I have found my old FreeDOS CD and installed DOSLFN 0.40c.
With this driver everthing works on MSDOS.  Stepping into
the filelength() code shows that the 0.40e version does
not set the CF when it returns from 0x71A6 call while 0.40c
does so that it jumps directly into the 0x4201 code instead
of returning an EOVERFLOW.
Neitherless, the points that were pointed out by Charles
Sandmann in
http://www.delorie.com/archives/browse.cgi?p=djgpp/2011/09/02/23:45:11
still are open.  Some fix for that issue would be nice.
