To C++11 or not?

Hi,

:=) Actually I wonder why somebody should do that given you get even from Red Hat (or CentOs)
GCC 4.8 or now even 4.9 for the 6.x series that will allow you to deploy on any system
that is really out there and able to run Qt 5 (For CentOS 5 you get similar new GCCs,
but that has other issues)

(and we do that for our customers since ever)

Greetings
