Please no, these older versions of gcc are extremely useful to C++ 
programmers. The differences between one version of gcc to the other 
often have a significant impact over C++ code compatibility (much more 
so than for C). I spent a lot of time trying to fix a K-3D build issue 
related to the C++ boost library unhappy with g++ 4.4. It was very 
useful to have g++34 available to fall back on a working case.

I actually maintain "compat-gcc-32-c++" here at work and am considering 
submitting it for review: gcc 3.2 is even more important to C++ 
programmers as it works with libstdc++.so.5 (while following versions 
need libstdc++.so.6). Fedora provides 'compat-libstdc++-33' for binaries 
compatibility, but if you have an old binary library that uses 
libstdc++.so.5, you can't use it without g++32.
