I have alpha, sparc64, and a few more so we can get pretty good coverage before it hits -next. If we enable more build coverage then please address all W=1 warnings first. I for once always builds with W=1 these days, and I see more and more warnings sneaking in again. So lets try to keep the noise level down. Sam
