Urgle.

Ah well, worth a crack Nigel. I looked at removing the generation of
relocation info in the pe-dll emulation code, but from what I could see no
objects would get copied into the output if I did that :]. So I need a
replacement set of copy-object logic that doesn't do relocation.

Yeah - at link time all things are possible. I'll drop this for now, and
when I have a chunk of time to do more than trivial hacks, I'll bring it up
on binutils and see what the correct approach is.

Cool - they are orthogonal though (:]) so it wouldn't make a difference.
