+Subject: [PATCH 1/3] Fix libcxx build without <tr1/*> (use <memory> if
+ available)
+
+With Clang & libcxx 15, tr1/* doesn't seem to be available,
+which is fine, as we can use the proper <memory> header
+instead.
+
+We already do this in several other locations. Fall back
+to tr1 and Boost as before.
