I expect the bug is in this API call.  DJGPP has heavily used
and tested it's API over the last 15 years.  On the other hand,
the API to get file lengths over 2GB is very rarely used and
very likely to be buggy given the various combinations of
drivers and DOS versions.

I think your patch is a good one.

While v2.03 was tested in all environments, v2.04 has had
very sparse testing on non-XP environments.
