+Subject: [PATCH] Only add "iconv" to the .pc file if needed (#1825)
+
+Hi,
+
+Thanks for writing and maintaining libarchive!
+
+What do you think about this trivial change that does not add "iconv" to
+the pkg-config file's list of required packages unless it is actually
+needed? On at least Debian GNU/Linux systems, the iconv(3) function is
+part of the system C library and there is no Debian package that
+installs an iconv.pc file, so I had to make this change to the Debian
+package of libarchive.
+
+Thanks again, and keep up the great work!
+
+G'luck,
+Peter
