Description
I'm attempting to build Qt 5.6.2 LTS on CentOS 6 with the Intel Compiler (17.0.2) with the following configuration:
/home/developer/Downloads/qt-everywhere-enterprise-src-5.6.2/qtbase/configure -prefix /opt/qt-5.6.2 -skip qt3d -platform linux-icc -qt-xcb -c++11 -confirm-license "$@"
While qmake is created, the build fails immediately with errors similar to the following:
qtbase/include/QtCore/../../src/corelib/global/qflags.h(144): error: class "std::initializer_list<Qt::AlignmentFlag>" has no member "const_iterator"
I've attached the configuration and build log with the issue so that you can see all the details.
I've also tried building Qt with gcc (which works fine), except that I can't build any applications against that version of Qt with the Intel compiler. Not sure if this should be a separate issue, but it generates errors similar to the following:

I have a feeling this might be related to how Qt detects supported compiler features, but I'm not sure.
