For freebsd, almost nothing since it's all elf and uses the gnu tool chain largely as is. I've already done a first pass test of it and the results were extremely promising. Maybe the next release can have it. For OSX, it's more work since it's not elf based and they diverge fairly far from a pure gnu tool chain. At a minimum, the ability to write out macho 64 bit .o files. Probably more, but hopefully not a lot more. It'll be a lot easier to assess after that part is done I suspect. Later, Brad
