I've never edited any of my sources on the Mac. No, it's in app.cpp. Any decent text viewer will show you where - "less" for instance. Look for the two #include lines which it doesn't wrap correctly. > IMO it would be best if GDB would handle line separators equally as GCC. > So the behaviour would be consistent an easier understandable by the user. I think this behavior should be removed from GCC, personally. But GCC isn't the only compiler used by GDB; if you play this sort of game with line endings, you're going to lose on some combination anyway. -- Daniel Jacobowitz
