That's strange. We already have a bunch of #if's for NetBSD. You meant
we need more to make it compile?

You are right. We've thought about this as well and we're going to create
our own ELF include files (including arch specific ELF definitions),
similar with Binutils' include dir, I guess. However some #if's will still
be necessary.
