Dear all, in Fortran 2018 a few intrinsics were extended and now support additional optional arguments. See PR 85836 for the meta-bug, and in particular:
96583 - get_environment_variable 96584 - get_command 96585 - get_command_argument with an optional ERRMSG. How are we going to deal with this? If we do not want to break the existing ABI, so that we can link gfortran-13 and gfortran-14+(?) compiled code, we need to keep _gfortran_get_command_i4 & friends, and introduce new library functions that are able to handle the new requirements. Do we have recommendations for a naming scheme? Like _gfortran_F2018_get_command_i4 or _gfortran_get_command_F2018_i4, or better? Would it be sufficient to update gfortran.map suitably? Or do we need to bump something else? And would that be fine, given that 14-development is in stage-3? Or rather wait for the next stage-1? Thanks, Harald
