Shouldn't the length of a range should be a long?Otherwise there's no way we could possibly replace streams with ranges. 32-bit systems have LOTS of common streams that are over 2^32 bytes (e.g. DVD images, partition images, large movies, etc.).
And not just that -- if we use size_t instead of long, bit arrays will only have a maximum length of 512 MiB -- waay lower than what 32-bit systems can handle.
