While I was looking at all the compilation warnings, I would often do "make 2> /tmp/warn" and look at that file, which does contain all the warnings. However, it also contains the bits where we output informational progress messages from Emacs, and that seems sub-optimal. Would it be a good idea to have some way of specifying whether `message' should output on stdout instead of stderr? Like (let ((standard-error 'stdout)) (message "This is not an error message")) or... something. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
