What I mean is that a package that does not compile under clang needs to include the above fix for xcode-4.2 if your automatic switch to clang is implemented. But then it will probably no longer work on 10.5 and on 10.6 with xcode-3.2. You would need one info file for xcode-4.2 and another one for xcode<=3.2. I don't see how this is possible inside the 10.4 tree. -- Martin ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
