What is the best way to install GCC 4.8 in Quantal Quetzal (12.10)? I am trying to explore it's improved diagnostic messages and compare them to Clang, so 4.7 will not do.

gcc-snapshot from the repository, PPA, or compile from source?

Also will it coexist peacefully with an install of gcc 4.7 on the same machine?
