--- Comment #3 from Martin Köhler <martin.pleissa at web dot de> --- Even if the code compiled with the -fdefault-integer-8 option has some smell, due to fact that it is most likely legacy code, it would be nice to allow some workaround, which is portable over the Fortran compilers. I checked the flang-based compilers and it seems that there the integer size in the user defined IO functions chnage with their "integer-8" flag. Thus, to ensure the compatibility, having the user defined io working with integer-8 would be great. By now at least having a proper warning/error message that indicate this point would be helpful as well. Beside that, it is clear to me, that the legacy codes need to be restyled.
