I've tried compiling gnuchess4.0.pl60 with gcc 2.3.3, and I consistantly  
get an infinite loop (usually after 4-5 seconds of successful operation).   
It happens around line 54 of atak.c in the loop

          do
            {
              a[u] = ((a[u]+1) | c);
              u = ((color[u] == neutral) ? ppos[u] : pdir[u]);
          } while (u != sq);

Obviously u never gets to equal sq here.  Anyone else have such a problem,  
or is this old news?
