6349 (C_DECL_IN_EXTERNAL_SCOPE, C_DECL_DECLARED_BUILTIN): New.
6350 * c-common.h: Update prototypes.
6351 * c-decl.c (struct c_scope): Update commentary. Remove names,
6352 names_last, parms, parms_last, tags, and shadowed fields. Add

6360 (poplevel): Rename to pop_scope; totally rewritten for new bindings
6362 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
6363 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
6364 Improve some commentary. Adjust handling of forward parm decls.
6365 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
6366 Preserve C_DECL_IN_EXTERNAL_SCOPE.
6367 (warn_if_shadowing): Correct indentation. Improve diagnostics.
6368 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
6369 decls. Rewrite for new bindings structures. Improve commentary.
6370 Eliminate the copy_node call.
6371 (implicit_decl_warning): Use the "diag" idiom (as seen in
6372 locate_old_decl) to reduce code duplication; call locate_old_decl
6373 if appropriate. Relocate to remove need for forward declaration.
6374 (implicitly_declare): Adjust for new bindings structures. Kludge
6375 around Objective-C not-really-builtin functions.

6387 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
6388 First scope pushed is the external scope, not the global scope.

6392 (start_decl): Adjust diagnostics. Remove unnecessary call to
6394 (grokparms): Return 0 if arg_types is error_mark_node.
6395 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
6396 reversed sense. Rewrite for new bindings structures. Do not
6397 leave any decls in the scope, to prevent pop_scope from doing
6398 contradictory things with them.
6399 (finish_struct, finish_enum): Remove redundant diagnostics.
6400 (build_enumerator): Don't cascade diagnostics for error_mark_node.

6432 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
6433 correct loop over multiple translation units; call fatal_error if
6434 requested to compile more than one file at once. (This disables
6435 IMA temporarily - an up-front error being preferable to a crash.)
6436 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
6437 (all actions): Adjust calls to pushlevel/poplevel.
6438 (parsing_iso_function_signature): Delete.
6439 (extdef_1): Fold into extdef.

6447 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
6448 to suppress -Wold-style-definition after this error.
6449 (c_parse_file): Don't clear the binding stack or call
6450 finish_fname_decls here. Correct comment.
6451 * c-typeck.c (same_translation_unit_p): Export.
