Sorry for having been  imprecise.  I usualy do not use djgpp 2.03
anymore
so I did not note that the gcc version compiled with 2.03 worked.
Yes, you are right, the problem is only with 2.04's  `filelength' and
`lfilelength'.
Both use 71A6 and fail with EOVERFLOW under certain circunstances.
The only thing we need to do is to fix both functions so they work
like
the 2.03 versions if the 71A6 call fails with EOVERFLOW.
