2012-07-30  Hristian Kirtchev  <kirtchev@adacore.com>

	* sem_ch12.adb (Earlier): Add local variables T1 and T2. Minor code
	refactoring.

2012-07-30  Thomas Quinot  <quinot@adacore.com>

	* gnatcmd.adb, make.adb, makeutl.adb, makeutl.ads
	(Test_If_Relative_Path): Rename to Ensure_Absolute_Path to better
	reflect what this subprogram does. Rename argument Including_L_Switch
	to For_Gnatbind, and also exempt -A from rewriting.
	* bindusg.adb: Document optional =file argument to gnatbind -A.

2012-07-30  Ed Schonberg  <schonberg@adacore.com>

	* freeze.adb (Freeze_Entity): Do no apply restriction check on
	storage pools to access to subprogram types.
