Did anyone actually test this patch? :)

I admit I did not build it on Windows specifically because I assumed
that was done as part of the development and review. And the changes
to pg_event.c can never have built, since the file does not include
the required header.

I have reverted that part of the patch for now, hopefully that'll
unbreak the buildfarm.

For the time being at least I left the other changes to DEFAULT_EVENT_SOURCE in.
