Revision history for libev, a high-performance and full-featured event loop.
- backport inotify code to C89.
- implement EV_WIN32_HANDLE_TO_FD and EV_WIN32_CLOSE_FD configuration
symbols to make ti easier for apps to do their own fd management.

- incompatible change: do not necessarily reset signal handler

=item EV_FD_TO_WIN32_HANDLE(fd)
If C<EV_SELECT_IS_WINSOCKET> is enabled, then libev needs a way to map
file descriptors to socket handles. When not defining this symbol (the
@ -3673,6 +3673,20 @@ default), then libev will call C<_get_osfhandle>, which is usually
correct. In some cases, programs use their own file descriptor management,
in which case they can provide this function to map fds to socket handles.
=item EV_WIN32_HANDLE_TO_FD(handle)
If C<EV_SELECT_IS_WINSOCKET> then libev maps handles to file descriptors
using the standard C<_open_osfhandle> function. For programs implementing
their own fd to handle mapping, overwriting this function makes it easier
to do so. This can be done by defining this macro to an appropriate value.
=item EV_WIN32_CLOSE_FD(fd)
If programs implement their own fd to handle mapping on win32, then this
macro can be used to override the C<close> function, useful to unregister
file descriptors again. Note that the replacement function has to close
the underlying OS handle.
If defined to be C<1>, libev will compile in support for the C<poll>(2)
