There is already a newline after it. What does the Standard say?

Hi Neo,
--- Foo.h ---
#ifndef Foo_H_ONCE
#define Foo_H_ONCE
extern int MyFoo;
#endif // Foo_H_ONCE<NO-NEWLINE>
--- --- ---
The "<NO-NEWLINE>" is a meta to indicate that there is no newline at the end
of the file.
--- Foo.cpp ---
#include "Foo.h"
#include "Bar.h"
...yada yada yada...
--- --- ---
Is Bar.h supposed to be included? Or is the comment-to-end-of-line at the
end of Foo.h supposed to comment it out?
The behavior is undefined.
HTH,
