Correct me if I am wrong, but doesn't the gcc ebuild in fact use the "make bootstrap" method of compiling gcc? - that is: 1. compile with installed compiler -> stage1 2. compile with stage1 compiler -> stage2 3. compile with stage2 compiler -> stage3 4. compare stage2 and stage3 and install stage3 if they are the same If I am right, doesn't it mean that the whole "emerge -e system" step is pointless? Couldn't one just do "emerge -u gcc" and then "emerge -e world"? Or am I being stupid?
