The point is that when the output goes to a file, it has to be buffered, otherwise you access frequently the disk. If your disk is networked, you can understand what a bottleneck you are imposing. Things are different when the output goes to screen. I think that you should find a way for fixing the screen output on native Windows (if it really need be; I see that only the output from configure is irritantly delayed, but otherwise latex runs are reported in a quite timely way). Heck, one of the reasons I use cygwin is that of avoiding these unexplicable idionsyncrasies. -- Enrico
