Yes - I was being lazy and wanted to set a counter to a very big
number and then replace it if any move to be rolled out needed to
start on an earlier game.

  int nFirstGame = ~0;

  loop over all moves {
        if (first game to roll out < nFirstGame)
            nFirstGame = first game to roll out
        other stuff
  }

but ~0 is a big int only for unsigned ints. Sigh.

I'm now doing another little change to text.c = it couldn't tell
Supremo from a user defined setting (the eval context matches World
Class, but the filters are different, the old code only found that the
eval context was World Class, then saw the filters were different and 
didn't examine Supremo.
