7270 (implicit_decl_warning): Use the "diag" idiom (as seen in
7271 locate_old_decl) to reduce code duplication; call locate_old_decl
7272 if appropriate. Relocate to remove need for forward declaration.
7273 (implicitly_declare): Adjust for new bindings structures. Kludge
7274 around Objective-C not-really-builtin functions.
7275 (undeclared_variable): Improve diagnostics. If current_function_decl
7276 is nonnull but current_function_scope is null, use current_scope.
7278 (lookup_tag): Adjust for new bindings structures. Kludge around
7279 Objective-C's tag declarations that wind up in the external scope.

7281 c-common.c's pseudo-typedefs that wind up in the external scope.
7282 (lookup_name_current_level): Rename lookup_name_in_scope; take a
7283 second argument indicating the scope to examine; rewrite for
7284 new bindings structures.
7285 (c_init_decl_processing): Adjust for renamed functions. Do not
7286 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
7287 First scope pushed is the external scope, not the global scope.
7288 (builtin_function): Use bind, not pushdecl. Adjust other bits
7289 for new data structures. Keep track of builtins that should be
7290 made visible automatically.
7291 (start_decl): Adjust diagnostics. Remove unnecessary call to
7293 (grokparms): Return 0 if arg_types is error_mark_node.
7294 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
7295 reversed sense. Rewrite for new bindings structures. Do not
7296 leave any decls in the scope, to prevent pop_scope from doing
7297 contradictory things with them.
7298 (finish_struct, finish_enum): Remove redundant diagnostics.
7299 (build_enumerator): Don't cascade diagnostics for error_mark_node.
7300 Mark location where -pedantic changes the meaning of the program.

7330 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
7331 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
7332 correct loop over multiple translation units; call fatal_error if
7333 requested to compile more than one file at once. (This disables
7334 IMA temporarily - an up-front error being preferable to a crash.)
7335 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
7336 (all actions): Adjust calls to pushlevel/poplevel.
7337 (parsing_iso_function_signature): Delete.
7338 (extdef_1): Fold into extdef.
7339 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

7343 commented-out productions.

7345 an empty TREE_LIST node. Adjust calls to get_parm_info.
7346 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
7347 to suppress -Wold-style-definition after this error.
7348 (c_parse_file): Don't clear the binding stack or call
7349 finish_fname_decls here. Correct comment.
7350 * c-typeck.c (same_translation_unit_p): Export.
