- update for EV 3.0 API changes.

2.8  Sun Nov 25 15:06:03 CET 2007
- waitpid can validly return 0. accept this fact of life
  instead of reporting it to any watchers.

2.7  Fri Nov 23 11:41:14 CET 2007
- force use of AnyEvent::Impl::Perl in testsuite, there is
  too much breakage outside AnyEvent.
- deliver signals synchronously in AnyEvent::Impl::Perl
  or any other event loop that relies on AnyEvents child
  watcher emulation. *Could* help with hanging testsuite
  (except when Event or EV are installed).

- fix bug in testsuite.
- move EV adaptor modules to AnyEvent.

2.55 Tue Nov  6 17:41:32 CET 2007
- add EV to the list of supported event models.
- do not auto-reset pid watchers, pass pid and status to them.
- allow a pid of zero to watch for all children in child watchers.

2.54 Wed Jul 18 17:36:23 CEST 2007
- work around a perl bug that results in
  BEGIN not safe after errors--compilation aborted without
  any discernible reason or error message by once
  again not use'ing strict.

2.53 Sun Jul  8 10:51:53 CEST 2007
- make Glib interface work again (spotted by elmex).
