This is probably more trouble than it is worth.  gcc-4 won't be fully 
ABI compatible with gcc-3.4, and you are likely to find bugs in gcc and 
various other packages, as gcc-4 hasn't been used to build a full distro 
yet.  How much trouble you see will depend on your target, which you 
didn't specify.

Unless you are in the business of making distros, or want to learn how 
to build a distro, it is best to stick with the compiler that your 
existing distro supports.

Also, it is probably a little early to worry about this, as the gcc-4 
release is probably still 2 months away.
