       3     -H is used because cpp might confuse the issue by optimizing out
       4     #line markers.  This test only passes if the headers is read
       5     twice.

       7     The disgusting regexp in the dg-error line, when stuck into
       8     dg.exp's compiler-output regexp, matches the correct -H output and
       9     only the correct -H output.  It has to be all on one line because
      10     otherwise it will not be interpreted all in one unit.  */
