Test case by Dick Hendrickson, gfortran tested by Ron Shepard.

The executable is OK, but gfortran prints a bogus warning:
  Warning: '&' not allowed by itself in line 2

(The run-time result is:
 Print rather a lot of ampersands &&&&&&&&&&&
)

  PRINT *, 'Print rather a lot of ampersands &&&&&
   &&&&&
   &&&&&'
   end
