I've merged in some network interface code from JanosVM. What seems to happen
is that HAVE_GETIFADDRS is not set in config.h as apparently configure can't
find getifaddrs. That's all right on linux, that's what the replacement code in
ifaddrs_linux.c is for. But the replacement code seems to have trouble locating
some headers on your system.

The linux/* headers are linux includes. I've got them in /usr/include/ on my
system (Debian, ix86-linux). The netpacket header is part of GNU C library. But
I haven't tried cross-compiling kaffe, so I don't know what directories the C
compiler adds (or leaves out) automatically when cross compiling. I'd assume
that copying these directories to your /usr/local/m68k-linux/include directory
should work (but make sure you have the right headers for the right versions of
the kernel and libc on your target platform).

That's a bug. I'll look into configure.in to see what's happening.

I'm wondering whether netbsd would run on an emulator like UAE [1] or Aranym
[2]. (I'm not aware of a MMU patch for basilik II). That sounds like a better
option to me, especially with todays fast CPUs.

Or maybe you can ask someone on m68k-netbsd mailing lists to give it a try.
