8503 c-common.c's pseudo-typedefs that wind up in the external scope.
8504 (lookup_name_current_level): Rename lookup_name_in_scope; take a
8505 second argument indicating the scope to examine; rewrite for
8506 new bindings structures.
8507 (c_init_decl_processing): Adjust for renamed functions. Do not
8508 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
8509 First scope pushed is the external scope, not the global scope.
8510 (builtin_function): Use bind, not pushdecl. Adjust other bits
8511 for new data structures. Keep track of builtins that should be
8512 made visible automatically.

8515 (grokparms): Return 0 if arg_types is error_mark_node.
8516 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
8517 reversed sense. Rewrite for new bindings structures. Do not

8519 contradictory things with them.
8520 (finish_struct, finish_enum): Remove redundant diagnostics.
8521 (build_enumerator): Don't cascade diagnostics for error_mark_node.
8522 Mark location where -pedantic changes the meaning of the program.
8523 (store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
8524 parameter decls into the function's scope structure using bind.

8528 function was defined with a prototype.
8529 (c_write_global_declarations): Operate on all file decls and on
8530 the external scope. Split body of the loop to...

8552 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
8553 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
8554 correct loop over multiple translation units; call fatal_error if
8555 requested to compile more than one file at once. (This disables
8556 IMA temporarily - an up-front error being preferable to a crash.)
8557 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
8558 (all actions): Adjust calls to pushlevel/poplevel.
8559 (parsing_iso_function_signature): Delete.
8560 (extdef_1): Fold into extdef.
8561 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

8564 (parm_declarator_nostarttypename, notype_declarator): Remove
8565 commented-out productions.
8566 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
8567 an empty TREE_LIST node. Adjust calls to get_parm_info.
8568 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
8569 to suppress -Wold-style-definition after this error.
8570 (c_parse_file): Don't clear the binding stack or call
8571 finish_fname_decls here. Correct comment.
8572 * c-typeck.c (same_translation_unit_p): Export.

13341 (_cpp_get_fresh_line): Don't need to adjust line for missing newline.
13342 (_cpp_lex_direct): Use linemap_position_for_column.
13343 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
