Please see:

| 48. How much do I have to change in my own work to make a new claim
|     of copyright? 
|     You may make a new claim in your work if the changes are substantial
|     and creative -- something more than just editorial changes or minor
|     changes.  This would qualify as a new derivative work.  For instance,
|     simply making spelling corrections throughout a work does not warrant
|     a new registration -- adding an additional chapter would. See Circular
|     14 for further information.
| 49. How much do I have to change in order to claim copyright in someone
|     else's work? 
|     Only the owner of copyright in a work has the right to prepare, or
|     to authorize someone else to create a new version of that work.
|     Accordingly, you cannot claim copyright to another's work, no matter
|     how much you change it, unless you have the owner's consent. See
|     Circular 14.

Circular 14 is a publication of the United States Copyright Office, and
covers "Copyright Registration for Derivative Works".  It is a 4 page
PDF document, which can be obtained from:

One of the things it clearly states is:

|     The copyright in a derivative work covers only the additions,
| changes, or other new material appearing for the first time in the
| work.  It does not extend to any preexisting material and does not
| imply a copyright in that material.
|     One cannot extend the length of protection for a copyrighted
| work by creating a derivative work.  A work that has fallen into
| the public domain, that is, which is no longer protected by
| copyright, may be used for a derivative work, but the copyright in
| the derivative work will not restore the copyright of the public
| domain material.  Neither will it prevent anyone else from using
| the same public domain work for another derivative work.
|     In any case where a protected work is used unlawfully, that
| is, without the permission of the owner of the copyright,
| copyright will not be extended to the illegally used part.

Aside:	Note the semantic value of the words "using" and "used" in
	the above; they are clearly in conflict with the word "use"
	and its derivatives as it appears in the text of the GPL.

Note that both Linux and FreeBSD are probably in legal violation
of Section 407 of title 17 of US code at this point, unless there
has been a specific effort on the part of the projects to comply
with the mandatory deposit regulation within 3 month of each
publication.  See:
