* c-decl.c: Fix typos in several comments. Remove all

	#if 0 blocks; reindent as needed.  Remove unused argument
	to declare_parm_level; all callers changed.
	* c-parse.in: Update calls to declare_parm_level.  Avoid
	issuing a double warning in some circumstances.
	* c-typeck.c: Update calls to declare_parm_level.
	* c-tree.h: Update prototype of declare_parm_level.

	* c-pragma.c (apply_pragma_weak): Don't complain about a
	redundant #pragma weak.

	* objc/objc-act.c (forward_declare_categories,
	build_selector_reference_decl, build_class_reference_decl,
	build_objc_string_decl, synth_forward_declarations,
	build_protocol_reference): Set TREE_PUBLIC on synthetic
	forward decl to 0, consistent with eventual definition.
	Correct comments to match.

cp:
	* pt.c (get_bindings): Make definition consistent with
	forward declaration.
