The title is misleading, and the article is hard to read.
The central complaint seems to be that the language shoot-out uses the 'go' compiler. This doesn't seem surprisingly, seeing as this is what the go website tells users to use.
There is however a gcc frontend for go, complete as of July and still not in many distributions (this isn't a go problem, man distros haven't updated yet to gcc 4.7.1).
So the real headline should be 'Computer Language Benchmarks uses google's go compiler, gccgo is faster'
