patch from Dave Johnson <djohnson@sw.starentnetworks.com> via Debian #433543

When running 'ifconfig' it will not show any IPv6 addresses for
interfaces that have an ifindex > 255.

Because the kernel will increment the ifindex every time an interface
is added or removed, it is not necessary to have 256 interfaces at
once, just creating 256 interfaces since system boot and they will no
longer show IPv6 addresses.

This is due to an improper fscanf() maximum range argument.  Patch to
fix the problem is below.

Example:

st34:~# ip addr list dev eth1.110
268: eth1.110@eth1: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc noqueue
    link/ether 00:e0:81:2a:0d:2d brd ff:ff:ff:ff:ff:ff

    inet6 fe80::2e0:81ff:fe2a:d2d/64 scope link
       valid_lft forever preferred_lft forever
st34:~# ifconfig eth1.110
eth1.110  Link encap:Ethernet  HWaddr 00:E0:81:2A:0D:2D

improve dist target: include compiled gettext files, exclude scm files, and always prefix the paths in the tarball with the full versioned name

interface slip: cast keepalive/outfill to unsigned long to fix warnings on 64bit hosts -- no functional changes since these only have an 8bit range anyways

The rewrite of if_readlist() on 28 Jun 2003 broke the function when the
proc interface isn't readable.  Have if_readlist() return an error only if
both if_readxxx funcs failed.  This fixes Gentoo 238363.

enable -fno-strict-aliasing until the code base gets a hefty clean up to fix all of the strict aliasing problems

The local include trees no longer need -idirafter semantics, so use the
normal -I flags to avoid random cruft on users' systems.  This fixes Gentoo
#283759 where user had local headers named the same as the net-tools local
headers, but the toolchain defaulted to the system paths due to -idirafter.

touch up build system to respect normal toolchain env vars rather than requiring people to set random custom ones

The recent patch to add udplite support introduced a typo in the udp name.
This fixes Gentoo #282794 and Debian #545328.  Originally reported by
