    [PATCH] PR modula2/108344 disable default opening of /dev/tty

    This patch changes removes the static initialisation code for
    KeyBoardLEDs.cc.  The module is only initialised if one of the
    exported functions is called.  This is useful as the module will
    access /dev/tty which might not be available.  TimerHandler.mod has
    also been changed to disable the scroll lock LED as a sign of life.
