	* gcc-interface/Make-lang.in (ADA_TOOLS_FLAGS_TO_PASS, native): use
	$(CXX) instead of ../../xg++ to feed CXX.
	(CXX_LFLAGS): Remove. Now unused as the proper flags
	are expected to be included in the CXX variable.

2014-08-01  Pierre-Marie Derodat  <derodat@adacore.com>

	* gcc-interface/decl.c (elaborate_expression_1): Return the new
	variable when debug info is needed and the expression is not
	constant.  Tag as external only new variables that are global.
	(gnat_to_gnu_entity): Call it after the GNU declaration is saved.
	* gcc-interface/trans.c (Attribute_to_gnu): Do not cache
	attributes for IN array parameters when their actual subtype
	needs debug info.
	(Compilation_Unit_to_gnu): Call it to process all remaining nodes.
	* gcc-interface/gigi.h (process_deferred_decl_context): New.
	* gcc-interface/utils.c (gnat_write_global_declarations): Do not
	emit debug info for ignored global declarations.
	(struct deferred_decl_context_node,
	add_deferred_decl_context, add_deferred_type_context,
	compute_deferred_decl_context, defer_or_set_type_context,
	deferred_decl_context_queue, get_debug_scope,
	get_global_context, process_deferred_decl_context): New.
	(gnat_pushdecl): Re-implement the DECL_CONTEXT and TYPE_CONTEXT
	computation machinery to rely on the GNAT Scope attribute.
