I tried several versions now (4.1, 4.3. 4.4pre) and all showed the
error. I'm using ccache, maybe this has something to do with it? (Though

I have another config that builds properly. Actually I just changed some

try to filter out the guilty option if there is any. But I possibly
won't find the time before mid of the week.
