* config/obj-multi.h: Include obj-elf.h if OBJ_MAYBE_ELF. Reformat.

(obj_frob_file): Test for null pointer.

(OBJ_COPY_SYMBOL_ATTRIBUTES): Here too.
|

(OBJ_PROCESS_STAB): And here.

(elf_obj_sy): Remove

* config/obj-elf.h: #ifndef everything defined in obj-multi.h,

except OBJ_PROCESS_STAB, which we #undef for ecoff.
|

(elf_obj_sy): Remove #ifndef OBJ_SYMFIELD_TYPE.
|

|

* config/obj-coff.c (no_func): Remove.
|

(coff_format_ops): Change occurrences of no_func to 0, as we test
|
||||
for 0 in obj-multi.h.
|
||||
|

* configure.in: Enable bfd for i386-coff when primary target is
|

bfd. Enable i386 elf,coff emulation support. Don't set
|

USE_EMULATIONS=1 or te_file=multi unless there is more than one

emulation to support.
|

*configure: Regenerate.
