eed2b804bf When incrementing through a SIOCGIFCONF list, enforce a lower limit of
sizeof(ifr->ifr_addr) for the variable length field ifr->ifr_addr.sa_len.
Otherwise the increment will be wrong in certain cases.

Obtained from:  Whistle source tree
For the record: Garrett Wollman <wollman@khavrinen.lcs.mit.edu> suggests
                SIOCGIFCONF should be dropped in favor of a sysctl mechanism.

ebe70c8f68 More egcs warning fixes:
o main returns int not void
	o use braces to avoid potentially ambiguous else

Note: The fix to natd is potentially functional in nature since I used
the indentation as the right thing rather than the struct semantics.
Someone more familiar with the code should double check me on this one.

59a7c61374 Upgrade (almost) to natd 2.0b1
- Transparent proxy support.
  - PERMANENT_LINK IS NOW OBSOLETE, use redirect_port instead.
  - Drop support for early FreeBSD 2.2 versions
  - If separate input & output sockets are being used
    use them to find out packet direction instead of
    normal mechanism. This can be handy in complex environments
    with multiple interfaces.
  - PPTP redirect support by Dru Nelson <dnelson@redwoodsoft.com> added.
  - Logging enhancements from Martin Machacek <mm@i.cz> added.

f627793d19 Make this work with the new alias library since, evidently, we're
not providing the backwards-compatability routines in libalias anymore
(which I think may have been a mistake).

27c20503c6 Reverse my previous change and use htons() on an int
instead of htonl() !

This results in the int a,b,c,d changing to b,a,c,d,
but as it's subsequently coerced to a u_short, the
ultimate answer is correct.

If this isn't fixed properly soon (by the author) I'll
have a look at it again.
