6400 (objc_mark_locals_volatile): Update for new bindings structures.
6401 (global_bindings_p): Honor c_override_global_bindings_to_false.
6402 (pushlevel): Rename to push_scope; take no arguments; use the
6403 scope_freelist; initialize scope->depth and check for overflow.
6404 (poplevel): Rename to pop_scope; totally rewritten for new bindings
6406 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
6407 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
6408 Improve some commentary. Adjust handling of forward parm decls.
6409 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
6410 Preserve C_DECL_IN_EXTERNAL_SCOPE.
6411 (warn_if_shadowing): Correct indentation. Improve diagnostics.

6414 Eliminate the copy_node call.
6415 (implicit_decl_warning): Use the "diag" idiom (as seen in
6416 locate_old_decl) to reduce code duplication; call locate_old_decl

6431 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
6432 First scope pushed is the external scope, not the global scope.

6439 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
6440 reversed sense. Rewrite for new bindings structures. Do not

6476 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
6477 correct loop over multiple translation units; call fatal_error if
6478 requested to compile more than one file at once. (This disables
6479 IMA temporarily - an up-front error being preferable to a crash.)
6480 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
6481 (all actions): Adjust calls to pushlevel/poplevel.

6492 to suppress -Wold-style-definition after this error.

11265 (_cpp_lex_direct): Use linemap_position_for_column.
11266 * c-ppoutput.c (maybe_print_line, print_line): Don't take map
