3254 (IDENTIFIER_LABEL_VALUE, C_DECL_INVISIBLE)
3255 (KEEP_NO, KEEP_YES, KEEP_MAYBE): Delete.
3256 (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.

3267 (poplevel): Rename to pop_scope; totally rewritten for new bindings
3269 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
3270 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
3271 Improve some commentary. Adjust handling of forward parm decls.
3272 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
3273 Preserve C_DECL_IN_EXTERNAL_SCOPE.
3274 (warn_if_shadowing): Correct indentation. Improve diagnostics.

3276 decls. Rewrite for new bindings structures. Improve commentary.
3277 Eliminate the copy_node call.
3278 (implicit_decl_warning): Use the "diag" idiom (as seen in
3279 locate_old_decl) to reduce code duplication; call locate_old_decl

3301 (grokparms): Return 0 if arg_types is error_mark_node.
3302 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
3303 reversed sense. Rewrite for new bindings structures. Do not
3304 leave any decls in the scope, to prevent pop_scope from doing
3305 contradictory things with them.
3306 (finish_struct, finish_enum): Remove redundant diagnostics.
3307 (build_enumerator): Don't cascade diagnostics for error_mark_node.

3339 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
3340 correct loop over multiple translation units; call fatal_error if
3341 requested to compile more than one file at once. (This disables
3342 IMA temporarily - an up-front error being preferable to a crash.)
3343 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
3344 (all actions): Adjust calls to pushlevel/poplevel.
3345 (parsing_iso_function_signature): Delete.
3346 (extdef_1): Fold into extdef.
3347 (old_style_parm_decls_1): Fold into old_style_parm_decls. Don't

3354 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
3355 to suppress -Wold-style-definition after this error.
3356 (c_parse_file): Don't clear the binding stack or call
3357 finish_fname_decls here. Correct comment.
3358 * c-typeck.c (same_translation_unit_p): Export.
