	reference objects are reclaimed on each iteration of the loop.
	* sem_ch5.adb (Analyze_Loop_Statement): Mark the generated block
	tasked with the handling of container iterators as requiring

	* exp_ch3.adb (Expand_N_Object_Declaration): When a class-wide
	object is declared, it is rewritten as a renaming of an dynamic
	expression that wraps the initial value.  The renaming declaration
	is first given an internal name, to prevent collisions with the
	entity already declared, and then the name is modified to reflect
	the original one. the modification of the name must preserve
	the source location of the original, to prevent spurious errors
	when compiling with style checks if the declaration involves
	more than one entity.
