	* listing.c: Call xmalloc, not malloc; don't declare malloc.

	* Changes to support SCO 3.2v4:
	* read.c (s_align_bytes, s_align_ptwo): If not SEG_DATA or
	SEG_BSS, fill with NOP_OPCODE.
	* config/i386coff.mt: Add opcode/i386.h to TARG_CPU_DEPENDENTS.
	* config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
	using ZERO_BASED_SEGMENTS.
	(fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
	never set segment address for SEG_E2 (.bss) and don't write out
	SEG_E2 contents.  Set .init and .fini sections to STYP_TEXT.
	(obj_coff_endef): Don't merge labels or symbols awaiting forward
	definitions, and don't merge tags with non-tags.  Check for .bf
	rather than just checking whether the second character is b and
	the third character is f.
	(obj_coff_val): gcc can generate values which we don't handle
	correctly; discard information for now, since it only affects the
	debugging information.
	(tag_find_or_name): Don't insert tags in the symbol table.
	(yank_symbols): Don't merge labels.
	(write_object_file): Don't define SUB_SEGMENT_ALIGN if it is
	already defined.  Fill subsegments with NOP_OPCODE, not 0.  Don't
	set segment address if ZERO_BASED_SEGMENTS.
	(obj_coff_section): Accept and ignore a trailing quoted string, as
	used in AT&T i386 syntax.
	(fixup_segment): Take segment as argument.  On the i386, adjust PC
	relative addends by the segment vaddr.
	* tc-i386.h: Define SUB_SEGMENT_ALIGN.
	* tc-a29k.h: Define ZERO_BASED_SEGMENTS.
	* tc-i386.c: (i386_operand): If I386COFF, accept any segment type.
