I'm afraid that my grey hairs give me an advantage here. You're missing my point; *there is no correct size*! In segmented memory models, the pointers are only offsets in the current segment; casting them to any integer type you choose simply will not work. Casting to size_t (or any other integral type large enough to hold the pointer) never gives any advantage over comparing the pointers directly.
