Log message:
	Fix for EINTR returns from Win9X socket operations:
	
	In summary, if a software writer implements timer events or other events
	which generate a signal with a timing fast enough to occur while libpq
	is inside connect(), then connect returns -EINTR.  The code following
	the connect call does not handle this and generates an error message.
	The sum result is that the pg_connect() fails.  If the timer or other
	event is right on the window of the connect() completion time, the
	pg_connect() may appear to work sporadically.  If the event is too slow,
	pg_connect() will appear to always work and if the event is too fast,
	pg_connect() will always fail.
