Re: Fun with Squid2 and Clang

Maybe that it's C++ while the others are C?

Hmm.. from Clang homepage

        "The Clang Static Analyzer consists of both a source code
        analysis framework and a standalone tool that finds bugs in C
        and Objective-C programs.".

C++ is not C or Objective-C, so it's not too strange it doesn't work for
C++ programs.

And some seconds further digging gives

    http://clang.llvm.org/cxx_status.html
