--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
Now I wonder, since libgfortran doesn't change itself, why the fortran FE does
not properly change _gfortran_pack to resolve to _gfortran_pack_r8?  IIRC there
was a related PR requesting those -fdefault-* flags to simply reflect into the
AST of the current TU and IIRC that was done - but maybe handling of intrinsics
is missing?
