+Subject: [PATCH] t/generated-code2/cxx-generate-packed-data.cc: Fix build
+ failure on newer protobuf
+
+ Upstream-Status: Backport [https://github.com/protobuf-c/protobuf-c/pull/369]
+
+google::protobuf::Message::Reflection has been removed in newer versions
+of protobuf. The replacement is google::protobuf::Reflection.
+
+protobuf in commit 779f61c6a3ce02a119e28e802f229e61b69b9046 ("Integrate
+recent changes from google3.", from August 2008) changed the following

+    +  // Typedef for backwards-compatibility.
+    +  typedef google::protobuf::Reflection Reflection;
+
+The "typedef for backwards-compatibility" apparently lasted ten years
+until protobuf commit 6bbe197e9c1b6fc38cbdc45e3bf83fa7ced792a3
+("Down-integrate from google3.", from August 2018) which finally removed

+
+This commit updates the only use of this typedef (in the test suite) to
+directly refer to the replacement, google::protobuf::Reflection. This
+fixes the build failure in the test suite.

+Subject: [PATCH] Added stubs/map_util.h to list of installed headers
+
+This should fix issue #6186. I also had to remove a couple unnecessary
+const keywords in map_util.h because the no_warning_test was showing
+errors about those.
