This patch only | makes decltype available when the experimental C++0x mode is enabled. | | Tested i386-apple-darwin8.8.1, no regressions. | | Okay for mainline?

Thanks for taking the time to implement this.

Procedural comments: Following the policy we all agreed on not so long ago, I believe the implementation should be in only after adoption in the WP (which is next meeting in Oxford, April 2007).

I realize I'm co-author of the proposal and you're just helping. But, I believe the policy holds for everybody :-)

I'd send more technical comments later.

Thanks!
