2009-07-22 Thomas Quinot <quinot@adacore.com>

	* sem_util.adb, sem_ch10.adb: Minor reformatting

	* g-socket.adb (Receive_Socket, recvfrom(2) variant): Apply required
	special handling for the case of no data received and Item'First =
	Stream_Element_Offset'First.
	(Last_Index): New subprogram factoring the above special handling
	over the various locations where it is required.

2009-07-22  Arnaud Charlet  <charlet@adacore.com>

	* gnat1drv.adb (Gnat1drv): Also disable division by zero and alignment
	checks in CodePeer_Mode.
	* gcc-interface/Make-lang.in: Update dependencies.

2009-07-22  Ed Schonberg  <schonberg@adacore.com>

	* sem_aggr.adb: Improve error message.

	* sem_ch13.adb: If Ignore_Rep_Clauses is enabled, do a minimal analysis
	of an address representation clause.
	* freeze.adb (Freeze_Static_Object): An local imported object is legal
	if it has an address clause.
