2317 (implicit_decl_warning): Use the "diag" idiom (as seen in
2318 locate_old_decl) to reduce code duplication; call locate_old_decl
2319 if appropriate. Relocate to remove need for forward declaration.
2320 (implicitly_declare): Adjust for new bindings structures. Kludge
2321 around Objective-C not-really-builtin functions.
2322 (undeclared_variable): Improve diagnostics. If current_function_decl
2323 is nonnull but current_function_scope is null, use current_scope.
2325 (lookup_tag): Adjust for new bindings structures. Kludge around
2326 Objective-C's tag declarations that wind up in the external scope.

2328 c-common.c's pseudo-typedefs that wind up in the external scope.
2329 (lookup_name_current_level): Rename lookup_name_in_scope; take a
2330 second argument indicating the scope to examine; rewrite for
2331 new bindings structures.
2332 (c_init_decl_processing): Adjust for renamed functions. Do not
2333 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
2334 First scope pushed is the external scope, not the global scope.
2335 (builtin_function): Use bind, not pushdecl. Adjust other bits
2336 for new data structures. Keep track of builtins that should be
2337 made visible automatically.
2338 (start_decl): Adjust diagnostics. Remove unnecessary call to
2340 (grokparms): Return 0 if arg_types is error_mark_node.
2341 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
2342 reversed sense. Rewrite for new bindings structures. Do not
2343 leave any decls in the scope, to prevent pop_scope from doing
2344 contradictory things with them.
2345 (finish_struct, finish_enum): Remove redundant diagnostics.
2346 (build_enumerator): Don't cascade diagnostics for error_mark_node.
2347 Mark location where -pedantic changes the meaning of the program.

2355 the external scope. Split body of the loop to...

2377 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
2378 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
2379 correct loop over multiple translation units; call fatal_error if
2380 requested to compile more than one file at once. (This disables
2381 IMA temporarily - an up-front error being preferable to a crash.)
2382 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
2383 (all actions): Adjust calls to pushlevel/poplevel.
2384 (parsing_iso_function_signature): Delete.
2385 (extdef_1): Fold into extdef.
2386 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

2389 (parm_declarator_nostarttypename, notype_declarator): Remove
2390 commented-out productions.
2391 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
2392 an empty TREE_LIST node. Adjust calls to get_parm_info.
2393 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
2394 to suppress -Wold-style-definition after this error.
2395 (c_parse_file): Don't clear the binding stack or call
2396 finish_fname_decls here. Correct comment.
2397 * c-typeck.c (same_translation_unit_p): Export.
