5879 c-common.c's pseudo-typedefs that wind up in the external scope.
5880 (lookup_name_current_level): Rename lookup_name_in_scope; take a
5881 second argument indicating the scope to examine; rewrite for
5882 new bindings structures.
5883 (c_init_decl_processing): Adjust for renamed functions. Do not
5884 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
5885 First scope pushed is the external scope, not the global scope.
5886 (builtin_function): Use bind, not pushdecl. Adjust other bits
5887 for new data structures. Keep track of builtins that should be
5888 made visible automatically.
5889 (start_decl): Adjust diagnostics. Remove unnecessary call to
5891 (grokparms): Return 0 if arg_types is error_mark_node.
5892 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
5893 reversed sense. Rewrite for new bindings structures. Do not

5895 contradictory things with them.
5896 (finish_struct, finish_enum): Remove redundant diagnostics.
5897 (build_enumerator): Don't cascade diagnostics for error_mark_node.
5898 Mark location where -pedantic changes the meaning of the program.
5899 (store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
5900 parameter decls into the function's scope structure using bind.

5904 function was defined with a prototype.
5905 (c_write_global_declarations): Operate on all file decls and on
5906 the external scope. Split body of the loop to...
5907 (c_write_global_declarations_1): ... this new function, to avoid

5928 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
5929 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
5930 correct loop over multiple translation units; call fatal_error if
5931 requested to compile more than one file at once. (This disables
5932 IMA temporarily - an up-front error being preferable to a crash.)
5933 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
5934 (all actions): Adjust calls to pushlevel/poplevel.
5935 (parsing_iso_function_signature): Delete.
5936 (extdef_1): Fold into extdef.
5937 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
5938 warn here about function definitions in the wrong style.

5940 (parm_declarator_nostarttypename, notype_declarator): Remove
5941 commented-out productions.
5942 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
5943 an empty TREE_LIST node. Adjust calls to get_parm_info.
5944 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
5945 to suppress -Wold-style-definition after this error.
5946 (c_parse_file): Don't clear the binding stack or call
5947 finish_fname_decls here. Correct comment.
5948 * c-typeck.c (same_translation_unit_p): Export.
