Same with code that cannot be BSD either by infection from a part, or
because it is a translation of non-BSD code from another language.
Also, some code on the matlab fileexchange  that is labeled BSD might
not be so because it is based on (derived from, translated from, or
inspired by) non-BSD compatible code.

There are also license mixtures like
http://ab-initio.mit.edu/wiki/index.php/NLopt which is only LGPL
because a small part is LGPL:
"Free/open-source software under the GNU LGPL (and looser licenses for
some portions of NLopt)",
