Correct me if I am wrong, but doesn't the gcc ebuild in fact use the |
| 12 |
"make bootstrap" method of compiling gcc? - that is: |
| 13 |
1. compile with installed compiler -> stage1 |
| 14 |
2. compile with stage1 compiler -> stage2 |
| 15 |
3. compile with stage2 compiler -> stage3 |
| 16 |
4. compare stage2 and stage3 and install stage3 if they are the same |
| 17 |

If I am right, doesn't it mean that the whole "emerge -e system" step is |
| 19 |
pointless? Couldn't one just do "emerge -u gcc" and then "emerge -e |
| 20 |
world"? Or am I being stupid? |
