As Kong Sian has noted the new genmoves is considerably slower than the old, and
it may represent a bad solution to the problem but there is a real problem.

genmoves is used for 2 things in gnuchess. It is used to generate moves and it
is also used to verify oponents moves. The old genmoves worked fine for generating
moves but it generates illegal moves. So when it is being used to verify moves
it will allow illegal moves. When gnuchess demanded that input moves be in
full algebraic format (i.e. e2e4) that wasn`t a problem because they could
never be ambiguous. But allowing moves like Nd2, often both knights could have made the
move and it wasn't clear which move was correct. But one of the knights was pinned
so it could only have been the second to move. This showed up when the ICS move 
format was changed to shortened algebraic. So the new genmove. 

Perhaps teh correct solution is 2 genmoves. 1 for generating and 1 for verification.
