Then state so clearly. We have LGPL header examples in the
code already, additionally stating that the LGPL vs GPL
aspect does not apply to all of Samba. Somewhere we also
used to have a statement about our IDL files, stating
essentially their public domain status.

I just want to make sure that we are crystal clear and very
obvious about the licensing status of our code. If someone
has to take a second look to find out what licensing status
a file has, this is very, very bad from my perspective. For
third-party code we also must make very sure the source is
authoritative to publish the stuff under the license we are
importing it under. I've had regular queries from lawyers
about exactly these questions in the past, and you are not
in a good situation if you can't answer them or even have to
think twice.

Regarding the value of a long GPL header on a small file: Is
your disk space really that limited?
