9384 (poplevel): Rename to pop_scope; totally rewritten for new bindings
9386 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
9387 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
9388 Improve some commentary. Adjust handling of forward parm decls.
9389 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
9390 Preserve C_DECL_IN_EXTERNAL_SCOPE.
9391 (warn_if_shadowing): Correct indentation. Improve diagnostics.

9393 decls. Rewrite for new bindings structures. Improve commentary.
9394 Eliminate the copy_node call.
9395 (implicit_decl_warning): Use the "diag" idiom (as seen in
9396 locate_old_decl) to reduce code duplication; call locate_old_decl

9412 First scope pushed is the external scope, not the global scope.

9456 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9457 correct loop over multiple translation units; call fatal_error if
9458 requested to compile more than one file at once. (This disables
9459 IMA temporarily - an up-front error being preferable to a crash.)
9460 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
9461 (all actions): Adjust calls to pushlevel/poplevel.
9462 (parsing_iso_function_signature): Delete.

9472 to suppress -Wold-style-definition after this error.
