Perhaps if he gave the specific problems he ran into, with the actual compiler output.
Indeed. He was just passing along what someone else sent to him. I expect rms himself does not have any more info :(. dropped support for the split-buffer code So Emacs has to have a forked regex forever? How unfortunate. But I do recall how much agony there was in the implementation with the split buffer, so I can't say I'm surprised. Thanks for all the info. Karl
