It is perfectly possible to run gnuchess on an 8Mb system.  I would 
suggest that you don't edit the source (though the defaults are the 
definitions are ttblsz or something like that in src/ttable.h and 
DEFETABS in src/gnuchess.h), but rather use the -C and -T command-line 
options (which even work for gnuan, though not documented in the manpage).

The defaults are `-C 18001 -T 150001' (for msdos, -T 8001).  On my Linux 
system, this uses just over 9Mb.  From memory, `-C 6001 -T 40001' uses 
around 3Mb.  Fiddle with these and see what results you get.

I will at some point get round to updating the Linux version of gnuchess, 
since I'm maintaining the Debian GNU/Linux version; however, it will be 
AT LEAST a month before I get time to even think about this ...

Hope this helps,

Nikhil.
