qt5 error: 'numeric_limits' is not a class template with gcc-11

[rhermsen]

Using qmake I get errors

Code: [Select]

/usr/local/include/qt5/QtCore/qfloat16.h:294:7: error: 'numeric_limits' is not a class template
Searching for these errors point to GCC-11 changes requiring #include <limits>

From the following I get that
https://bugs.gentoo.org/768342
https://bugs.gentoo.org/768354
https://bugs.gentoo.org/752012
QT-5 requires recompile with the patches.

The majority of the patches look to be in the following attachment:
https://752012.bugs.gentoo.org/attachment.cgi?id=681397



Can someone help with that?
