9332 (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
9333 * c-common.h: Update prototypes.
9334 * c-decl.c (struct c_scope): Update commentary. Remove names,

9343 (poplevel): Rename to pop_scope; totally rewritten for new bindings
9345 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
9346 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
9347 Improve some commentary. Adjust handling of forward parm decls.
9348 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
9349 Preserve C_DECL_IN_EXTERNAL_SCOPE.
9350 (warn_if_shadowing): Correct indentation. Improve diagnostics.
9351 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
9352 decls. Rewrite for new bindings structures. Improve commentary.
9353 Eliminate the copy_node call.
9354 (implicit_decl_warning): Use the "diag" idiom (as seen in
9355 locate_old_decl) to reduce code duplication; call locate_old_decl
9356 if appropriate. Relocate to remove need for forward declaration.
9357 (implicitly_declare): Adjust for new bindings structures. Kludge
9358 around Objective-C not-really-builtin functions.

9370 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
9371 First scope pushed is the external scope, not the global scope.

9377 (grokparms): Return 0 if arg_types is error_mark_node.
9378 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
9379 reversed sense. Rewrite for new bindings structures. Do not
9380 leave any decls in the scope, to prevent pop_scope from doing
9381 contradictory things with them.
9382 (finish_struct, finish_enum): Remove redundant diagnostics.
9383 (build_enumerator): Don't cascade diagnostics for error_mark_node.

9415 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
9416 correct loop over multiple translation units; call fatal_error if
9417 requested to compile more than one file at once. (This disables
9418 IMA temporarily - an up-front error being preferable to a crash.)
9419 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
9420 (all actions): Adjust calls to pushlevel/poplevel.
9421 (parsing_iso_function_signature): Delete.
9422 (extdef_1): Fold into extdef.

9430 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
9431 to suppress -Wold-style-definition after this error.
9432 (c_parse_file): Don't clear the binding stack or call
9433 finish_fname_decls here. Correct comment.
9434 * c-typeck.c (same_translation_unit_p): Export.
