I think I only tried out with the new configs but not all the rest configs. I thought there're some bot looking after that one, from which I used to receive build reports. And IIRC I fixed some build issues in early versions from those reports. Maybe I was wrong.. Any more hints on the latter? Thanks, -- Peter Xu
