	cygwin         : ChangeLog fhandler.cc syscalls.cc 

Log message:
	* fhandler.cc (fhandler_base::close): Move setting isclosed() from here to
	closed().
	(fhandler_base_overlapped::close): Correct comment.
	(fhandler_base_overlapped::destroy_overlapped): Signal overlapped event before
	closing it to potentially wake up a waiting thread.
	(fhandler_base_overlapped::wait_overlapped): Expand setting of err when closed
	to encompass non-signal event.  Test for a cancel event before making
	nonblocking decisions.
	* syscalls.cc (close): Set closed flag here so that any concurrently executing
	functions will be notified ASAP.
