This has nothing to do with it. We are talking about bootstrap times of compilers with roughly equivalent functionality. They both compile C, C++, and fortran. You can assume our backends and frontend are comparable in terms of functionality (they actually are, though not equivalent in performance generated by that functionality, but in time taken by each functional part they are). As i've said, we've already excluded the running time for the functionality we don't have (interprocedural middle end). --Dan
