You aren't serious, are you?  Did *you* read the fucking manual *and* 
comprehend it?  Methinks not...upgrading from 3.3 to 3.4 in a 
pre-existing install != installing from a fresh stage.  First, running 
bootstrap.sh with the new gcc version unmasked would completely get rid 
of the "-e system" part of that howto, since that would force your 
toolchain to rebuild itself.  Second, the -e world is to ensure that 
your full install (which surely has plenty of c++ apps outside of 
system) is linked against the libstdc++ of the new gcc.

Remember, in a pristine stage3, system == world.  Therefore, your 
"comparison" is really telling folks to emerge -e system twice in a row. 
  Doing bootstrap.sh followed by 'emerge -e system' from a stage3 is the 
same thing as doing bootstrap.sh followed by 'emerge -e system' from a 
stage1...sorry to burst your bubble.  So again, idiocy and FUD.
