	* makeutl.adb: Minor reformatting.

2011-08-03  Vincent Celier  <celier@adacore.com>

	* fname-uf.adb
	(Get_File_Name) If the file cannot be found when there are no config
	pragmas file and May_Fail is True, return No_File instead of the file
	name, to be consistent.

2011-08-03  Pascal Obry  <obry@adacore.com>

	* adaint.c (__gnat_is_executable_file_attr): Avoid access
	to null pointer.

2011-08-03  Javier Miranda  <miranda@adacore.com>

	* sem_ch13.adb
	(Same_Representation): In VM targets the representation of arrays with
	aliased components differs from arrays with non-aliased components.
