+Subject: [PATCH] configure.ac: call AM_INIT_AUTOMAKE only once
+
+That second call seems to be there since the beginning, and autoconf
+2.69 was fine with it. autoconf 2.71 doesn't allow it anymore:
+
+    $ ./autogen.sh
+    autoreconf: export WARNINGS=
+    autoreconf: Entering directory '.'
+    autoreconf: configure.ac: not using Gettext
+    autoreconf: running: aclocal --force

+    configure.ac:19: the top level
