	* sem_attr.adb (Analyze_Attribute): Check dimension for attribute
	Old before it gets expanded.
	* sem_dim.adb (Analyze_Dimension_Has_Etype): Correctly propagate
	dimensions for identifier.

2012-10-02  Ed Schonberg  <schonberg@adacore.com>

	* exp_ch5.adb (Expand_Iterator_Loop): Handle properly the case
	where the iterator type is derived locally from an instantiation
	of Ada.Iterators_Interface.
	* exp_ch7.adb (Establish_Transient_Scope): Do not create a
	transient scope if within the expansion of an iterator loop,
	because a transient block already exists.

2012-10-02  Vincent Celier  <celier@adacore.com>

	* gnatcmd.adb: Use absolute path for configuration pragmas files
	* make.adb (Configuration_Pragmas_Switch.Absolute_Path): Moved
	to Makeutl.
	* makeutl.ads, makeutl.adb (Absolute_Path): New function, moved from
	make.adb.

2012-10-02  Vincent Celier  <celier@adacore.com>

	* prj-part.adb (Post_Parse_Context_Clause): Resurrect Boolean
	parameter In_Limited.  Check for circularity also if In_Limited
	is True.
	(Parse_Single_Project): Call Post_Parse_Context_Clause with
	In_Limited parameter.
