+       * eval.c (backtrace_function, backtrace_args): Now EXTERNALLY_VISIBLE.
+       This is for .gdbinit xbacktrace.
+
        * sysdep.c, term.c, termcap.c, terminal.c: Integer-related minor fixes.
        * sysdep.c (emacs_get_tty): Return void, since nobody uses the value.
        (emacs_set_tty): Now static.
