+Subject: fix: retain compatibility with MSVC++
+
+The C++ standard has always forbidden containers of const elements such
+as std::set<const T>.  In order to retain compability with MSVC++ this
+code can not exist in Chromium.
+
+This should probably also be fixed in libc++ to prevent this occurring
+again but this fixes the build for now.
