	* libgnat/a-cbdlli.adb, libgnat/a-cbhama.adb,
	libgnat/a-cbmutr.adb, libgnat/a-cborma.adb: Rename New_Item to
	be Default_Initialized_Item, and apply pragma Unmodified to it,
	to suppress the warning.

2017-09-12  Eric Botcazou  <ebotcazou@adacore.com>

	* exp_aggr.adb (Aggr_Assignment_OK_For_Backend): Add early return
	for access types.

2017-09-12  Yannick Moy  <moy@adacore.com>

	* gnat1drv.adb (Adjust_Global_Switches): Consider Refined_Global
	together with Global when ignoring one in CodePeer mode.

2017-09-12  Javier Miranda  <miranda@adacore.com>

	* sem_ch3.adb (Analyze_Declarations): In nested
	package declarations that have a private part enable missing check
	of the RM rule 13.1.1(11/3): usage names in aspect definitions are
	resolved at the end of the immediately enclosing declaration list.
