Although it might work if Emacs is run directly from a Linux console, I d= oubt=20 whether it'd work in general. The ioctl needs a file descriptor, and whic= h file=20 descriptor should Emacs try? Stdout? Stderr? What if the output of Emacs = is=20 being sent to a file or pipe, and some other program later displays the t= ext? I'd like to see what GCC does before worrying about this too much. Also I= 'd like=20 to know why Alan sometimes sees block squares and sometimes diagonal line= s.
