Benchmarks "Google has released a research paper that suggests C++ is the best-performing programming language in the market. The internet giant implemented a compact algorithm in four languages - C++, Java, Scala and its own programming language Go - and then benchmarked results to find 'factors of difference'."

Depends on the gcc-version.

I just double-checked: According to info:gcc the most recent version (4.6) has enabled -ftree-vectorize on -O3, but still not -funroll-loops.

Unrolling is only default enabled if you compile with profiling-data that helps the compiler to unroll the correct loops.
