OK, strictly I guess there should be some (void) casts in a number of
function calls. Looks like your compiler has turned on some even more
agressive warning options. I'll see if I can do something about this.
Certainly those warnings don't indicate that anything will go wrong.

That looks like the BDB 4.3 API change problem which was posted on the
list not too long ago. It will be fixed in 4.52, which I'm going to get
out before the end of the month. If you can't wait, the patch is below.
