--- Comment #1 from Joel Sherrill <joel at gcc dot gnu.org> ---
Looking at the generated options-save.c, the first line of this method is
clearly incorrect in the cast on the RHS. It looks like a full declaration and
not a type. If anyone familiar with the magic in these files looked at it, I am
sure it is easy to fix.

/* Stream in target options  */
void
cl_target_option_stream_in (struct data_in *data_in ATTRIBUTE_UNUSED,
                            struct bitpack_d *bp ATTRIBUTE_UNUSED,
                            struct cl_target_option *ptr ATTRIBUTE_UNUSED)
{
  ptr->saved_custom_code_status[256] = (enum nios2_ccs_code
saved_custom_code_status[256]) bp_unpack_value (bp, 64);
  ptr->saved_custom_code_index[256] = (int saved_custom_code_index[256])
bp_unpack_value (bp, 64);
  ptr->saved_fpu_custom_code[n2fpu_code_num] = (int
saved_fpu_custom_code[n2fpu_code_num]) bp_unpack_value (bp, 64);
  ptr->x_target_flags = (int) bp_unpack_value (bp, 64);
}
