Dear FTP Masters,
I've been asked by Julien Cristau (who reads this message in copy) to
get a confirmation in an "authoritative statement from ftpmaster" that
the CeCILL-C license is GPL-incompatible.

As you can read above, I asked him to clarify what he is disagreeing
about, but I haven't received any reply.

Please read the full #741196 bug log, if you need more context.

If you agree with me that CeCILL-C is GPL-incompatible, then I think
that the severity of bug #741196 should be raised again to "serious"
and its "moreinfo" tag should be removed.

Could you please express your opinion?

Thanks for your time!
Bye.
