8511 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
8512 Preserve C_DECL_IN_EXTERNAL_SCOPE.
8513 (warn_if_shadowing): Correct indentation. Improve diagnostics.
8514 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
8515 decls. Rewrite for new bindings structures. Improve commentary.
8516 Eliminate the copy_node call.
8517 (implicit_decl_warning): Use the "diag" idiom (as seen in
8518 locate_old_decl) to reduce code duplication; call locate_old_decl
8519 if appropriate. Relocate to remove need for forward declaration.
8520 (implicitly_declare): Adjust for new bindings structures. Kludge
8521 around Objective-C not-really-builtin functions.
8522 (undeclared_variable): Improve diagnostics. If current_function_decl
8523 is nonnull but current_function_scope is null, use current_scope.

8528 c-common.c's pseudo-typedefs that wind up in the external scope.
8529 (lookup_name_current_level): Rename lookup_name_in_scope; take a
8530 second argument indicating the scope to examine; rewrite for
8531 new bindings structures.
8532 (c_init_decl_processing): Adjust for renamed functions. Do not
8533 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
8534 First scope pushed is the external scope, not the global scope.
8535 (builtin_function): Use bind, not pushdecl. Adjust other bits
8536 for new data structures. Keep track of builtins that should be
8537 made visible automatically.
8538 (start_decl): Adjust diagnostics. Remove unnecessary call to
8540 (grokparms): Return 0 if arg_types is error_mark_node.
8541 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
8542 reversed sense. Rewrite for new bindings structures. Do not
8543 leave any decls in the scope, to prevent pop_scope from doing
8544 contradictory things with them.
8545 (finish_struct, finish_enum): Remove redundant diagnostics.
8546 (build_enumerator): Don't cascade diagnostics for error_mark_node.
8547 Mark location where -pedantic changes the meaning of the program.

8577 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
8578 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
8579 correct loop over multiple translation units; call fatal_error if
8580 requested to compile more than one file at once. (This disables
8581 IMA temporarily - an up-front error being preferable to a crash.)
8582 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
8583 (all actions): Adjust calls to pushlevel/poplevel.
8584 (parsing_iso_function_signature): Delete.
8585 (extdef_1): Fold into extdef.

8590 commented-out productions.

8592 an empty TREE_LIST node. Adjust calls to get_parm_info.
8593 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
8594 to suppress -Wold-style-definition after this error.
8595 (c_parse_file): Don't clear the binding stack or call
8596 finish_fname_decls here. Correct comment.
8597 * c-typeck.c (same_translation_unit_p): Export.

13366 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
13367 (_cpp_lex_direct): Use linemap_position_for_column.
13368 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
