From bf4695266bfca8cc21bcf10a3281e874ebce0d27 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Fri, 3 May 2024 02:44:11 +0300 Subject: meson: Deprecate bitwise operations between different enumeration type C++20 deprecates bitwise operations between different enumeration types. This is a bad practice even in C++17, so enable the deprecation warning. Doing so ensures no such operations will be added.
