I know that. But what about the preprocessor?

This is not what I want. Usually, g++ and gcc call a preprocessor.
I found, that some configure scripts recognize g++/gcc-3.4 as the 
compiler, when I set the environment variables CXX and CC, but
they complain about /usr/lib/cpp, which is linked to version
3.3.x . 

In other words, they don't use /usr/lib/cpp-3.4 automatically
when using gcc/g++-3.4 . How can I change that?

Yes, Thats well known. But your answers refer to the compiler,
and I asked for the preprocessor!
