	* sem_disp.adb (Check_Controlling_Type): Handle properly the
	case of an incomplete type whose full view is tagged, when a
	primitive operation of the type is declared between the two views.

	* adaint.c (__gnat_locate_exec_on_path): If the PATH environment
	variable is not set, do not return NULL, because we can still find
	the executable if it includes a directory name.

	* sem_elab.adb (Elab_Warning): Under dynamic elaboration, when
	elaboration warnings are enabled, emit proper warning header
	when triggered by an access attribute.

	* exp_ch11.adb: If CodePeer_Mode is true, generate simplified
	SCIL for exception declarations.
	* exp_ch11.adb (Expand_N_Exception_Declaration) If CodePeer_Mode
	is True, initialize the Full_Name component of the exception
	record to null instead of to the result of an unchecked
	conversion.

	* exp_unst.adb (Note_Uplevel_Ref) : Handle properly a reference
	that denotes a function returning a constrained array, that has
	been rewritten as a procedure.
	* makeutl.ads: Minor edit.
