     I'm trying to get gnuchessc
from the gnuchess-4.0.pl63.tar.gz distribution to work with
/usr/games/chesstool running on a SUN sparc system, SUN 4.1.3.

     gnuchess was compiled with gcc-2.5.7.

     gnuchessc is generating output that is not compatible with chesstool,
as the following output shows.  As a result, chesstool does not work
with gnuchessc.

$ gnuchessc
Chess
e2e4
1. ... e2e41. ... c7c6
My move is: c7c6
quit
$ exit

Listed below are some of the my patches to attempt to fix the problems.
However, without really studying the code in detail, there isn't
much more I can do with limited time.

The patches below attempt to fix the following:
     1. chesstool does not expect bell characters.
     2. the "My move is . . ." should not be printed.
     3. Each half move should be on separate output lines.
     4. A printz (CP[15]) prints a wrong message.
     5. gnuchessc should terminate on SIGINT.

The following problems remain:
     1. A control-D, EOF character as input should terminate gnuchessc.
     2. The response for castle
        as o-o or o-o-o is not compatible with chesstool.

Any official patches appreciated.


Thanks,
Andrew Sun
