	* 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.

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

	* 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.

	* s-os_lib.ads: Update comment.

	* 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.
