On Windows G++ supports exceptions. I have two questions: 1) Do you know how they do this? Do they have a license? If they have a licence why don't LLVM people too have it? 2) Why isn't LLVM just copying that part of the GCC code? If a true copy is not possible, why aren't copying the code with enough cosmetic changes? (A good amount of time ago I did believe that the main purpose of the Open Source idea was to copy source code between projects, to avoid reinventing things. I was so wrong.) Bye, bearophile
