I'd like to propose raising the minimum version for GCC to 4.8.1, which is the 
first C++11 complete version, or higher. The reason for this is actually to 
drop GCC 4.7 and earlier, which have a few bugs with their C++11 support. GCC 
4.7 has been the minimum since Qt 5.7.0 and is now 5 years old.

I've just been bitten by one with QRandomGenerator, relating to calling static 
member functions from a lambda. The workaround suggested in the Coding 
Convention is not applicable going forward because Clang 5.0 will produce a 
warning about it (I've updated the wiki), so we have to choose which one we'll 
support very shortly, as soon as Apple begins shipping Clang based on the 
current trunk version in XCode.
