If he is using Gentoo, then maybe he has done that already.

I really can't understand why some people seem to be constantly compiling
the linux kernel.
Guess how many times I have compiled the linux kernel in my life.

The one time you did it correctly?

Unless I'm remembering incorrectly, I think one common complaint in
the "big" industry about gcc is that it's a relatively slow compiler.
When you have millions of lines of code, and regardless of all the effort
you have put into minimizing the number of dependencies, there may still
be so many dependencies that even small changes to certain files can cause
enormous amounts of compilation. We are talking about hours at worst.
This can certainly be a real pain if you are simply developing and
debugging the software rather than compiling the release version of it,
so compiling speed is in this situation much more important than the
quality of the generated code, and AFAIK gcc just isn't up to the task
in enormous projects because it's so slow.
(OTOH, I have never read any benchmarks about the compilation speed of
different compilers, commercial and free. That would be an interesting read,
in fact.)

I haven't compiled it even once.

Certainly I've never found it "necessary" either. But then, I don't
really "get" what it does that you'd need to change...

Was using Gentoo. And I'm pretty sure they give you a GCC binary
pre-built. (How would you build anything else otherwise?) Also the C
standard libraries, possibly. I can't remember.
Hold on a sec...

...nope, no help there. ;-) It's hidden away in bootstrap.sh

Join the club, neither have I. :)

Constantly - naah. But when running Red Hat ('bout 1998-2003 oslt) and
Debian ('bout 2001-2008) something (variating from time to time,
naturally) in the packet kernels has either been made differently than
I'd like or left to be undone at all.
And somehow while using Gentoo compiling also the kernel just makes
sense ;).

Maybe now it is, I remember it used to be an incredible way to install
because you had to do *everything*. I've seen some newer releases that
script some things, though.
