------- Additional Comments From kargl at gcc dot gnu dot org 2005-03-14 06:34 ------- While I can agree that REAL DO loop indices should cause a warning, it is incorrect to call this feature an extension to the language. Fortran 77 permitted such indices. Fortran 90 declared them to be obsolescent, which means the feature was permitted. Fortran 95 finally deleted them.
