2010-06-14  Vincent Celier  <celier@adacore.com>

	* prj-nmsc.adb (Add_Sources): Always set the object file and the
	switches file names, as the configuration of the language may change
	in an extending project.
	(Process_Naming_Scheme): For sources of projects that are extended, set
	the configuration of the language from the highest extending project
	where the language is declared.

	* sem_res.adb (Resolve_Call): For infinite recursion check, test
	whether the called subprogram is inherited from a containing subprogram.
	(Same_Or_Aliased_Subprograms): New function
