	* sem_ch4.adb (Diagnose_Call): Improve error message when a
	selected component has a prefix that might be interpreted
	as a parameterless function call, but none of the candidate
	interpretations is parameterless, and there is a hidden homonym
	of the prefix that is a package.
	* sem_ch8.adb (Find_Selected_Component): If the prefix might be
	interpreted as a parameterless function call and its analysis
	fails, do not call Analyze_Selected_Component.
