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).

10 them in a timely fashion (reported by Denis Bilenko). 34 them in a timely fashion (reported by Denis Bilenko).

14 syserr, loop acquire/release, periodic reschedule cbs). 38 syserr, loop acquire/release, periodic reschedule cbs).
15 - fix event_base_loop return code, add event_get_callback, event_base_new, 39 - fix event_base_loop return code, add event_get_callback, event_base_new,
16 event_base_get_method calls to improve libevent 1.x emulation and add 40 event_base_get_method calls to improve libevent 1.x emulation and add
17 some libevent 2.x funcitonality (based on a patch by Jeff Davey). 41 some libevent 2.x functionality (based on a patch by Jeff Davey).

28 the kqueue descriptor in the child. 52 the kqueue descriptor in the child.
53 - work around linux inotify not reporting IN_ATTRIB changes for directories
54 in many cases.
29 - include sys/syscall.h instead of plain syscall.h. 55 - include sys/syscall.h instead of plain syscall.h.

31 common reported usage bug in ev_io_start. 57 common reported usage bug in ev_io_start.
32 - chose socket vs. WSASocket at compiletime using EV_USE_WSASOCKET. 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).
