Hi. Sorry I don't have any info about C++11 code in 5.6 branch. I'd like to comment for Simon's question about devltoolset requirement.
According to this thread [1] maybe the binary distribution of Qt 5 requires newer(4.7?) libstdc++ than the one which is provided by RHEL/CentOS 6.(4.4.7) This might lead updating wiki article of building qt5 to add this workaround. The Red Hat Developer Toolset has been released 4 times for RHEL5/6 release (1.0 to 3.0) and currently only 3.0 is supported on RHEL6. [2] I think These are reason why for this requirement. And I don't know if the older version of Qt5(5.0,5.1..) could be built with gcc 4.4... By the way, RHEL6 is now at second half of its 10 years support life cycle. [3] I think it would be better to start to consider about Qt5 support for RHEL7. As RHEL7 has gcc 4.8, the devtoolset is not needed.
