6340 (implicit_decl_warning): Use the "diag" idiom (as seen in
6341 locate_old_decl) to reduce code duplication; call locate_old_decl
6342 if appropriate. Relocate to remove need for forward declaration.
6343 (implicitly_declare): Adjust for new bindings structures. Kludge
6344 around Objective-C not-really-builtin functions.
6345 (undeclared_variable): Improve diagnostics. If current_function_decl
6346 is nonnull but current_function_scope is null, use current_scope.
6348 (lookup_tag): Adjust for new bindings structures. Kludge around
6349 Objective-C's tag declarations that wind up in the external scope.
6350 (lookup_name): Adjust for new bindings structures. Kludge around
6351 c-common.c's pseudo-typedefs that wind up in the external scope.
6352 (lookup_name_current_level): Rename lookup_name_in_scope; take a
6353 second argument indicating the scope to examine; rewrite for
6354 new bindings structures.
6355 (c_init_decl_processing): Adjust for renamed functions. Do not
6356 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
6357 First scope pushed is the external scope, not the global scope.
6358 (builtin_function): Use bind, not pushdecl. Adjust other bits
6359 for new data structures. Keep track of builtins that should be
6360 made visible automatically.
6361 (start_decl): Adjust diagnostics. Remove unnecessary call to
6363 (grokparms): Return 0 if arg_types is error_mark_node.
6364 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
6365 reversed sense. Rewrite for new bindings structures. Do not
6366 leave any decls in the scope, to prevent pop_scope from doing
6367 contradictory things with them.
6368 (finish_struct, finish_enum): Remove redundant diagnostics.
6369 (build_enumerator): Don't cascade diagnostics for error_mark_node.
6370 Mark location where -pedantic changes the meaning of the program.

6372 parameter decls into the function's scope structure using bind.

6376 function was defined with a prototype.
6377 (c_write_global_declarations): Operate on all file decls and on
6378 the external scope. Split body of the loop to...

6400 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
6401 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
6402 correct loop over multiple translation units; call fatal_error if
6403 requested to compile more than one file at once. (This disables
6404 IMA temporarily - an up-front error being preferable to a crash.)
6405 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
6406 (all actions): Adjust calls to pushlevel/poplevel.
6407 (parsing_iso_function_signature): Delete.
6408 (extdef_1): Fold into extdef.
6409 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't
6410 warn here about function definitions in the wrong style.

6412 (parm_declarator_nostarttypename, notype_declarator): Remove
6413 commented-out productions.
6414 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
6415 an empty TREE_LIST node. Adjust calls to get_parm_info.
6416 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
6417 to suppress -Wold-style-definition after this error.
6418 (c_parse_file): Don't clear the binding stack or call
6419 finish_fname_decls here. Correct comment.
6420 * c-typeck.c (same_translation_unit_p): Export.

12044 Partially revert/redo 2003-10-01 change; fix -fworking-directory.
12045 * c-ppoutput.c (pp_dir_change): New function.
12046 * c-common.h (pp_dir_change): New declaration.
12047 * cpplib.h (struct cpp_options): Remove working_directory field.
12048 * cppinit.c (cpp_find_main_file, cpp_push_main_file): Merge back to
12049 (cpp_read_main_file): as before 10-01. Call _cpp_stack_file.
12050 Don't handle -fworking_directory here, but in c_common_post_options.
12051 (read_original_directory): Don't back up when done.
12052 Don't clear no-longer used working_directory flag.
12053 * cpplib.h: Update declarations to match.
12054 * c-lex.c (cb_dir_change): Move to c-opts.c.
12055 (init_c_lex): Don't set dir_change callback here, since we want
12056 to set it even if flag_preprocess_only.
12057 * c-opts.c (cb_dir_change): Function moved from c-lex.c.
12058 (c_common_post_options): Set dir_change callback.
12059 Call pp_dir_change if approporiate.
12060 (finish_options): Don't call cpp_find_main_file here. Hence remove
12061 unneeded parameter and result. Do LC_RENAME for <built-in>.
12062 (c_common_post_options): Call cpp_read_main_file here instead.
12063 (c_common_init): Update accordingly.
12064 (push_command_line_include): Don't cpp_push_main_file.
12065 Do LC_RENAME rather than LC_LEASE to get back to main file.
12066 Compared to pre-10-01 version, inline cpp_rename_to_main_file.
12067 (c_common_parse_file): Call cpp_read_main_file for subsequent main
12068 files, but call finish_options for all files.
12069 * c-opts.c (sanitize_cpp_opts): Don't set cpp_opts->working_directory.
12070 * fix-header.c (read_scan_file): Call cpp_read_main_file instead of
12071 cpp_find_main_file + cpp_push_main_file.
12072 * c-lex.c (fe_file_change): Don't set main_input_filename here.
12073 * opts.c (handle_options): Only set main_input_filename first time.
