(svn r8141) -Fix r8128: [OSX] now OSX can compile again.

Note: this is again another not so nice workaround as Objective C fails to include C++ code in the headers
    We should move to Objective C++ as soon as possible, but such a change is not done overnight and
    this quick fix will allow OSX to compile until the prober solution is done
