2014-01-24  Pascal Obry  <obry@adacore.com>

	* prj-attr.adb, projects.texi, snames.ads-tmpl: Add Excluded_Patterns
	attribute definition.

2014-01-24  Vincent Celier  <celier@adacore.com>

	* makeutl.adb (Queue.Insert_No_Roots): In gprbuild, do not put
	in the Queue the same source (same path, same multi-source index)
	from the same project file, to avoid compiling several times
	the same source.

2014-01-24  Eric Botcazou  <ebotcazou@adacore.com>

	* einfo.ads (First_Rep_Item): Remove obsolete stuff.
	(Has_Gigi_Rep_Item): Likewise.
	* sem_prag.adb (Analyze_Pragma) <Pragma_Linker_Section>: Do not set
	Has_Gigi_Rep_Item for objects.
	* gcc-interface/decl.c (prepend_one_attribute_to): Rename into...
	(prepend_one_attribute): ...this.
	(prepend_one_attribute_pragma): New function extracted from...
	(prepend_attributes): ...here.  Swap the parameters for consistency.
	(gnat_to_gnu_entity): Adjust calls to prepend_one_attribute_to and to
	prepend_attributes.
	<object>: Deal with a pragma Linker_Section on a constant
	or variable.  <E_Function>: Deal with a pragma Linker_Section
	on a subprogram.
	(get_minimal_subprog_decl): Adjust calls to prepend_one_attribute_to.
