	* sinfo.ads: Minor reformatting.
	* sem_aux.ads: Clarify use of First_Discriminant.
	* sem_ch4.adb (Analyze_Explicit_Dereference): The use of a limited
	view is replaced with the non-limited view in an instance body,
	where the enclosing unit must have a regular with_clause on the
	relevant unit.
	* sem_ch12.adb (Install_Body): Freeze instantation after its
	body. Remove useless freeze nodes for incomplete actuals to
	prevent multiple generation of internal operations.
	(Instantiate_Package_Body): Set sloc of body appropriately when
	there are incomplete actuals and the instance body is placed in
	the body of the enclosing unit.
	* errout.ads: Consistent punctuation, better alignment and trivial
	typos in comments.
	* err_vars.ads: Fix typo.

	components of Volatile_Full_Access objects.

	* sem_ch6.adb (Is_Non_Overriding_Operation,
	Get_Generic_Parent_Type): Handle properly the case of a derived
	scalar type by using the first subtype rather than its generated
	anonymous base type.

	* einfo.adb (Write_Field17_Name): Move E_Incomplete_Subtype
	case to...
	(Write_Field19_Name): ...here.
