+Subject: [PATCH] qfloat16: Include <limits> header
+
+gcc11 complains
+ error: 'numeric_limits' is not a class template
+ |   344 | template<> class numeric_limits<const QT_PREPEND_NAMESPACE(qfloat16)>
+
+This is because its missing right header which perhaps is included
+implicitly in older compilers
