+Subject: [PATCH] include standard header <cstdint>
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+gcc 13 moved some includes around and as a result <cstdint> is no longer
+transitively included [1]. Explicitly include it for uint64_t.
+
+Fixes errors like below
+
+In file included from ../rdfind-1.4.1/Fileinfo.cc:22:
