Don't use long for sizes. That's not what it is for, and it is quite
possible that on the 64-bit systems that are going to become common
soon objects can be larger than an unsigned long, let alone a signed
one.

Use size_t for the size of things, that is what it is for. There will
never be an implementation where an object will exist with a size too
large to fit into a size_t.
