// The first run line creates a pch, and since at that point HEADER is not
// defined, the only thing contained in the pch is the pragma. The second line
// then includes that pch, so HEADER is defined and the actual code is compiled.
// The check then makes sure that the pragma is in effect in the file that
// includes the pch.
