Talking about birds, here is the result of Gaviota (Seagull).
pIII 800 mhz, 0.4 seconds.
It looks like it has the right kind of extesion for this particular
position. So, I think it will be easy for most of the programs.
I am happy that Gaviota is returning the right number (Mate in N) for all the
tests I was trying today. It looks like it is working quite well now
after I fix that.
