	* exp_ch9.adb (Build_Lock_Free_Unprotected_Subprogram_Body): Also
	initialize Block_Decls variable.
	(Expand_Entry_Barrier): Add pragma Warnings on Func_Body variable.
	(Build_Dispatching_Requeue): Add pragma Warnings on Op variable.
	* exp_disp.adb (Expand_Interface_Actuals): Initialize
	Formal_DDT and Actual_DDT variables.
	(Expand_Interface_Thunk): Initialize Iface_Formal.
	(Make_DT): Initialize Size_Comp.
	(Make_Select_Specific_Data_Table): Initialize Decls.
	* exp_dist.adb (Add_RACW_Primitive_Declarations_And_Bodies):
	Also initialize more RPC_Receiver_* variables.

	* sem_ch6.adb (Freeze_Type_Refs): For an interface conversion
	node between access types, freeze the designated type as well,
	so that dispatch table pointers are created in the proper scope,
	and not in the constructed body of the expression function.

	* alloc.ads (Nodes_Initial): Go back to previous value. The large
	value makes large compilations faster, but small compilations slower.

	* sem_util.adb: minor typos in Is_Child_Or_Sibling.

	* erroutc.adb (Compilation_Errors): Do not consider info messages
	as suitable warnings when warnings must be treated as errors.
	* sem_ch7.adb (Analyze_Package_Specification): Do not consider
	internally-generated packages when outputting completion
	information.
	* errout.adb (Output_Messages): Do not consider info messages as
	suitable warnings when warnings must be treated as errors.
	* errutil.adb (Finalize): Do not consider info messages as
	suitable warnings when warnings must be treated as errors.

	* warnsw.ads: Minor fix for incorrect wording in comment.

2017-04-28  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (In_Instance_Code): New predicate in
	Valid_Conversion, to determine whether a type conversion appears
	as (or within) an actual for a formal object.  Type conversions
	in instances are not rechecked in Valid_Conversion because
	visibility changes between generic location andi instance may
	lead to spurious errors, but conversions within an actual must be
	fully checked, and they are not fully resolved when pre-analyzing
	the actuals.
