I discovered (by accident, actually) that there was no need to run the bootstap target at all as long as m4 got built before lex during the bootstrap-tools stage, so that's the fix I applied, and it was sufficient to build current and stable-10 on a stable-8 build host. I suppose at this point the bootstrap target, and all the pre-generated files it copies, could be deleted. Unless they're serving some other purpose I'm not aware of, like maybe some folks have a need to run that target manually. -- Ian
