	comments.

	* s-os_lib.ads, s-os_lib.adb, prj-err.adb, makeutl.adb: Minor
	reformatting.

2009-10-27  Ed Schonberg  <schonberg@adacore.com>

	* sem.util.ads, sem_util.adb (Denotes_Same_Object,
	Denotes_Same_Prefix): New functions to detect overlap between actuals
	that are not by-copy in a call, when one of them is in-out.
	* sem_warn.ads, sem_warn.adb (Warn_On_Overlapping_Actuals): New
	procedure,  called on a subprogram call to warn when an in-out actual
	that is not by-copy overlaps with another actual, thus leadind to
	potentially dangerous aliasing in the body of the called subprogram.
	Currently the warning is under control of the -gnatX switch.
	* sem_res.adb (resolve_call): call Warn_On_Overlapping_Actuals.

	* makeutl.adb (Check_Source_Info_In_ALI): Do not recompile if a subunit
	from the runtime is found, except if gnatmake switch -a is used and this
	subunit cannot be found.

2009-10-27  Ed Schonberg  <schonberg@adacore.com>

	* gnatbind.adb (gnatbind): When the -R option is selected, list subunits
	as well, for tools that need the complete closure of the main program.

	* prj-tree.adb (Free): Fix memory leak.

2009-10-27  Vasiliy Fofanov  <fofanov@adacore.com>

	* adaint.c, s-os_lib.adb (__gnat_create_output_file_new): New function
	that ensures the file that is created is new. Use this function to make
	sure there is no race condition if several processes are creating temp
	files concurrently.

	* exp_ch4.ads (Integer_Promotion_Possible): New subprogram.
	* exp_ch4.adb (Integer_Promotion_Possible): New subprogram.
	(Expand_N_Type_Conversion): Replace code that checks if the integer
	promotion of the operands is possible by a call to the new function
	Integer_Promotion_Possible. Minor reformating because an enclosing
	block is now not needed.
	* checks.adb (Apply_Arithmetic_Overflow_Check): Add missing check to
	see if the integer promotion is possible; in such case the runtime
	checks are not generated.
