This is the result of the design decision to write a C-wrapper around a 
userland binary and except the output to be in a unified, machine 
independent format.

I think we're kind of kidding ourselves suggesting that code of that 
nature isn't going to get ugly.

#IFDEF is your friend.  Talk to the Net-SNMP people.  They've mastered the 
art of platform-independent C on POSIX systems.

Right on FreeBSD it's -S, but they also have a -I of iface, as if you 
could ask your system to source traffic from an address not local to an 
source interface, or if you have multiple interfaces in the same subnet.

On NetBSD the option is "-I" ifaddr, no -S + I,

On OpenBSD it is "-I"

On Solaris it's "-i"

On Ultrix it's "-r"

On Darwin it's "-i" from FreeBSD 4.11
The option is not supported on OpenDarwin

The option is not supported on HFUX 11x

On AIX it's "-i"

On Linux its anyone's guess because there are 5000 distributions and they 
refuse to centralize source code repositories for many userland binaries, 
insisting, instead, on maintaining local patches and refusing to feed them 
patches upstream.

RHL9 is "-I"
Suse 10 is "-I"
Slackware does not support the option

Who really cares about the rest? They can maintain local patches ...that 
what they're most proficient at >:}
