+From: martin f. krafft <madduck@debian.org>
+Subject: Remove -Werror from compiler flags
+
+-Werror seems like a bad idea on released/packaged code because a toolchain
+update (introducing new warnings) could break the build. We'll let upstream
+use it to beautify the code, but remove it for out builds.
