 Replying to [comment:2 QuLogic]:
 > So I haven't looked at everything, but I'm just wondering why in some
 places you replaced -1 with ~1, and in other places with ~0.

 Sorry, too quick with the send... They should be ~0, not ~1 in every case.
 The reason is that assiging -1 to an unsigned, such as size_t, results in
 a change of sign. Using ~0 has the same bit pattern, but is unsigned. I'll
 check all my changes and re-submit the patch.
