They are problematic in mkgmap too, they have simply not been noticed
there before.

Because the new file in splitted showed up in my license & copyright
review for the changes since SVN r548 (the previous revision in Debian).

Ideally all the files in mkgmap and splitter are relicensed to GPL-2+
(v2 or later) to have the most widest license compatibility. Only the
copyright holders can change the license, so this is something you,
Steve and the other copyright holders need to consent to.

Kind Regards,
