--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-02-03 07:30:24 UTC --- As postscript: * A program which uses the CHARACTER* declaration is still perfectly valid Fortran 95/2003/2008. - Thus, you do not have to react on the warning, you should only avoid it for new code and could consider fixing it in the old code. * A Fortran compiler is required to diagnose obsolescent features. From Fortran 2008, Section 1.5: "A processor conforms to this part of ISO/IEC 1539 if: [...] (2) it contains the capability to detect and report the use within a submitted program unit of a form designated herein as obsolescent, insofar as such use can be detected by reference to the numbered syntax rules and constraints;" That's what gfortran does if one ask for it (-std=f95/f2003/f2008/f2008tr).
