thanks for the patches! I've checked them in. I believe it would be 
better to fix sign compare problems by changing the types involved to a 
more reasonable one where possible, but I didn't investigate if it was 
possible in this case.

Ignoring confusing warnings sounds like a good policy. I've talked to 
Adam about it, and we've agreed to leave it enabled since it should help 
us pinpoint failures on 64 bit systems, and similar beasts.

keep up the good work,
