I bought a new laptop with pentium-m CPU and installing gentoo on it
from stage1.

The gcc version on livecd (2004.3) is 3.3.x, but I want use
-march=pentium-m in my CFLAGS and gcc 3.3.x doesn't support it.  So I
add the following line in /etc/portage/package.keywords:

sys-devel/gcc ~x86

and run bootstrap.sh with the default CFLAGS -mcpu=i686, and get gcc 3.4.4.

Then I change my CFLAGS to -march=pentium-m and execute emerge -e
system as Handbook says.  But it failed when emerging gcc-3.3.6
because of unknown value for -march=.

gcc-3.3.6?  I don't need it! I have gcc-3.4.4 unmasked!

I check the package list of emerge -ep system, and find both gcc-3.3.6
and gcc-3.4.4 are to be emerged. Why? How can I get rid of emerging
two versions of gcc?

I'm usually annoyed by IDEs because, for instance, they don't use VIM
as an editor. Since I'm hooked to that, all IDEs I've used so far have
failed to impress me.
