7// We will include two header files:
8// one that uses `#pragma once`, and
9// one that doesn't.
10//
11// The first file defines a function `foo()`,
12// and the second defines a macro `BAR`

14#include "pragma-once-a.h"
15#include "pragma-once-b.h"
16
17// We will include the files again, and
18// before we do so we need to undefine
19// the macro from the second file so
20// that it doesn't get a redefinition diagnostic.
21//
22#undef BAR
23//
24// We don't do anything about the function
25// in the first file, because we expect
26// the `#pragma once` to cause it to be
27// ignored on this second time.
