953 (objc_mark_locals_volatile): Update for new bindings structures.
954 (global_bindings_p): Honor c_override_global_bindings_to_false.
955 (pushlevel): Rename to push_scope; take no arguments; use the

957 (poplevel): Rename to pop_scope; totally rewritten for new bindings
959 (diagnose_mismatched_decls): Use C_DECL_DECLARED_BUILTIN, not
960 C_DECL_INVISIBLE, for certain decisions. Adjust some diagnostics.
961 Improve some commentary. Adjust handling of forward parm decls.

984 initialize current_file_decl, first_builtin_decl, last_builtin_decl.
985 First scope pushed is the external scope, not the global scope.

987 for new data structures. Keep track of builtins that should be

992 (get_parm_info): Rename "void_at_end" argument to "ellipsis", with

1031 requested to compile more than one file at once. (This disables
