	* sinfo.ads, sinfo.adb: New semantic attribute Premature_Use,
	present in incomplete type declarations to refine the error
	message the full declaration is in the same unit.
	* sem_ch4.adb (Analyze_Selected_Component): If the prefix is of
	an incomplete type, set the Premature_Use for additional message.
	* sem_ch3.adb (Find_Type_Name): If partial view is incomplete
	and Premature_Use is set, place additional information at the
	point of premature use.
