4497 (scope_freelist): Move to more appropriate location.
4498 (c_print_identifier): Update for changes to struct lang_identifier.
4499 (objc_mark_locals_volatile): Update for new bindings structures.
4500 (global_bindings_p): Honor c_override_global_bindings_to_false.
4501 (pushlevel): Rename to push_scope; take no arguments; use the
4502 scope_freelist; initialize scope->depth and check for overflow.
4503 (poplevel): Rename to pop_scope; totally rewritten for new bindings
4505 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
4506 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
4507 Improve some commentary. Adjust handling of forward parm decls.
4508 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
4509 Preserve C_DECL_IN_EXTERNAL_SCOPE.
4510 (warn_if_shadowing): Correct indentation. Improve diagnostics.
4511 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
4512 decls. Rewrite for new bindings structures. Improve commentary.
4513 Eliminate the copy_node call.
4514 (implicit_decl_warning): Use the "diag" idiom (as seen in
4515 locate_old_decl) to reduce code duplication; call locate_old_decl
4516 if appropriate. Relocate to remove need for forward declaration.
4517 (implicitly_declare): Adjust for new bindings structures. Kludge
4518 around Objective-C not-really-builtin functions.
4519 (undeclared_variable): Improve diagnostics. If current_function_decl

4530 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
4531 First scope pushed is the external scope, not the global scope.

4535 (start_decl): Adjust diagnostics. Remove unnecessary call to
4537 (grokparms): Return 0 if arg_types is error_mark_node.
4538 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
4539 reversed sense. Rewrite for new bindings structures. Do not
4540 leave any decls in the scope, to prevent pop_scope from doing
4541 contradictory things with them.
4542 (finish_struct, finish_enum): Remove redundant diagnostics.
4543 (build_enumerator): Don't cascade diagnostics for error_mark_node.
4544 Mark location where -pedantic changes the meaning of the program.

4546 parameter decls into the function's scope structure using bind.

4575 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
4576 correct loop over multiple translation units; call fatal_error if
4577 requested to compile more than one file at once. (This disables
4578 IMA temporarily - an up-front error being preferable to a crash.)
4579 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
4580 (all actions): Adjust calls to pushlevel/poplevel.
4581 (parsing_iso_function_signature): Delete.

4590 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
4591 to suppress -Wold-style-definition after this error.
4592 (c_parse_file): Don't clear the binding stack or call
4593 finish_fname_decls here. Correct comment.
4594 * c-typeck.c (same_translation_unit_p): Export.
