I'll make a try to get in contact with K&R. About the book with the solutions. Is it published under GFDL or any other free documentation license? Cause if this is the case, I prefer to do something that will be more useful to the free software community.
Thank you for the tips. I will inform you when I'll get a response from the authors (at least hope to get one!). Regards, Athanasios.
