Thats true. e.g. I could not build gcc 3.3.1 on my Fc4 box using GCC 
4.0. they also provide gcc 3.2 in FC4 distro
so if you use CC=/usr/bin/gcc32 it should invoke gcc 3.2 to build your 
compiler which should build fine.

I could build gcc 3.4 with GCC 4.0 without any problems.

Same for binutils. You might find some problems building 2.15 using GCC 
4.0. 2.16 works fine.
