[gentoo-user] gcc 3.4.x --> 4.1.x : a couple of questions

["b.n." <brullonulla@gmail.com>]

Hi,

Quite late :), I'm going to do my homework, that is the loooong upgrade 
to gcc 3.4.x --> 4.1.x

The subject has been widely discussed, so I've just a couple of 
questions to be super-safe:

- I'm going to follow [1] (of course) and [2] (looks nice). Other useful 
guides?

- Is there a new incompatible GCC upgrade going to be unmasked? I see 
4.2 and 4.3 are hard masked, but if there is the suspicion they're going 
to be used relatively soon AND they are not binary compatible with 4.1, 
I may wait for those. When I did 3.3-->3.4, I waited long, and 4.1 
became stable after a week... :/

- Is it mandatory/highly advisable to recompile also the kernel, or can 
I postpone? In the first case, when it's better to recompile it (before 
all/after all)?

- Do I have to emerge glibc 2.4 first and gcc later, or I can have glibc 
emerged in the emerge -e system?

- Any other glitch/tarpit I must be aware of?
