Hi.

I've been learning assembly the last few days because I needed to 
understand a segfault in my OCaml binding of the MonetDB database 
system. Problem now solved: symbol collision with libncurses. Thank you, 
since this book has helped me gain a lot of time and avoid hours of 
frustration.

As I've been working on amd64, I took some time to adapt the examples of 
the book to amd64. Here are the first three.

If people want to contribute examples of Programming Ground Up to amd64, 
feel free to tell me to 'git pull'.

Thanks again.
