=====================================

Would the above code make any difference cross-platform? Is size_t as fast (cross-platform) as the above typedef?

I believe that the above code converts whatever size_t is defined as into something that is 'fast'- the easiest for the processor to manipulate. However, what I don't know is whether size_t is already that.

It's highly unlikely that fsize_t is different from size_t. (It might be a different type with the same size, but that won't affect performance).

Also, I noticed that boost::hash returns 'size_t' so was just wondering why. I will be using hashes in different collections so had tried (above) to store them using the 'fast' boost::integer form.
