That's true, but 64 bit will affect other things as well - pointer size goes up, your stack will be bigger and the packing (alignment) of your structures change

If your compiler is unfriendly, your structure size can change significantly -- afaik, GCC is pretty clever about structure packing, but I'd imagine it varies a lot depending on the architecture.
