Comments regarding including updated NetBSD into libcdio

["R. Bernstein" <rocky%panix.com@localhost>]

Karl Berry has been going over the libcdio code
(http://www.gnu.org/software/libcdio) to change it from GPL V2 to
V3. In the process he remarked

  The BSD license used these days (no advertising clause) is compatible
  with the GPL (both 2 and 3).  So you can incorporate BSD-licensed code
  in libcdio, there is no legal problem.

The particular file in question is 
http://cvsweb.netbsd.se/cgi-bin/bsdweb.cgi/pkgsrc/misc/libcdio/files/_cdio_netbsd.c?rev=1.3;content-type=text%2Fx-cvsweb-markup
  

which he maintains is compatible with GPL and mentions
http://www.gnu.org/licenses/license-list.html . Basically, he says one
keeps the license of the original code.

So if he's correct and there is no *legal* problem, there is of course
there's the question of whether folks would take offence and/or if it
would be desireable. I've sent email to drochner at the netbsd org
address asking for his view since his email is listed on the existing
0.76 source code.
