True. It's a mess. I *know* it's an unsolvable mess, so why do I try to
sort it? (Don't answer.)

Yes, I think you are probably right. Sigh.

OK, I'll try to learn some more about Autotools - this does have to be
addressed somehow, unless we say "If you want to cross-compile, you must
not set --enable-rebuild-chartables; if you need other character tables,
you can build dftables.c independently and run it manually before you do
the real build." I could live with that.
