The LaTeX project public license has similar terms
<http://www.latex-project.org/lppl/lppl-1-3c.html>, the FSF considers
version 1.2 and 1.3a of that license "free but GPL-incompatible"
<http://www.fsf.org/licensing/licenses/index_html>, so I'd guess it falls
in the same category. OSI is silent on this.
