I just check if Wireshark can be build using Qt5.10 and std=c++03, but
this cannot be done - there is a need to have the compiler with C++11
(with correct flags). So if one day we drop support for Qt < 5.7, then
we will "must have" C++11. Qt 5.6 LTS ends on 16.03.2019 (quite
soon). Qt 5.9 LTS ends on 31.05.2020.
But this is about Qt5 requirements in future, but we can still use
C++11 from now. This will solve also my issue about "I have Qt 5.10
and nobody warns me about using C++11 features, except Ubuntu-based
Petri-Dish {unexpected surprise}".

I know we've had the C vs C++ discussion before and I'd still vote for keeping things where they are as far as "GUI" is C++ and epan + dissectors (i.e. libwireshark) as C. I'm a little more indifferent to the "peripherals"/tools. Other than some "shorthand" in syntax, I don't see the necessity to "upgrade". Are we missing out on some Qt features because of no C++ 11 support?
