	* einfo.ads, einfo.adb (Is_Underlying_Record_View): New subprogram
	(Set_Is_Underlying_Record_View): New subprogram

	* sem_aggr.adb (Discr_Present, Resolve_Record_Aggregate): In case of
	private types with unknown discriminants use the underlying record view
	if available.

	* sem_ch3.adb (Build_Derived_Private_Type): Enable construction of the
	underlying record view in the full view of private types whose parent
	has unknown discriminants.
	(Build_Derived_Record_Type): Avoid generating the class-wide entity
	associated with an underlying record view.
	(Derived_Type_Declaration): Avoid deriving parent primitives in
	underlying record views.

	* sem_ch6.adb (Check_Return_Subtype_Indication): Add support for
	records with unknown discriminants.

	* sem_type.adb (Covers): Handle underlying record views.
	(Is_Ancestor): Add support for underlying record views.

	* exp_attr.adb (Expand_Attribute): Expand attribute 'size into a
	dispatching call if the type of the target object is tagged and has
	unknown discriminants.

	* exp_aggr.adb (Resolve_Record_Aggregate): Add support for records with
	unknown discriminants.

	* exp_disp.adb (Build_Dispatch_Tables): Avoid generating dispatch
	tables for internally built underlying record views.

	* sprint.adb (sprint_node_actual): Improve output of aggregates with an
	empty list of component associations.

	* sem_ch10.adb: Minor reformatting

	* socket.c, g-socthi-vms.adb, g-socthi-vms.ads, g-socthi-vxworks.ads,
	g-socthi-mingw.ads, g-socthi.ads, g-socket.adb
	(GNAT.Sockets.Inet_Addr): Do not use non-portable inet_aton, instead use
	standard inet_pton API (and emulate it on platforms that do not
	support it).
	(GNAT.Sockets.Thin.Inet_Pton, VMS case): Implement in terms of
	DECC$INET_ADDR, imported in Ada.
	(GNAT.Sockets.Thin.Inet_Pton, VxWorks and Windows cases): Use C
	implementation provided by GNAT runtime.
	(__gnat_inet_pton): C implementation of inet_pton(3) for VxWorks and
	Windows.
