+Subject: [PATCH] Don't copy Makefile.dist to Makefile in distclean
+
+Note that make doesn't wait for this background task to finish. During
+rpm build we are building mtr twice. After first build we call
+distclean. If second invocation of configure script runs in less than 3
+seconds then the Makefile generated by configure will be overwritten by
+background copy. We don't want that and since we are calling configure
+explicitly we don't really need this "feature" at all.
