 As far as I understand it, this patch will make root use --enable-c++11
 and libc++ if either: clang is the system compiler or one of the clang
 variants was chosen for the port.  Is that right?  I'm still on OSX 10.7.5
 (not planning to upgrade anytime) and wish to use C++11 library and
 language features in ROOT, I'm flexible about which runtime and which
 compiler I use to accomplish this.
