The gfortran page https://gcc.gnu.org/wiki/GFortran says, "Gfortran is the name of the GNU Fortran project, developing a free Fortran 95/2003/2008 compiler for GCC, the GNU Compiler Collection." Since Fortran 2018 features are being added, I suggest that 95/2003/2008 be replaced by 95/2003/2008/2018. Or maybe just 2018, since Fortran is largely backwards compatible and compilers do not remove the ability to compile even deleted features.
I thank the gfortran developers for a tool I use daily. Vivek Rao
