark event pipe fd as cloexec after a fork (analyzed by Sami Farin).
19 - (ecb) support m68k, m88k and sh (patch by Miod Vallat).
20 - use a reasonable fallback for EV_NSIG instead of erroring out
21 when we can't detect the signal set size.
22 - in the absence of autoconf, do not use the clock syscall
23 on glibc >= 2.17 (avoids the syscall AND -lrt on systems
24 doing clock_gettime in userspace).
25 - ensure extern "C" function pointers are used for externally-visible
26 loop callbacks (not watcher callbacks yet).
27 - (ecb) work around memory barriers and volatile apparently both being
28 broken in visual studio 2008 and later (analysed and patch by Nicolas Noble).

31 - destroying a non-default loop would stop the global waitpid
32 watcher (Denis Bilenko).
33 - queueing pending watchers of higher priority from a watcher now invokes
34 them in a timely fashion (reported by Denis Bilenko).
35 - add throw() to all libev functions that cannot throw exceptions, for
36 further code size decrease when compiling for C++.
37 - add throw () to callbacks that must not throw exceptions (allocator,
38 syserr, loop acquire/release, periodic reschedule cbs).
39 - fix event_base_loop return code, add event_get_callback, event_base_new,
40 event_base_get_method calls to improve libevent 1.x emulation and add
41 some libevent 2.x functionality (based on a patch by Jeff Davey).
42 - add more memory fences to fix a bug reported by Jeff Davey. Better
43 be overfenced than underprotected.
44 - ev_run now returns a boolean status (true meaning watchers are
45 still active).
46 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
47 libev's EV_ERROR (reported by 191919).
48 - (ecb) add memory fence support for xlC (Darin McBride).
49 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
50 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
51 - work around some kernels losing file descriptors by leaking
52 the kqueue descriptor in the child.
53 - work around linux inotify not reporting IN_ATTRIB changes for directories
54 in many cases.
55 - include sys/syscall.h instead of plain syscall.h.
56 - check for io watcher loops in ev_verify, check for the most
57 common reported usage bug in ev_io_start.
58 - choose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET.
59 - always use WSASend/WSARecv directly on windows, hoping that this
60 works in all cases (unlike read/write/send/recv...).
61 - try to detect signals around a fork faster (test program by
62 Denis Bilenko).
63 - work around recent glibc versions that leak memory in realloc.
64 - rename ev::embed::set to ev::embed::set_embed to avoid clashing
65 the watcher base set (loop) method.
66 - rewrite the async/signal pipe logic to always keep a valid fd, which
67 simplifies (and hopefully correctifies :) the race checking
68 on fork, at the cost of one extra fd.
69 - add fat, msdos, jffs2, ramfs, ntfs and btrfs to the list of
70 inotify-supporting filesystems.
71 - move orig_CFLAGS assignment to after AC_INIT, as newer autoconf
72 versions ignore it before
73 (https://bugzilla.redhat.com/show_bug.cgi?id=908096).
74 - add some untested android support.
75 - enum expressions must be of type int (reported by Juan Pablo L).

78 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
79 was documented already, but not implemented in the repeating case.
