[cfe-dev] clang finds errors in its own header files

[paul via cfe-dev]

Hi James,

Thanks,

I do include the -std=c++11 as a habit.

I have been trying all afternoon to get this to work.

I am wondering now if there is a step missing which describes the target 
OS? Xcode links to a number of SDK's when producing OS X Bundles ( 
test.app ).
