5878 (implicit_decl_warning): Use the "diag" idiom (as seen in
5879 locate_old_decl) to reduce code duplication; call locate_old_decl
5880 if appropriate. Relocate to remove need for forward declaration.
5881 (implicitly_declare): Adjust for new bindings structures. Kludge
5882 around Objective-C not-really-builtin functions.
5883 (undeclared_variable): Improve diagnostics. If current_function_decl
5884 is nonnull but current_function_scope is null, use current_scope.
5886 (lookup_tag): Adjust for new bindings structures. Kludge around
5887 Objective-C's tag declarations that wind up in the external scope.
5888 (lookup_name): Adjust for new bindings structures. Kludge around
5889 c-common.c's pseudo-typedefs that wind up in the external scope.
5890 (lookup_name_current_level): Rename lookup_name_in_scope; take a
5891 second argument indicating the scope to examine; rewrite for
5892 new bindings structures.
5893 (c_init_decl_processing): Adjust for renamed functions. Do not
5894 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
5895 First scope pushed is the external scope, not the global scope.
5896 (builtin_function): Use bind, not pushdecl. Adjust other bits
5897 for new data structures. Keep track of builtins that should be
5898 made visible automatically.
5899 (start_decl): Adjust diagnostics. Remove unnecessary call to
5901 (grokparms): Return 0 if arg_types is error_mark_node.
5902 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
5903 reversed sense. Rewrite for new bindings structures. Do not
5904 leave any decls in the scope, to prevent pop_scope from doing
5905 contradictory things with them.
5906 (finish_struct, finish_enum): Remove redundant diagnostics.
5907 (build_enumerator): Don't cascade diagnostics for error_mark_node.
5908 Mark location where -pedantic changes the meaning of the program.

5910 parameter decls into the function's scope structure using bind.

5914 function was defined with a prototype.
5915 (c_write_global_declarations): Operate on all file decls and on
5916 the external scope. Split body of the loop to...

5938 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
5939 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
5940 correct loop over multiple translation units; call fatal_error if
5941 requested to compile more than one file at once. (This disables
5942 IMA temporarily - an up-front error being preferable to a crash.)
5943 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
5944 (all actions): Adjust calls to pushlevel/poplevel.
5945 (parsing_iso_function_signature): Delete.
5946 (extdef_1): Fold into extdef.
5947 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

5950 (parm_declarator_nostarttypename, notype_declarator): Remove
5951 commented-out productions.
5952 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
5953 an empty TREE_LIST node. Adjust calls to get_parm_info.
5954 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
5955 to suppress -Wold-style-definition after this error.
5956 (c_parse_file): Don't clear the binding stack or call
5957 finish_fname_decls here. Correct comment.
5958 * c-typeck.c (same_translation_unit_p): Export.
