This was already mentioned in the thread
"[Announce] Changes to building Qt on Mac OS X"

Can we not still target OS X 10.6 while using libc++?  
(provided of course that libc++ is also shipped with that application in 
addition to Qt for that platform)

That way we can still support os x 10.6 while stopping supporting obsolete 
gcc.

(Then we could start using C++11 features in Qt, such as auto or lambda, which 
I think are worth it)
