        * trans-array.c (gfc_trans_g77_array): If the variable is
        optional or not always present, make the statement conditional
        on presence of the argument.
        * gfortran.h : Add symbol_attribute not_always_present.
        * resolve.c (check_argument_lists): New function to check if
        arguments are not present in all entries.

        PR fortran/30084
        * module.c (mio_component_ref): Move treatment of unique name
        variables, during output, to fix_mio_expr.
        (fix_mio_expr): New function that fixes defective expressions
        before they are written to the module file.
        (mio_expr): Call the new function.
        (resolve_entries): Call check_argument_lists.
