--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Of course, if libgfortran plans to bump soname for GCC 14, that would be ok, but not ok otherwise (you could e.g. keep the old symbol as is and add a differently named entrypoint that used the new prototype). But, as I wrote, the size_t vs. integer(kind=4) difference isn't the only problem, the other is that the FUNCTION_TYPE created in the FE for the function has just 5 arguments instead of 6 for some reason.
