And I am willing to looking at FLAC and spent my time to fix compiler 
warnings to make it more portable and fixing potential issue and you 
are being such a dick to me. As mentioned in my first mail I have 
some patches lined up.
Very smart move to turn off a external contributor.

Also I mentioned in my first mail, that I have no idea what the 
intention of that code is, so maybe just telling that instead of 
telling me might have given me the change to fix it myself and then 
submit that.

Wow...that's a lot. We had to disable just one warning for now. I got 
the feeling that list might have some obsolete ones in it.

I am aware of that and it appears you have no clue what autotool 
actually does, since the file won't be "the exact same header fiile" 
since autotool generates a completely different one for each system 
you use...

The question is what version you are using officially since I haven't 
seen that warning before myself and I updated FLAC before and didn't 
get around to commit it in our project and I didn't see it then. I 
assume it's new to GCC 4.9.x and clang 3.5. LTS or not latest version 
don't carry that yet and I guess you will run into that yourself as 
soon as you update.
