The reason is that you need 32bit versions when you want to keep binary
compatibility within e.g. libc. off_t can be 32bit and 64bit and moving
to 64bit can be done by either:
(1) Introduction of a new type and new functions, keeping the default as
it was. This happened on Solaris and Linux.
(2) Introduce a new libc major version (requiring a rebuild of
everything) and make the 32bit compatibility system calls only. This is
what happened on the BSDs and which removes a lot of hassles. Using
stuff like stat64 is evil and NEVER be done.
