38 (c_print_identifier): Update for changes to struct lang_identifier.
39 (objc_mark_locals_volatile): Update for new bindings structures.
40 (global_bindings_p): Honor c_override_global_bindings_to_false.

43 (poplevel): Rename to pop_scope; totally rewritten for new bindings
45 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
46 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.

58 around Objective-C not-really-builtin functions.
59 (undeclared_variable): Improve diagnostics. If current_function_decl
60 is nonnull but current_function_scope is null, use current_scope.
62 (lookup_tag): Adjust for new bindings structures. Kludge around

81 contradictory things with them.

117 requested to compile more than one file at once. (This disables
118 IMA temporarily - an up-front error being preferable to a crash.)
119 * c-parse.in (pushlevel, poplevel rules): Rename push_scope, pop_scope.
