1426 (poplevel): Rename to pop_scope; totally rewritten for new bindings

1429 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
1430 Improve some commentary. Adjust handling of forward parm decls.
1431 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
1432 Preserve C_DECL_IN_EXTERNAL_SCOPE.
1433 (warn_if_shadowing): Correct indentation. Improve diagnostics.

1436 Eliminate the copy_node call.

1453 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1454 First scope pushed is the external scope, not the global scope.

1498 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1499 correct loop over multiple translation units; call fatal_error if
1500 requested to compile more than one file at once. (This disables
1501 IMA temporarily - an up-front error being preferable to a crash.)
1502 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1503 (all actions): Adjust calls to pushlevel/poplevel.
1504 (parsing_iso_function_signature): Delete.

1514 to suppress -Wold-style-definition after this error.
