Because the changes introduce more elaborate M4 constructions overall, relying more on correct user-side quoting than was needed before. At least that's my impression, I do not have hard data for this. Don't get me wrong, I'm not trying to criticize. The move to shell function is worth much more than trying to forever support broken user scripts. However, it should be very clear that the next Autoconf release quite necessarily is a less stable one for users than the last one, even if it all it causes is to uncover some more latent issues in user's configure.ac and .m4 macro files. Long-term, that can only be a good thing. > Anyway, shell functions will have to be mentioned in NEWS. Certainly. Cheers, Ralf
