Subject: [PATCH] cargo-i18n: fix build with newer versions of Clang
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

cargo-i81n depends on the gettext-sys crate, which vendors a version of
gettext that fails to build with the default Clang in nixpkgs. Using the
packaged (“system”) gettext avoids the issue.
