I had thought a solution would be to have the link create relaxed b.out format, and convert it to COFF using objcopy. But someone told be this would lose the symbols, thus rendering the file hard to debug. Thanks for the feedback though Ian. Is anyone else out there having the same problem/working on a rewrite/found a different solution? Thanks, Michael
