I'm using 2004.3 profile, and when I try to emerge gcc-3.4.2-r1 it fails to compile.

Have you upgraded your libstdc++-v3 already? I think it tries to go after GCC but might need to go first or something.
I (fortunately for me) had no problems compiling gcc-3.4.2-r1 from gcc-3.4.1-r2. libstdc++-3.3.4 ~amd64
I had a similar problem, but with gcc-3.4.1-r2. I solved (VIA Lv's Suggestion) <lv> lares, FEATURES="-sandbox" USE="multilib" emerge gcc portage <lv> portage to get you a 32bit sandbox <lv> then you dont need to disable it ever again
seems ok now
