Thanks for all answers. Very short time ago I got Crafty and we 'll
try it. I
posted that question also by the reason that I couldn't persuade my
father
that gnu 5.02 is not an "intentionaly weakened version of gnu 4.0". I
'll try the newest versions of 5.xx ,too. By the way, why was it
necessary to abandon gnu4 and to start gnu5 from ground zero?
Thanks again:-)
