Hey Rainer,
Ops, sorry, I kind of forgot about this. We've had face-to-face
meetings, and then I left on vacation. It is enabled now.

Ah, that's because of BuildBot's algorithm to detect warnings. I
honestly never go to the "warnings" page because of that; I prefer
looking directly at the logs. I don't know if BuildBot has improved its
warning detection in newer releases.

guess they've been ignored for a long time, now.
