	* sem_ch12.adb (Analyze_Package_Instantiation,
	Analyze_Subprogram_Instantiation): Turn off style checking while
	analyzing an instance. Whatever style checks that apply to the generic
	unit should apply, so it makes no sense to apply them in an instance.
	This was causing trouble when compiling an instance of a runtime
	unit that violates the -gnatyO switch.
	* stylesw.adb (Set_Style_Check_Options): "when 'O' =>" was missing from
	one of the two case statements, causing spurious errors.

	* uname.adb: Minor reformatting.
	* gnatcmd.adb: Minor reformatting.
	* exp_attr.adb: Minor reformatting.
