7675 (c_print_identifier): Update for changes to struct lang_identifier.
7676 (objc_mark_locals_volatile): Update for new bindings structures.
7677 (global_bindings_p): Honor c_override_global_bindings_to_false.

7679 scope_freelist; initialize scope->depth and check for overflow.
7680 (poplevel): Rename to pop_scope; totally rewritten for new bindings
7682 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
7683 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
7684 Improve some commentary. Adjust handling of forward parm decls.
7685 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
7686 Preserve C_DECL_IN_EXTERNAL_SCOPE.
7687 (warn_if_shadowing): Correct indentation. Improve diagnostics.
7688 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
7689 decls. Rewrite for new bindings structures. Improve commentary.
7690 Eliminate the copy_node call.
7691 (implicit_decl_warning): Use the "diag" idiom (as seen in
7692 locate_old_decl) to reduce code duplication; call locate_old_decl
7693 if appropriate. Relocate to remove need for forward declaration.
7694 (implicitly_declare): Adjust for new bindings structures. Kludge
7695 around Objective-C not-really-builtin functions.

7707 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
7708 First scope pushed is the external scope, not the global scope.

7712 (start_decl): Adjust diagnostics. Remove unnecessary call to
7714 (grokparms): Return 0 if arg_types is error_mark_node.
7715 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
7716 reversed sense. Rewrite for new bindings structures. Do not
7717 leave any decls in the scope, to prevent pop_scope from doing
7718 contradictory things with them.
7719 (finish_struct, finish_enum): Remove redundant diagnostics.
7720 (build_enumerator): Don't cascade diagnostics for error_mark_node.
7721 Mark location where -pedantic changes the meaning of the program.

7752 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
7753 correct loop over multiple translation units; call fatal_error if
7754 requested to compile more than one file at once. (This disables
7755 IMA temporarily - an up-front error being preferable to a crash.)
7756 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
7757 (all actions): Adjust calls to pushlevel/poplevel.
7758 (parsing_iso_function_signature): Delete.

7767 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
7768 to suppress -Wold-style-definition after this error.
7769 (c_parse_file): Don't clear the binding stack or call
7770 finish_fname_decls here. Correct comment.
7771 * c-typeck.c (same_translation_unit_p): Export.

12540 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
12541 (_cpp_lex_direct): Use linemap_position_for_column.
12542 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
12543 parameter. Instead get it from the line_table global. Adjust callers.
