Hi, I don't know who should be held responsible for the following bug (and if it's the right place to discuss about that) but: transform the line ends of the file given at the end into dos style ^M^J (I have to edit maintain compile and debug dos style source code). I'm using xemacs 21.2 beta 26 with mule enabled so that I can edit such files: the modeline shows ISO8:T. This file can be compiled with gcc-2.95 (older gcc's will not accept the \^M^J as a macro continuation). When you try to debug it with Meta-gdb the highlighted line is just not the good one (the line shift is the number of macro continuations). One more question: which variable should I tweak to change the color of this highlighting?
