Subject: Question to 64 bit experts

Hi,

I am porting my chess program to 64 bit on an AMD64 Athlon processor. I have
noticed that, with gcc, sizeof(int)=4. I would have expected sizeof(int)=8. On
32-bit platforms, 32-bit variables are faster than 16-bit variables. I wonder if
64-bit variables are faster than 32-bit variables on 64-bit machines. I have
made a few experiments and did not notice much difference.
