I have tried without any of the options but it did not help.

May be that it inhibits finding with numeric tails but I have installed my files
with numeric tails disabled (~-) so that all files will be found. My djgpp
installation consists of the following packages:
acnf259b.zip, amak194b.zip, bnu223b.zip, bsh205bbr3.zip, bsn241b.zip,
byacc19b.zip, bz2-106a.zip, bz2-106b.zip, csdpmi7b.zip, dif32br3.zip,
djdev204.zip, djtzn204.zip, dosck11br2.zip, ed-15b.zip, faq230b.zip,
fil41b.zip, flx254b.zip, fnd4233br4.zip, gcc472b.zip, gdb75b.zip,
gdbm110br2.zip, gprf304b.zip, grep214b.zip, gro116b.zip, gwk401b.zip,
gzip15b.zip, h2m1371b.zip, isp3301b.zip, licv112b.zip, lss444b.zip,
lsupp64a.zip, m4-1415b.zip, mak381b.zip, man13b.zip, mktmp17br2.zip,
pat261b.zip, pcre831b.zip, pdcur34a.zip, perl588b.zip, rdln62b.zip,
sed421b.zip, shl2011b.zip, spl312br4.zip, tar112ab.zip, txi413br2.zip,
txt20b.zip, xz-504b.zip, dcrw853b.zip, jas1901b.zip, jbig20b.zip,
jpeg8db.zip, lcms23b.zip, lmpg051b.zip, mgrx100b.zip, png1510b.zip,
tiff401b.zip, zlib127b.zip
The only package that cannot be extracted without having numeric tail
generation enabled is perl, but here only certain man pages collide and I
do not care about this.  I prefer having numeric tail disabled.  The same
I do on my Win98SE installation.

I have tried the following versions.  I do not remember from where I downloaded
them.  I have only tested using djdev204, gcc472b and bnu223b:

03.07.2004  23:31            19.521 doslfn.com   from doslfnjh-0.33.zip   OK
28.11.2004  15:13            18.705 doslfn.com   from doslfn-0.40.zip     OK
01.03.2005  21:47            18.849 doslfn.com   from doslfn-0.40a.zip    OK
02.10.2006  12:41            18.902 doslfn.com   from doslfn-0.40e.zip    KO
16.12.2011  14:08            16.256 doslfn.com   from doslfn-0.41.zip     KO
05.01.2012  13:31            16.241 doslfn.com   from doslfn-0.41a.zip    KO
07.02.2012  16:43            16.317 doslfn.com   from doslfn-0.41b.zip    KO


 > Next, I'd try MS-DOS v7.10, if you have it.

I have tried Win98SE (I assume it is MS-DOS v7.10) with doslfn-0.41b and worked.

----------------- start -----------------
#include <stdio.h>

int main(int argc, char *argv[])
{
   int i;
   for (i = 0; i < argc; i++)
     printf("argv[%d]=%s\n", i, argv[i]);
   return i;
}
----------------- end -----------------

I have tried all option combinations but they did not work if DOSLFN did not
work with options.  Only those DOSLFN versions I have mentioned above did work
with MS-DOS 6.22.

2.04 should also work on plain DOS.  There is only a lack of interested
personnel to fix and implement missing features.
