    We can get a panic() call (and remove the ugly #ifdef's) with
    something like this:

    in some .h file:

    #ifdef DEVEXIT_LINKED
    #define DEVEXIT_FUNC(a) (a)
    #else
    void panic_exit_code();
    #define DEVEXIT_FUNC(a) ((typeof((a)) *)panic_exit_code)
    #endif

    in some .c file:

    #ifndef DEVEXIT_LINKED
    void panic_exit_code()
    {
    panic("__exit code called");
    }
    #endif


    change the drivers like this:

    #ifdef DEVEXIT_LINKED
    remove: firestream_remove_one,
    #endif

    to this:

    remove: DEVEXIT_FUNC(firestream_remove_one),
