Funny. It seems we worked on this bug at the same time. I can confirm
that [2] resolved the FTBFS with GCC 7. However it was not clear to me
how [3] could fix [4]. I suggest to add a simple patch to bug reports
next time which tremendously simplifies things for non-regular uploaders
of Widelands.

Anyway I believe this bug should be fixed in a couple of minutes. Thank
you for your assistance.

Regards,

Markus
