 Just add your user name to CC

 > The HDCD utility provided was apparently written by Chris Moeller
 (author of Foobar), Nick Gorham and Jim Lesurf. The license statement from
 the tarball is attached.

 You attached the license of the original code that the code you used was
 based on. The original license allows everybody to "use" the code in any
 way, including to write a proprietary (non-free) application. The new code
 (the one you used) contains no license statement, it is therefore not free
 software (at least where I live, public domain does not exist, and I did
 not find any hint that the author wanted his code to be free software).
 The only restriction in the original license is that if the source code is
 distributed, the original copyright notices must not be removed, It seems
 to me that the author violated this restriction or do I miss something?
