2017-09-07  Arnaud Charlet  <charlet@adacore.com>

	* sem_util.adb (Check_Part_Of_Reference): rename Conc_Typ to Conc_Obj
	(because it refers to the anonymous concurrent object, not its type);
	fix condition for emitting error message about task/protected type,

2017-09-07  Bob Duff  <duff@adacore.com>

	* binde.adb (Debug_Flag_Old): If both -do and -dp
	are specified, behave as if just -do was specified, rather than
	using a mixture.

2017-09-07  Nicolas Roche  <roche@adacore.com>

	* system-vxworks-sparcv9.ads, s-vxwork-m68k.ads, s-vxwork-mips.ads,
	system-vxworks-m68k.ads, system-vxworks-mips.ads: Removed.
