Yo Enrico,

emerge -aev world

should do the trick.

For a change of CFLAGS. For USE changes you only need to rebuild the
affected packages with

emerge -uavDN world

Ok. Thanks.

What does 

    emerge system
    
exactly do ?

system is an alias for a bunch of core packages.  I forgot where it's
defined.

That's the profile. This is cascading. The start point
is /etc/make.profile (check what the symlink points to) and downwards
the path (in fact, according to the "parent" files, i.e. "base" is the
most upward level atm.) to $PORTDIR/profiles in the "packages" files.
Note that the rest is up to the dependencies. The profile is in fact a
bunch of default settings, default masks and a default "system" package
list.

So "system" represents the base system ? 
And "world" represents evrything I emerge'd manually ?

World also includes system.

The packages mentioned in the file /var/lib/portage/world.
were emerged by you manually.  An
   emerge foo
also emerges packages that are required by foo.  These are not,
however, placed in the world file by this emerge.
