	structures.

	if appropriate.  Relocate to remove need for forward declaration.
	(implicitly_declare): Adjust for new bindings structures.  Kludge
	around Objective-C not-really-builtin functions.
	(undeclared_variable): Improve diagnostics.  If current_function_decl
	is nonnull but current_function_scope is null, use current_scope.

	Warn about YYDEBUG not being defined only if -dy.  Remove no-longer-
	correct loop over multiple translation units; call fatal_error if

	IMA temporarily - an up-front error being preferable to a crash.)
	* c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
	(all actions): Adjust calls to pushlevel/poplevel.
	(parsing_iso_function_signature): Delete.
