The IPv6 patch was obtained from the kame repository and has been
been writen by KIKUCHI Takahiro <kick@kyoto.wide.ad.jp>
Due to the whole mess with different patches it was necessary to include
both the IPv6 patch and patch-ssh-1.2.27-bsd.tty.chown in ${PATCHDIR}.
Since both patches modify the configure script it was also necessary
to rebuild it via autoconf from configure.in. I've decided to use
USE_AUTOCONF instead of including the re-build configure script in
${FILESDIR}

|
