add proper copyrights

was a mistake on my part and a leftover from the first iterations.
Initially I only stole a few bits, that's why the comment but not the
copyright, but then i threwed out and restarted using oconfigure.
Then the configure script has its own independent changes, but need to
give attribution nevertheless.
