--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- > I understood -pedantic such that it gives warnings if a construct > does not match the Fortran standard. Currently, it seems to be partially > used such but also used to warn for non-Fortran-95 (!) constructs. While experimenting with pr88190 it is not how it works. The current behavior is more or less -std=f* gives errors for all the gfortran extensions with/without -pedantic(-errors), -std=gnu (default) accepts (most if not all) gfortran extensions, using -pedantic gives warnings for (some) extensions that do not give without it (see gfortran.dg/comma_format_extension_4.f), -std=legacy accepts all gfortran extensions without any warning, unless -pedantic is used. > This should be used in conjunction with -std=f95, > -std=f2003, or -std=f2008. is definitively wrong.
