Even if it's only been used in a 0x0 "compliant" way?

Note that the Qt 5.7 policy still allows and even asks for use of 0 as null in
some places. The policy is:

Heh, I had the same approach. :)

Already done, since 2007. but it's in the "extra" checkers, ie. not enabled by

In that case, I retract my previous comments. Where are the *proper*
requirements documented then (for future reference)?

It lists both CI tested and untested things there.

We could just detect the compiler, and in need define nullptr 0x0, look the
other side and hope for the best (ie. anybody on modern compilers anyway and
nobody actually making use of std::nullptr_t atm. but just of the keyword) -
not very nice, but better than breaking compilation(?) and not as

This is from the "Officially supported platforms" page at
http://doc.qt.io/QtSupportedPlatforms/
Qt 5.5:
Windows * - MinGW 4.9, MinGW 4.8 (apart from MSVC)
Linux - 32/64bitgcc 4.8.1, gcc 4.9.1
I thought that was official enough.

s/8/5/ and you'd be correct.
The Qt minimum version will rise to GCC 4.7 with Qt 5.7 and Qt will stop
compiling in C++98 mode at that ti

Yes, we did set up the rule requirements for gcc 4.5 and MSVC10 back in 2013.
Since then, we broke the rule and increased to MSVC11 (VS2012).
Now, we can in

I don't really see why it is "against the nature of KF5". It would not
be the first time we require a higher compiler

For applications, it's 100% up to the application developer. I'm sure

However, since some time now, kf5 libraries are full of nullptr (~400
