[ITK] [ITK-dev] Linux c++11 build issue v4.8.2

With 4.8.2 - I built ITK with C++11 (this required -fpermissive to complete)
Despite doing that, I was still unable to built ITK applications with 
C++11 (even when also using -fpermissive).

Let me know if you've had different results. I was hoping this would be 
resolved with 4.9.
