This is what we are currently using to indicate C++0x mode. Ie,
-std=c++0x/__GXX_EXPERIMENTAL_CXX0X__.

There is no fine-grained control just for rvalue references, a la
-fexceptions/__EXCEPTIONS.

I don't need fine-grained control. I just need a way to detect rvalue reference support. If -std=c++0x guarantees rvalue reference support, I can use __GXX_EXPERIMENTAL_CXX0X__ for that.
