The gnuchess.exe and gnuchesr.exe included here are compiled from
unmodified GNU Chess 4.0.77 sources, available on the Internet as
http://www.tim-mann.org//gnuchess/gnuchess-4.0.pl77.tar.gz. To recompile,
get the source and unpack it using GNU gzip and GNU tar, then recompile
with Microsoft Visual C++ by typing the command "nmake /f Makefile.nt"
to an MSDOS Prompt box on Windows 95 or Windows NT.  If you have a
different compiler, you are on your own; sorry.  Afterwards, rename
gnuchesx.exe to gnuchess.exe.

The gnuches5.exe included here is compiled from the GNU Chess 5.02
sources, available as ftp://ftp.gnu.org/gnu/chess/chess-5.02.tar.gz,
with slight modifications; see the file gnu502+.patches.txt.  To
recompile, get the free Cygwin tools from www.cygwin.org and use them
to unpack the source (gzip and tar), patch it if desired, and compile.
