* c-common.h (objc_build_method_signature): Update prototype.

	* stub-objc.c (objc_build_method_signature): Update the stub
	implementation to accept and ignore additional parameter.
	* c-parser.c (c_parser_objc_method_decl): Reorgnize to pass
	the value of ellipsis to objc_build_method_signature instead
	of setting TREE_OVERFLOW on the parms TREE_LIST node.

	* objc-act.h (METHOD_ADD_ARGS_ELLIPSIS_P): New macro for accessing
	this field of an objc method decl.
	* objc-act.c (build_method_decl): Take an additional "ellipsis"
	argument, and set METHOD_ADD_ARGS_ELLIPSIS_P as appropriate.
	(objc_build_method_signature): Accept additional "ellipsis"
	argument and pass it to build_method_decl.
	(get_arg_type_list, start_method_def, gen_method_decl): Use
	the new METHOD_ADD_ARGS_ELLIPSIS_P instead of examining the
	TREE_OVERFLOW field of a TREE_LIST node.
