>Description:
Consider:
<header.h>
#include <iostream>
#include <string>

<test1.cc>
#include "header.h"

int main()
{
  std::cout << "Hello World!" << std::endl;
}

<test2.cc>
#include "header.h"

int main()
{
  std::string str = "Hello World!";
  std::cout << str << '\n';
}

After a 'g++ -x c++-header header.h', I get:

-test1.cc
