I might be wrong here, but doesn't that go against the C standard?
Shouldn't long be (at least) 64 bits on a 64-bit platform? I thought
ANSI C guaranteed that a pointer should fit inside a long. If that's not
the case this might be a huge portability problem then 64-bit platforms
become more common.
