+Subject: [PATCH] add support of protobuf 4.22.x
+
+After upgrading the protobuf to 4.22.x, the protobuf-c cannot compile anymore due to following changes:
+1. protobuf using c++14, that cause the command_line_interface.h report error
+2. protobuf using abseil-cpp library instead the trace API with GOOGLE_ header
+3. removed GOOGLE_DISALLOW_EVIL_CONSTRUCTORS
+
+Upstream-Status: Pending [https://github.com/protobuf-c/protobuf-c/pull/548]
