Symbol referencing errors building hello world, sparc-sun-solaris2.11, gfortran-4.1.0

[John Wiggins]

I'm running into some problems compiling a simple hello world:

c
c   Hello, world.
c
     Program Hello

     implicit none
     logical DONE

     DO while (.NOT. DONE)
       write(*,10)
     END DO
  10 format('Hello, world.')
     END


% gfortran test.f
