* ecoffswap.h (ecoff_get_off, ecoff_put_off): Add ECOFF_SIGNED_32
and ECOF_SIGNED_64 to list ways to extract an offset.
(ecoff_swap_fdr_in, ecoff_swap_fdr_out, ecoff_swap_pdr_in,
ecoff_swap_pdr_out, ecoff_swap_ext_in, ecoff_swap_ext_out):
Update.
* elf64-mips.c (ECOFF_SIGNED_64): Define instead of ECOFF_64.
* elf32-mips.c (ECOFF_SIGNED_32): Define instead of ECOFF_32.
