Xcode 5 Analyze warnings about ziparchive

[mattconnolly]

Are these warnings in the mini zip sources? I'm less inclined to change those because that is code from another library that ZipArchive wraps to objective C.

Happy to discuss though.

It is in the mini zip code. Some are just about declaring prototypes and others about setting variables which are then not read. I was thinking of using directives to at least suppress these warnings so that anyone using this code would not start seeing these warnings. I looked for directives to suppress these warnings but did not find them with my cursor search. Since this is code we know works I am OK with suppressing these warnings. For the prototypes it is fairly simple to just pre-declare the functions to eliminate those warnings.
