I can only say, Red Hat Enterprise is still in use, a lot, and still supported until 2017 with even longer support
extensions possible (I would appreciate if people would upgrade to 6 or 7, but yeah, I can't force them).

Given you even get modern toolsets for it, with gcc 4.8.x, it was no real problem to
compile most parts of Qt until 5.5, you only need to ship some more up-to-date libraries with your product.

That now even QtCore is not compiling is IMHO not that nice.

I would stick with Qt 5.4 a year longer, but given it has some interesting issues, that are only
fixed in 5.5 for real, that is no real option, too.

But don't get me wrong: I don't want to try to force somebody to now fix that, I just
wanted to state that there ARE users of Qt that use it on such old machines and that
they now will have a problem, like me ;=)

Greetings
Christoph
