It isn't. I'm pretty sure you are comparing different compileres, i.e. your
"gcc" might be pgcc, while your "g++" might be gcc-2.7.2 or sth. else. (Have
you compiled it yourself or installed both packages?).

Yes. Given some compiler switches, you should be able to get smaller
programs then 2.7.2 (-m486) as well. (try -O2 -Os).
