Yes, that is a good idea IMHO.  At the same time let's get rid of the
CONFIGURE-AC argument we're suggesting there but which didn't work right
anyway.  But let's not actually change the functionality, so that what
works continues to.  (A bit fragile, I know; I think the long term goal
should be to implement that functionality properly, in all autotools;
but I don't want to do that now.)

OK to apply?  Do you think we need to announce this change in NEWS?

Cheers,
Ralf
