+Subject: [PATCH] Fix autoreconf with gettext 0.25
+
+Since gettext 0.25, the AM_ICONV macro is installed into the m4
+directory, so we need to add that autoconf config directory.  We also
+need to make sure autoreconf recognizes that it needs to run autopoint
+to install the gettext macros, which it does heuristically by checking
+whether AM_GNU_GETTEXT_VERSION is used, so add that and the minimum
+amount of other stuff required to make it happy.  The version of
+gettext we say we use shouldn't matter, so I just went with the
+version in ubuntu:latest since that's what CI uses.
