	* exp_ch4.adb, exp_ch6.adb, prj-nmsc.adb: Minor reformatting.

2011-09-02  Hristian Kirtchev  <kirtchev@adacore.com>

	* exp_util.adb (Extract_Renamed_Object): Renamed to
	Find_Renamed_Object. This routine has been reimplemented and now uses
	tree traversal to locate a renamed object.
	(Is_Aliased): Replace call to Extract_Renamed_Object with
	Find_Renamed_Object.

2011-09-02  Tristan Gingold  <gingold@adacore.com>

	* init.c: (__gnat_is_vms_v7): New function.

2011-09-02  Olivier Hainque  <hainque@adacore.com>

	* tracebak.c (STOP_FRAME, ppc elf/vxworks case): Stop on frames
	that have a misaligned backchain, necessarily bogus.
