For small files I'm fine with just referring to the COPYING
file that should be shipped with the distribution.

There's still remnants of the older stuff.  Probably the
easiest is for the old authors to sign copyright over to the
new author.  IANAL, so I don't know the answer to the
question "if a file is replaced a little at a time so that
it is all new code, is it still a derivative work of the
original."  The old BSD / ATT lawsuit would suggest that the
answer is no, but we should ask a real lawyer.
