Just from your log it seems 3.3.1 is used, because gcc -v gives 3.3.1. On many systems, /usr/local comes before /usr in PATH. So if you have a version in /usr/local, it is usually the one that is loaded if you don't qualify with the absolute path.

You shouldn't delete 3.2, and in fact you should generally not remove the system-shipped gcc from your system.

If I don't interpret wrongly, because all of your libraries shipped in your RPMs were compiled using gcc 3.2, if you later on want to compile packages using these libraries, your gcc3.3 will not link those libraries unless they are recompiled using the new compiler. If you force remove gcc3.2 I guess you will break a lot of things. That's what I was told, and I need clarification on this too. gcc is not just another software package. It is the central component of any Linux and BSD systems that affects many parts of the system, and if that is not done carefully, you will likely wreck your system.

If you really have to stay with the latest compiler, use Debian unstable, because packages of the libraries compiled with that compiler will also be available with each compiler release. For example, the gcc version I have here is 3.3.2 with all necessary patches. That is by far the safest way to go.
