The authors have tweaked the license again, here is the new version:

1.1 Software License

   Permission is granted for all uses, commercial and non-commercial, of
   the sample code found in Section 8.  Royalty free license to use,
   copy, modify and distribute the software found in Section 8 is
   granted, provided that this document is identified in all material
   mentioning or referencing this software, and provided that
   redistributed derivative works do not contain misleading author or
   version information.

   The authors make no representations concerning either the
   merchantability of this software or the suitability of this software
   for any particular purpose. It is provided "as is" without express or
   implied warranty of any kind.

Do you see any loopholes in this that make it non-DFSG-free?

Thanks,
