Yes, that's right. In this commit I assume parser has already accepted the 
blocks.

We currently accept them if -fblocks is passed. I think we should also accept 
blocks by default with CL2.0. But I am thinking not to restrict passing 
-fblocks with earlier CL version. This way it's possible to enable them with 
earlier standards if whoever does it knows what it's needed for. We could give 
a warning in this case. What do you think?

However, I wouldn't block this patch on it, as I wouldn't commit them together 
anyways. But I am happy to prepare a separate patch.
