Is this the case? http://git.savannah.gnu.org/cgit/gnulib.git/tree/doc/Copyright/conditions.text says the following:

    * Public domain.

    If you put the program in the public domain, we prefer to have a signed
    piece of paper--a disclaimer of rights--from you confirming this.  If the
    program is not very important, we can do without one; the worst that could
    happen is that we might some day be forced to stop using it.

Clément.
