dns_cache is solved at b3c8f92fe48ac90802c989c74c3a34cfea065861
The rest are not solved on master.

For sure that you know. You made the patches :-) This is what I found for clean the warnings on the 4.0 branch. All cherry-picks from your commits to master. It will be nice to push the changes to 4.0 branch
Hello Victor, thanks for collecting them -- typically the developer should pick them in stable branches, I usually try to spot what's not done by release time, but I missed these one. I'll get them now and compile on wheezy (just set up a vm for it) to check the others. Cheers, Daniel On 5/7/13 3:53 PM, Victor Seva wrote:
