Nah, doing an emerge -e world will give you exactly the same. Since the |
| 8 |
gcc compiler bootstraps itself on compile time, so, recompiling it |
| 9 |
again and again and again and again is pretty much useless. |
| 10 |

What does that mean? Well, the compiler first is compiled with your |
| 12 |
actual c compiler, and then, once it's been compiled, it automatically |
| 13 |
re-compiles itself using the produced compiler. So, if you do it again |
| 14 |
you are just wasting your time. |

That is, of course, unless you pass the --disable-bootstrap option |
| 17 |
to ./configure when compiling gcc, but as you all can see, it is not |
| 18 |
the case: |
| 19 |
|
| 20 |
# grep disable-bootstrap /var/portage/sys-devel/gcc/gcc-4.1.1.ebuild |
| 21 |
# |
| 22 |
|
| 23 |
It is a common and widespread misconception. Of course, you can |
| 24 |
still recompile gcc as many times as you wish, if that makes you happy. |
