my mistake.  I thought I had seen traffic on binutils that this was the
case.  sorry for the confusion.

he may not see any reason to support them, but we certainly have one.
if the work can be done, I don't see how he could object to getting the

objcopy really seems the more correct solution.  copying between
differing formats is what it's designed to do, no?

I guess I can at least take a cursory look at it...  I need an excuse to
get my 2100s back up and running.  ;)
