	* einfo.adb (Has_Protected): Test base type.
	* sem_ch4.adb (Analyze_Allocator): Reorganize code to make sure
	that we always properly check No_Protected_Type_Allocators.

2014-07-29  Ed Schonberg  <schonberg@adacore.com>

	* sem_util.ads, sem_util.adb (Defining_Entity):	Now applies to
	loop declarations as well.
	* exp_ch5.adb (Expand_Loop_Statement): Apply Qualify_Entity_Names
	to an iterator loop, because it may contain local renaming
	declarations that require debugging information.

2014-07-29  Robert Dewar  <dewar@adacore.com>

	* sem_util.ads, exp_util.adb, sem_attr.adb: Minor reformatting.
