Got it. I have something that works for my product (rh8 based, wine
20050419). I'll keep an eye on this when we get around to upgrading. 

I think what makes most sense is to use if_nameindex() unless it is
known not to work, using if_indextoname() only as a work around. Seems
like this could be done with a config flag, given that the only time
you'll see the problem is on a system with the old libc which means that
the wine was also built against the old libc. So a compile time flag
would do the trick. Does that sound right, or does it have to be
detected at runtime?
