If it's just unnecessary but not > harmful, I'd probably ignore the patch. $ grep -rE '(^|\W)const(\s+\w+)+\s+const\s' I just happened to notice some unnecessary const in our internal code, so I grep'ed for it in a couple big OSS projects to see how common it was. Since I found only a few, I decided to remove them, but like I said it just gets ignored by all the compilers I know, so there's absolutely no harm in leaving this dead code around. > That's fine.

So, do you want me to split them up? I'd prefer not having to (slightly less work for me :P), but it doesn't really make much of a difference either way. Cheers
