	(Xref_Entry): redefine information needed in cross-references for ALFA.
	Push ALFA treatments in separated local package.
	(Enclosing_Subpragram_Or_Package): treat specially subprogram
	identifiers. Return entity of package body instead of spec. Return
	Empty for a scope with no location.
	(Generate_Reference): adapt to new components for ALFA information.
	Remove the need for D references on definitions.
	(Is_Local_Reference): moved to ALFA local package
	(Output_References): extract subfunction as Extract_Source_Name
	(Output_Local_References): remove procedure, replaced by filtering of
	cross-references in package ALFA and printing in Put_ALFA.
	(Write_Entity_Name): remove procedure
	* lib.adb, lib.ads (Extract_Source_Name): extract here function to
	print exact name of entity as it appears in source file
	(Unit_Ref_Table): make type public for use in Lib.Xref.ALFA
	* put_alfa.adb, put_alfa.ads: New files.
	* xref_lib.adb (Search_Xref): protect read of cross-references against

2011-08-03  Jose Ruiz  <ruiz@adacore.com>

	* s-inmaop-vxworks.adb (Setup_Interrupt_Mask): Do nothing instead of
	raising an exception.

2011-08-03  Ed Schonberg  <schonberg@adacore.com>

	* sem_res.adb (Set_String_Literal_Subtype): if index type is an integer
	type, always use 1 as the lower bound or string, even if lower bound of
	context is not static, to handle properly null strings in a non-static
	context.

2011-08-03  Bob Duff  <duff@adacore.com>

	* sem_prag.adb (Resolve_Aggregate): An array aggregate with 'others' is
	always legal on the right-hand side of an assignment statement; there
	is always an applicable index constraint in this case. Therefore, the
	check for Pkind = N_Assignment_Statement is now unconditional -- it
	doesn't depend on whether Is_Constrained (Typ).
