In updating type information in r39026, I mistakenly used an unsigned type which we depended on rolling over to a negative value.  Rather than attempt to put an unsigned value into a signed variable and add casts everywhere, just use pointers (since that really what we're trying to emulate here), and be done with it.

    pointer comparisons.
