Error including opencv headers after upgrading to g++-11 #20269
Description
System information (version)
- OpenCV => 4.5.1+dfsg-4
- OS => Debian Sid/Experimental
- Compiler => g++-11 (Debian 11.1.0-3) 11.1.0
Detailed description
When I upgraded my compiler to g++-11, just to see if some bug in gcc was already fixed, I found out a new one. It started reporting an error from a system header, which may be even another bug in g++-11, but still, you might want to fix it in OpenCV anyway, so I'll report it here.

Steps to reproduce
I compile with -Wall -Wextra -Werror. Including that header, using those warnings/errors, and the latest g++ should be enough to trigger the error.
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues,
forum.opencv.org, Stack Overflow, etc and have not found solution
BTW, I found this similar report: https://stackoverflow.com/questions/63601869/error-in-compiling-opencv-program-with-g-and-clang - I updated to latest OpenCV version and the issue is still there
- There is reproducer code and related data files: videos, images, onnx, etc
