Because there's no way of calling the NTFS file I/O routines from a
DOS program.  Well, not a documented and well-known way, at least.

DJGPP already supports 64-bit variables: there's the `long long' data
type which is 64-bit wide.

The problem is to use the 64-bit file I/O interface, which is
something very different, as so many people tried to explain in this
thread, from so many different angles.
