41 bindings and depth fields.
42 (scope_freelist): Move to more appropriate location.
43 (c_print_identifier): Update for changes to struct lang_identifier.
44 (objc_mark_locals_volatile): Update for new bindings structures.
45 (global_bindings_p): Honor c_override_global_bindings_to_false.

48 (poplevel): Rename to pop_scope; totally rewritten for new bindings
50 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
51 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
52 Improve some commentary. Adjust handling of forward parm decls.
53 (merge_decls): Set C_DECL_DECLARED_BUILTIN when appropriate.
54 Preserve C_DECL_IN_EXTERNAL_SCOPE.

57 decls. Rewrite for new bindings structures. Improve commentary.
58 Eliminate the copy_node call.
59 (implicit_decl_warning): Use the "diag" idiom (as seen in
60 locate_old_decl) to reduce code duplication; call locate_old_decl
61 if appropriate. Relocate to remove need for forward declaration.
62 (implicitly_declare): Adjust for new bindings structures. Kludge
63 around Objective-C not-really-builtin functions.
64 (undeclared_variable): Improve diagnostics. If current_function_decl
65 is nonnull but current_function_scope is null, use current_scope.
67 (lookup_tag): Adjust for new bindings structures. Kludge around
68 Objective-C's tag declarations that wind up in the external scope.
69 (lookup_name): Adjust for new bindings structures. Kludge around
70 c-common.c's pseudo-typedefs that wind up in the external scope.

78 for new data structures. Keep track of builtins that should be
79 made visible automatically.

83 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with
84 reversed sense. Rewrite for new bindings structures. Do not
85 leave any decls in the scope, to prevent pop_scope from doing
86 contradictory things with them.

122 requested to compile more than one file at once. (This disables
123 IMA temporarily - an up-front error being preferable to a crash.)
