I emailed the author about it, and the author said to me...

"All of the code is PD unless otherwise stated. I believe each tutorial 
mentions this at the start, and including it in the code snippets would 
be redundant and waste space."

His email is ' happyfrosty at hotmail.com ' if you want to double check. 
  I told him that the words public domain never appear on the red black 
tree page and that he should add it.
