I decided to be braver and use the completion mode in emacs, which, if I understood things correctly, relies on the clang compiler driver. The problem I have is that when I use the clang compiler driver I it doesn't seem to be able to locate the standard library:

clang -fsyntax-only hello.cpp -###

Then copy the clang -cc1 command this prints.
