2017-12-05  Bob Duff  <duff@adacore.com>

	* exp_ch6.adb (Build_In_Place_Formal): Search for the formal by suffix
	instead of the full name.
	* sem_ch6.adb (Create_Extra_Formals): Make sure there are extra formals
	in the case of an instance of a generic.

2017-12-05  Arnaud Charlet  <charlet@adacore.com>

	(Adjust_Global_Switches): Create an alias GNAT_Annotate to map to
	pragma Annotate.
