    Description

      qendian.h uses std::numeric_limits but does not #include <limits>. As a result, any QT application using QtEndian fails to build with gcc11 (e.g. Fedora Rawhide) with a ton of errors like:

      In file included from /usr/include/qt5/QtCore/qendian.h:44,
from /usr/include/qt5/QtCore/QtEndian:1,
from yet_another_qt_bug.cpp:2:
/usr/include/qt5/QtCore/qfloat16.h:300:7: error: 'numeric_limits' is not a class template
300 | class numeric_limits<QT_PREPEND_NAMESPACE(qfloat16)> : public numeric_limits<float>
