Is there a way to suppress Intellisense errors when using C++11 features specific to November 2012 CTP?

Go to:

Tools->Options->Text Editor->C/C++->Advanced->Intellisense

and set "Disable Error Reporting" to true.

I'm quite confident you cannot do that.

The CTP independently updates the compiler only, not Intellisense. Intellisense is based on EDG's front-end, which the CTP does not update (even regardless of the CTP, Intellisense and the compiler might disagree at times because of this). See also this Q&A on SO for a clarification.

You can, of course, disable Intellisense completely, but I don't think that's what you were asking for.
