There's a patch in -staging and -next for that, it may need adoption for 3.1 but would be needed to fix all build failures. I do not have good internet currently and am busy, so I can't do anything to fix those problems, but I should have time and connection to review patches for 3.1 (perhaps adapted from the -staging one). > > Am Samstag, 8.
