    cmake: Objective-C compilation support with clang and C++11

    This fixes an issue when compiling with C++11 flags on: the
    objective-C clang compiler produces an error. This patch set
    the -std option to ansi for the Objective-C sources.

This change is not good with clang 4.0 here:

For Objective-C sources I have many "C++ style comments are not allowed" 
warnings now.

Please find another solution, e.g. (...COMPILE_FLAGS "-std=c99") if this makes 
sense.

Yes, that makes sense.
