an application that relies on non-posix getopt behaviour should come 
with a configure check and use an alternate impl if the getopt detected 
is not compatible.
almost any program does so already, but for those that don't (like 
iptables) you can use https://github.com/rofl0r/gnu-getopt (tarball 
available on sabotage mirror, or in downloads section of the page).
this bundles the netbsd getopt into a standalone library that can easily 
be linked to programs.
