3247 (c_print_identifier): Update for changes to struct lang_identifier.
3248 (objc_mark_locals_volatile): Update for new bindings structures.
3249 (global_bindings_p): Honor c_override_global_bindings_to_false.

3251 scope_freelist; initialize scope->depth and check for overflow.
3252 (poplevel): Rename to pop_scope; totally rewritten for new bindings
3254 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
3255 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
3256 Improve some commentary. Adjust handling of forward parm decls.
3257 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
3258 Preserve C_DECL_IN_EXTERNAL_SCOPE.
3259 (warn_if_shadowing): Correct indentation. Improve diagnostics.
3260 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
3261 decls. Rewrite for new bindings structures. Improve commentary.
3262 Eliminate the copy_node call.
3263 (implicit_decl_warning): Use the "diag" idiom (as seen in
3264 locate_old_decl) to reduce code duplication; call locate_old_decl
3265 if appropriate. Relocate to remove need for forward declaration.
3266 (implicitly_declare): Adjust for new bindings structures. Kludge
3267 around Objective-C not-really-builtin functions.

3279 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
3280 First scope pushed is the external scope, not the global scope.

3286 (grokparms): Return 0 if arg_types is error_mark_node.
3287 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
3288 reversed sense. Rewrite for new bindings structures. Do not
3289 leave any decls in the scope, to prevent pop_scope from doing
3290 contradictory things with them.
3291 (finish_struct, finish_enum): Remove redundant diagnostics.
3292 (build_enumerator): Don't cascade diagnostics for error_mark_node.
3293 Mark location where -pedantic changes the meaning of the program.

3324 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
3325 correct loop over multiple translation units; call fatal_error if
3326 requested to compile more than one file at once. (This disables
3327 IMA temporarily - an up-front error being preferable to a crash.)
3328 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
3329 (all actions): Adjust calls to pushlevel/poplevel.
3330 (parsing_iso_function_signature): Delete.

3340 to suppress -Wold-style-definition after this error.
3341 (c_parse_file): Don't clear the binding stack or call
3342 finish_fname_decls here. Correct comment.
3343 * c-typeck.c (same_translation_unit_p): Export.
