(svn r8605) -Codechange: [OSX] changed all objective C to objective C++
This will permanently solve the issue where compilation on OSX broke because C++ code was added to some header files

-Note: (important if you develop mac specific code)
taken from http://developer.apple.com/releasenotes/Cocoa/Objective-C++.html
gdb lacks an integrated C++ with Objective-C parser. This means that gdb won't be able to evaluate expressions that contain both C++ and Objective-C constructs.
gdb assumes that the language for ".mm" files is C++.
you can change it to objective C by typing: (gdb) set language objc
Mixing C++ and objective C has some limitation (see link for all of them)
