1372 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
1373 First scope pushed is the external scope, not the global scope.
1374 (builtin_function): Use bind, not pushdecl. Adjust other bits
1375 for new data structures. Keep track of builtins that should be
1376 made visible automatically.
1377 (start_decl): Adjust diagnostics. Remove unnecessary call to
1379 (grokparms): Return 0 if arg_types is error_mark_node.
1380 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
1381 reversed sense. Rewrite for new bindings structures. Do not
1382 leave any decls in the scope, to prevent pop_scope from doing
1383 contradictory things with them.
1384 (finish_struct, finish_enum): Remove redundant diagnostics.
1385 (build_enumerator): Don't cascade diagnostics for error_mark_node.
1386 Mark location where -pedantic changes the meaning of the program.

1417 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
1418 correct loop over multiple translation units; call fatal_error if
1419 requested to compile more than one file at once. (This disables
1420 IMA temporarily - an up-front error being preferable to a crash.)
1421 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
1422 (all actions): Adjust calls to pushlevel/poplevel.
1423 (parsing_iso_function_signature): Delete.

1429 commented-out productions.

1431 an empty TREE_LIST node. Adjust calls to get_parm_info.
1432 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
1433 to suppress -Wold-style-definition after this error.
