I assume you're talking about IA-64 Windows.  But as I understand it,
long int is 32 bits on that platform, and off_t is 64 bits, so it's
not a problem.

The ftello substitute doesn't need to do anything special if long int
is narrower than off_t.  It needs to worry only if long int is wider
than off_t.
