+Subject: [PATCH] resize: Depend explicitly on Unix module.
+
+Commit a0722c7ad846960be54978a31ebe73b76e119203 introduced a
+dependency on the Unix module.  This was not listed in the list of
+'-package's, but as long as you had ocaml-gettext installed it would
+still work because that pulled in Unix implicitly.
+
+Thanks Olaf Hering.
