I have been able to cross-compile gnuchess 5.05.
Version 5 was released in 1999:
Announce: https://www.tim-mann.org/gnuchess/5.00.txt
According to:
https://www.tim-mann.org/gnuchess.html
version 6 was released in 2011
So that version, 5.05 does not use pthread, and is easier to compile.
Mostly had done:
[I have also added libreadline from
http://www.delorie.com/pub/djgpp/current/v2gnu/rdln80b.zip to my
cross-compiler.]
./configure --host=i386-pc-msdosdjgpp
make
Seen the following error:
i386-pc-msdosdjgpp-gcc -g -O2 -o gnuchess.exe atak.o book.o cmd.o epd.o

Apply trick on:
https://github.com/maxmind/libmaxminddb/issues/144#issuecomment-757101861
that is:
ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes ./configure
--with-gnu-ld --host=i386-pc-msdosdjgpp
where --with-gnu-ld was ignored I think
make
and there in src is:
paul@kasparno:~/Téléchargements/chess$ ls -lh src/gnuchess.exe
-rwxrwxr-x 1 paul paul 2,0M jun 23 01:20 src/gnuchess.exe
So I transfer this simple file in DOSEMU2, played about 3 or 4 moves.
Works well... no escape codes.
Well, I remove my Linux gcc because at first I had forgot about using
./configure --host=i386-pc-msdosdjgpp
If someone want to test... and or make a release file... I could rename it's
extension to .xex and send it to you by email I think.
Does not react to ^C, but accept exit or quit command.
Or help command... that show among command show.
help show, indicate it is possible to show board
