(1) I've shown you the relevant text from the Fortran 95 standard
    document, which gfortran is attempting to implement.

(2) You wrote "Be sure that the last sentence does not mean that
    the width should be really zero :)"

    The text I quote from F95 standard clearly shows that the 
    width can't be zero.  There is no guessing.  Yes, I see your
    smiley. 

(3) Look at 10.6.1(6) in F2003.
