Sorry, *BSD supports it, Solaris supports it, MacOS supports it, I'm
fairly sure windows supports it, too..  So, MANY of the OSes out there
support it...  I can't claim that ALL the supported OSes have a native
64-bit integer type, but I would bet a dollar to a dime that a
majority of them do.

My confusion is about what AFS_64BIT_ENV actually signifies.  Does it
mean "we have a 64-bit integer type"?  Or "we support 64-bit file
lengths"?  Or "this is a native 64-bit OS?"  Or does it mean something
completely different?
