This doesn't sound like a problem. In a jurisdiction where public domain is legal, type the code in by hand. Public domain means anyone is free to copy it. Once you type it in, you own the copyright (it's your work), and you can license it under MIT, BSD, whatever.

Or is there a specific jurisdiction that claims that DJB's original copyright somehow overrides that?
