As far as I see in RFC 3174, the C++ code is not there but I agree that 
code is near identical. The C++ code has a copyright and "All Rights 
Reserved" and no license. 

A separate license.txt file give distribution permission but no 
modification and redistribution of modified version permission.

I am not sure we can use the RFC 5378 rights for the C++ code. 
Especially since it conflicts with the newer C++ code copyright.

Regardless of what it used, it needs to be documented as in comments 
in the code, as others may use it and need to know their rights. (They 
can't assume it is ISC licensed code.)
