+Subject: [PATCH] libparted/labels: link with libiconv if needed
+
+gpt.c uses iconv so it should link with it. Otherwise, on platforms
+where libiconv is a separate library, we get a link failure of parted:
+
+    CCLD     parted
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv'
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv_open'
+  ../libparted/.libs/libparted.so: undefined reference to `libiconv_close'
+
+Since iconv functionality is needed unconditionally (not only when
+gettext is enabled), AM_ICONV needs to be added to configure.ac.
+
+Upstream status: sent to mailing list
+http://lists.alioth.debian.org/pipermail/parted-devel/2017-November/005131.html
