Yes, g++ has been entirely rewritten and produces more bloated code... I
guess mainly because they use bloated header files (their system =
extensions
must be collected to few header files).

Only the optimisation switches.

I think we can be sure that as time passes things will get improving. =
That's
all. :-)
