3244 decls. Rewrite for new bindings structures. Improve commentary.
3245 Eliminate the copy_node call.
3246 (implicit_decl_warning): Use the "diag" idiom (as seen in
3247 locate_old_decl) to reduce code duplication; call locate_old_decl
3248 if appropriate. Relocate to remove need for forward declaration.
3249 (implicitly_declare): Adjust for new bindings structures. Kludge
3250 around Objective-C not-really-builtin functions.
3251 (undeclared_variable): Improve diagnostics. If current_function_decl
3252 is nonnull but current_function_scope is null, use current_scope.
3254 (lookup_tag): Adjust for new bindings structures. Kludge around
3255 Objective-C's tag declarations that wind up in the external scope.

3257 c-common.c's pseudo-typedefs that wind up in the external scope.
3258 (lookup_name_current_level): Rename lookup_name_in_scope; take a
3259 second argument indicating the scope to examine; rewrite for
3260 new bindings structures.
3261 (c_init_decl_processing): Adjust for renamed functions. Do not
3262 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
3263 First scope pushed is the external scope, not the global scope.
3264 (builtin_function): Use bind, not pushdecl. Adjust other bits
3265 for new data structures. Keep track of builtins that should be
3266 made visible automatically.
3267 (start_decl): Adjust diagnostics. Remove unnecessary call to
3269 (grokparms): Return 0 if arg_types is error_mark_node.
3270 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
3271 reversed sense. Rewrite for new bindings structures. Do not
3272 leave any decls in the scope, to prevent pop_scope from doing
3273 contradictory things with them.
3274 (finish_struct, finish_enum): Remove redundant diagnostics.
3275 (build_enumerator): Don't cascade diagnostics for error_mark_node.
3276 Mark location where -pedantic changes the meaning of the program.
3277 (store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
3278 parameter decls into the function's scope structure using bind.

3282 function was defined with a prototype.
3283 (c_write_global_declarations): Operate on all file decls and on
3284 the external scope. Split body of the loop to...

3306 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
3307 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
3308 correct loop over multiple translation units; call fatal_error if
3309 requested to compile more than one file at once. (This disables
3310 IMA temporarily - an up-front error being preferable to a crash.)
3311 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
3312 (all actions): Adjust calls to pushlevel/poplevel.
3313 (parsing_iso_function_signature): Delete.
3314 (extdef_1): Fold into extdef.
3315 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

3318 (parm_declarator_nostarttypename, notype_declarator): Remove
3319 commented-out productions.
3320 (parmlist_1, parmlist_2): Use make_node, not tree_cons, to create
3321 an empty TREE_LIST node. Adjust calls to get_parm_info.
3322 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
3323 to suppress -Wold-style-definition after this error.
3324 (c_parse_file): Don't clear the binding stack or call
3325 finish_fname_decls here. Correct comment.
3326 * c-typeck.c (same_translation_unit_p): Export.
