Using new gcc 4.0 I have some serios warnings about uninitialized
variables, that are used. I created a patch, but I have no idea if it
is possible to do it my way. Can you check this out please?


Erik: I've modified the patch slightly based on the contents of an older
      version of hitlist.cxx. I think this is correct now.
