Bug#843078: pokerth: FTBFS: qobjectdefs_impl.h:72:88: error: '>>' should be '> >' within a nested template argument list

Control: retitle -1 pokerth: -std=gnu++98 workaround no longer works with Qt 5.7

Thanks for your report.

The core of the problem is:

g++ -c -m64 -pipe -std=gnu++98 ...
...
/usr/include/x86_64-linux-gnu/qt5/QtCore/qcompilerdetection.h:562:6: 
error: #error Qt requires a C++11 compiler and yours does not seem to be that.
 #    error Qt requires a C++11 compiler and yours does not seem to be that.
      ^~~~~

This package uses -std=gnu++98 as workaround for code that is not 
valid C++11 code, but the headers of Qt 5.7 (that just entered unstable) 
require a compiler in C++11 (or higher) mode.
