* coff-aux.c: New file. * hosts/m68kaux.h: New file. * config.bfd (m68*-apple-aux*): New target. * configure.in (m68*-apple-aux*): New native host. (m68kaux_coff_vec): New vector. * configure: Rebuild. * targets.c (m68kaux_coff_vec): Declare. * coffcode.h (bfd_coff_backend_data): Add field _bfd_coff_link_add_one_symbol. (bfd_coff_link_add_one_symbol): Define. (compare_arelent_ptr): New static function if TARG_AUX. (coff_write_relocs): If TARG_AUX, sort the relocs. (coff_write_object_contents): Set A/UX aouthdr magic number. (coff_link_add_one_symbol): Define if not defined. (bfd_coff_std_swap_table): Initialize new field. * libcoff.h: Rebuild. * cofflink.c (coff_link_add_symbols): Call bfd_coff_link_add_one_symbol rather than _bfd_generic_link_add_one_symbol. * coff-m68k.c (COFF_PAGE_SIZE): Don't define if already defined. * coff-alpha.c (alpha_ecoff_backend_data): Initialize new field. * coff-mips.c (mips_ecoff_backend_data): Likewise. * Makefile.in: Rebuild dependencies. (BFD32_BACKENDS): Add coff-aux.o. (BFD32_BACKENDS_CFILES): Add coff-aux.c.
