you're looking at bootstrap wrong ... it forces a few native packages to the

in this case, bootstrap emerges gcc and portage picks the best one ... 
gcc-3.4.4

if a user wants gcc-3.3 but not gcc-3.4, then it's their responsibility to 
mask it accordingly via /etc/portage

i dont know what you mean by "proper"

at any rate, this will all "fix" itself when 2006.0 is released
