	* sem_attr.adb (Analyze_Attribute, case 'Access): If the prefix

	* sem_res.adb (Resolve_Explicit_Dereference): Do not add an access
	check if the type of the prefix is known to exclude null.
	* a-coinve.adb (Get_Element_Access): The function returns an
	access type that excludes null, so add an explicit check for
	a null element pointer, which is created when Insert_Spaces is
	called on an indefinite vector container.
