Now I understand: My changeroot is sid, but the host machine runs on
testing, so I didn't get the latest compiler version. The culprit now
is that with g+++ 7.2.0 one can give -Werror=format-security without
setting also -Wformat, as of g++ 7.2.1 this is now an error, and one
needs both, -Wformat and -Werror=format-security, hence the error.
