The compiler only runs for less than 15 seconds. It happens only when the error message is a bit big. ( > 50Kb). It is instantaneous with emacs-22.3. I don't have to wait at all. I'm using multi-tty, but I can reproduce it without server-start. I also use CEDET, but the behavior is the same without it. Sometimes the error message is *much bigger*. And that makes it unbearable to wait. Is this behavior known? Is it considered a bug? Is there anything I can do (aside from not using compilation mode, or using emacs v22.3)? Both emacs (emacs-23 and emacs-22.3 are compiled for console and used through ssh). -- Felipe Magno de Almeida
