This is NOT the same issue. VC9 does not have the decltype keyword. 
We're not talking about typeof emulation. Please don't take us off-topic.

The issue is whether the decltype keyword is too broken on VC10 to 
define BOOST_NO_DECLTYPE. I think it /may/ be, so we should define it 
just to be safe, at least for 1.43.
