4497 * c-common.h: Update prototypes.
4498 * c-decl.c (struct c_scope): Update commentary. Remove names,
4499 names_last, parms, parms_last, tags, and shadowed fields. Add
4500 bindings and depth fields.
4501 (scope_freelist): Move to more appropriate location.
4502 (c_print_identifier): Update for changes to struct lang_identifier.
4503 (objc_mark_locals_volatile): Update for new bindings structures.
4504 (global_bindings_p): Honor c_override_global_bindings_to_false.
4505 (pushlevel): Rename to push_scope; take no arguments; use the
4506 scope_freelist; initialize scope->depth and check for overflow.
4507 (poplevel): Rename to pop_scope; totally rewritten for new bindings
4509 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
4510 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
4511 Improve some commentary. Adjust handling of forward parm decls.
4512 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
4513 Preserve C_DECL_IN_EXTERNAL_SCOPE.
4514 (warn_if_shadowing): Correct indentation. Improve diagnostics.
4515 (pushdecl): Remove unnecessary assertion. Short-circuit anonymous
4516 decls. Rewrite for new bindings structures. Improve commentary.
4517 Eliminate the copy_node call.
4518 (implicit_decl_warning): Use the "diag" idiom (as seen in
4519 locate_old_decl) to reduce code duplication; call locate_old_decl
4520 if appropriate. Relocate to remove need for forward declaration.
4521 (implicitly_declare): Adjust for new bindings structures. Kludge
4522 around Objective-C not-really-builtin functions.
4523 (undeclared_variable): Improve diagnostics. If current_function_decl
4524 is nonnull but current_function_scope is null, use current_scope.
4526 (lookup_tag): Adjust for new bindings structures. Kludge around
4527 Objective-C's tag declarations that wind up in the external scope.

4529 c-common.c's pseudo-typedefs that wind up in the external scope.
4530 (lookup_name_current_level): Rename lookup_name_in_scope; take a
4531 second argument indicating the scope to examine; rewrite for
4532 new bindings structures.
4533 (c_init_decl_processing): Adjust for renamed functions. Do not
4534 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
4535 First scope pushed is the external scope, not the global scope.
4536 (builtin_function): Use bind, not pushdecl. Adjust other bits
4537 for new data structures. Keep track of builtins that should be
4538 made visible automatically.
4539 (start_decl): Adjust diagnostics. Remove unnecessary call to
4541 (grokparms): Return 0 if arg_types is error_mark_node.
4542 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
4543 reversed sense. Rewrite for new bindings structures. Do not
4544 leave any decls in the scope, to prevent pop_scope from doing
4545 contradictory things with them.
4546 (finish_struct, finish_enum): Remove redundant diagnostics.
4547 (build_enumerator): Don't cascade diagnostics for error_mark_node.
4548 Mark location where -pedantic changes the meaning of the program.
4549 (store_parm_decls_newstyle, store_parm_decls_oldstyle): Load the
4550 parameter decls into the function's scope structure using bind.

4578 * c-opts.c (c_common_parse_file): Remove spurious ATTRIBUTE_UNUSED.
4579 Warn about YYDEBUG not being defined only if -dy. Remove no-longer-
4580 correct loop over multiple translation units; call fatal_error if
4581 requested to compile more than one file at once. (This disables
4582 IMA temporarily - an up-front error being preferable to a crash.)
4583 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
4584 (all actions): Adjust calls to pushlevel/poplevel.
4585 (parsing_iso_function_signature): Delete.
4586 (extdef_1): Fold into extdef.

4591 commented-out productions.

4593 an empty TREE_LIST node. Adjust calls to get_parm_info.
4594 (parmlist_2 : ELLIPSIS): Tag the arg-info block with error_mark_node
4595 to suppress -Wold-style-definition after this error.
4596 (c_parse_file): Don't clear the binding stack or call
4597 finish_fname_decls here. Correct comment.
4598 * c-typeck.c (same_translation_unit_p): Export.
4599 (common_type): Use c_override_global_bindings_to_false, not
4600 pushlevel/poplevel/declare_parm_level.
4601 * c-lang.c: Override LANG_HOOKS_CLEAR_BINDING_STACK,
4602 LANG_HOOKS_PUSHLEVEL, LANG_HOOKS_POPLEVEL, LANG_HOOKS_SET_BLOCK,
