* config/obj-coff.c (struct filename_list): Only define if not

	BFD_ASSEMBLER.
	(filename_list_head, filename_list_tail): Likewise.
	(c_section_symbol): Remove unused BFD_ASSEMBLER version.
	(obj_coff_endef, BFD_ASSEMBLER version): Don't set the debugging
	flag for C_MOS, C_MOE, C_MOU, or C_EOS symbols, since they should
	have a section of N_ABS rather than N_DEBUG.  If we do a merge,
	remove the new symbol from the list.
 	(obj_coff_endef, both versions): Call tag_insert even if there is
	an old symbol with the same name, if the old symbol does not
	happen to be a tag.
	(coff_frob_symbol): Check SF_GET_TAG, C_EOF, and C_FILE outside of
	the SF_GET_DEBUG condition.  Don't call SA_SET_SYM_ENDNDX with a
	symbol that will be moved to the end of the symbol list.
	(coff_adjust_section_syms): Always call section_symbol for .text,
	.data, and .bss.
	(coff_frob_section): Likewise.  Also, remove unused variable
