	* exp_attr.adb (Expand_N_Attribute_Reference, case 'Access and
	Unchecked_Access): If the context is an interface type, and the prefix
	is of the corresponding class-wide type, do not insert a conversion
	because the pointer displacement has already taken place, and we must
	retain the class-wide type in a dispatching context.

	* prj-nmsc.adb, prj-env.adb (Override_Kind): Unset the unit field of
	the previous source file.
	(Create_Mapping): Iterate on sources rather than on units.
