[Development] Fwd: Change in qt/qtbase[5.6]: Make the C++11 atomic support the default, if available

[Thiago Macieira]

FYI

Please report any issues you have with broken compilers that did not implement 
std::atomic properly. I'd like to include them in the release notes.

These are already known to fail, so please don't report them:
- Xcode 5.0's clang compiler says it supports constexpr but doesn't
- ICC on OS X has a broken <atomic> header that misses some casts

Those compilers are now blacklisted in C++11 mode. For Qt 5.6, you can pass 
the configure option -std=c++98 or -no-c++11 and you'll be able to use them. 
They will not be supported in Qt 5.7, so please schedule your upgrade before 
the 5.7 release.

----------  Forwarded Message  ----------

Qt CI Bot has approved a build with this change and it was merged.
