2017-04-25  Ed Schonberg  <schonberg@adacore.com>

	* sem_ch4.adb (Analyze_Selected_Component): Refine analysis
	of prefix whose type is a current instance of a synchronized
	type. If the prefix is an object this is an external call (or
	requeue) that can only access public operations of the object. The
	previous predicate was too restrictive, and did not allow public
	protected operations, only task entries.
