Modified files:
	cygwin         : ChangeLog exceptions.cc miscfuncs.cc 

Log message:
	* exceptions.cc (CALL_HANDLER_RETRY_INNER): Rename to reflect different
	functionality.
	(CALL_HANDLER_RETRY_OUTER): New define.
	(setup_handler): Add outer loop to signal handler to try harder to deliver the
	signal.
	* miscfuncs.cc (yield): Drop priority and use SleepEx() to force thread
	rescheduling rather than relying on SwitchToThread().
