Jens,
I've applied your patch to 0.08 and sent the resulting file to Keith
Peters, the gentleman that submitted the MAC patch for 0.08 which
resulted in the release of 0.09
Your patch breaks on the MAC darwin platform.
I wonder if you two might correspond and try to work out the
differences. I only have SUN and Linux boxes to work on and can not make
a meaningful contribution to this bug fix.
Keith's comments follow.

I guess macs have trouble setting MTU on lo0.
But it get's what I need from it done.
I also get some spurious "NI_ACCESS : Can't assign requested address"
messages as well which are similar to the test failure message. The appears
to be caused by the fact that some of my interfaces don't have addresses but
have AF_LINK setup properly. I don't know enough about the ioctl to be able
to debug that one further. And I don't know how to make my code aware of
whether or not the address would exists until calling "->address" and
checking for undef.
Just so you know how weird the ifconfig on a mac is...
