But why do you need the alternatives? We've done without them
perfectly well.

I see. It must have been something about the old Cygnus configure,
then. Perhaps some old option it used to accept that started with
--cach too. No longer relevant. The change from --cache to --c is
ok. I still don't see the point of the alternations, except perhaps
for documentation purposes, but there's no reason to make the regular
expressions trickier to document the options; comments will do better.
