Aye, it's pretty frustrating for me trying to report anything. Any time
a bunch of headers change produces a bunch of file rebuilds and
therefore warnings. That should in theory be caught by the fact that we
apply the patch & build, jump back to HEAD~1, build that & grab the
"before" warning state and then jump forward, rebuild the patch and
gather the "after" state. The idea is that that is an apples:apples
comparison as the same files will need to be rebuilt for both but it is
falling over somewhere. Maybe I'll have time to look into that soonTM.

Ye, that's my bad I think. In a rush off to another patch before the
thought I had on it left my brain and just pressed reply on the wrong
email. Sorry bout that :)
