12 - add throw() to all libev functions that cannot throw exceptions, for
13 further code size decrease when compiling for C++.
14 - add throw () to callbacks that must not throw exceptions (allocator,
15 syserr, loop acquire/release, periodic reschedule cbs).
16 - fix event_base_loop return code, add event_get_callback, event_base_new,
17 event_base_get_method calls to improve libevent 1.x emulation and add
18 some libevent 2.x funcitonality (based on a patch by Jeff Davey).
19 - add more memory fences to fix a bug reported by Jeff Davey. Better
20 be overfenced than underprotected.
21 - ev_run now returns a boolean status (true meaning watchers are
22 still active).
23 - ev_once: undef EV_ERROR in ev_kqueue.c, to avoid clashing with
24 libev's EV_ERROR (reported by 191919).
25 - (ecb) add memory fence support for xlC (Darin McBride).
26 - (ecb) add memory fence support for gcc-mips (Anton Kirilov).
27 - (ecb) add memory fence support for gcc-alpha (Christian Weisgerber).
28 - work around some kernels losing file descriptors by leaking
29 the kqueue descriptor in the child.
30 - include sys/syscall.h instead of plain syscall.h.

33 - INCOMPATIBLE CHANGE: ev_timer_again now clears the pending status, as
34 was documented already, but not implemented in the repeating case.
35 - new compiletime symbols: EV_NO_SMP and EV_NO_THREADS.
