Hi all,

[https://bugreports.qt.io/browse/QTBUG-108228 for details]

After looking at libc++, libstdc++ and MS STL's <version>, it seemed 
like it wouldn't #error out if #included in a C++17 project. So I've 
kicked off a precheck on Gerrit, and so far, it looks like Integrity is 
the only tool-chain that doesn't have a <version> header, yet:


On other tool-chains, it appears to be usable in C++17 builds, too. 

I'll ask our Integrity experts to find out whether there are any plans 
by GHS to add this header before their next major release, or as a 
patch that Qt users could apply to their installation.
