For GNU/kFreeBSD, the milestone (upstream) libtool version are
1.5.2-1 - earlier does not support GNU/kFreeBSD at all
1.5.24-1 - fixed anon_versioning bug for GNU/kFreeBSD and hurd (rarely
hitted)
That should we advise people to do in the description of the tag?
Obviously if they have an active upstream, asking them to update the
libtool files is the best way to go, but what if upstream is inactive?
Should we encourage them to update the libtool files in the Debian
package or should they try to do a minimal patch, like you send them
out?
