I'm not in favor of the llabs() changes. I think what we really want
in those places, or at least most of them, is "abs() for int64".
That could be had by #define'ing "iabs64" (or some name along that
line) as labs or llabs depending on which type we are using for int64.
Seems OK beyond that nitpick.
