None of the CeCILL licenses are suitable for code in scipy, in my
opinion. The CeCILL-B is closest, but it has attribution requirements
that are stronger in some ways than the GPL-incompatible advertising
clause in the original BSD license. I'm pretty sure it is not
GPL-compatible, and I doubt it will be considered DFSG-free or OSI

The CeCILL license (~GPL) and the CeCILL-C license (~LGPL) are not
suitable for obvious reasons.

While it is worthwhile for the author of the patch to ask Konrad, I'm
pretty sure that code existed in ScientificPython before Konrad
switched from the BSD license to the CeCILL license and could be
forked from a previous version of ScientificPython.
