A quick "grep -F '[-Wunused'" finds nothing, while "grep -F
'[-Werror=unused-but'" finds 34 packages:

 acpid                libaio                      mutter
 appmenu-gtk          libcrypt-openssl-x509-perl  network-manager
 axis2c               liblauncher                 network-manager-applet
 bamf                 libmaa                      network-manager-pptp
 btrfs-tools          libunique                   rampart
 crash                libvoikko                   trousers
 desktop-webmail      libwps                      u-boot
 elfutils             likewise-open               ubuntuone-client
 freetype             lockfile-progs              window-picker-applet
 ido                  maximus                     xen-3
 indicator-session    mdadm
 jigit                memcached
 
I'll start working from the beginning of the alphabet.

Thanks, Matthias.
