    Even better.

    That way you can actually totally remove the "verbose bug" config option,
    because even the verbose BUG's aren't actually using up any noticeable
    amounts of space.

    This is all assuming that gcc doesn't create the string for inline
    functions that aren't used, which it probably cannot, so maybe this
    doesn't work out.
