* app.c, config/tc-*.c: Don't include read.h, since it is already
	included by as.h.

	* These are based on patches from Minh Tran-le
	<mtranle@paris.intellicorp.com>.
	* configure.in (i[34]86-ibm-aix*): Accept i486 for host.  Use
	obj_format coffbfd and gas_target i386coff for target.
	(i[34]86-*-isc*): New host (uses sysv).
	* config/i386aix.mt: Removed (no longer used).
	* config/mh-i386aix (RANLIB): Use true rather than /bin/true.
	(MINUS_G): Removed.
	(LDFLAGS): Added, defined as -shlib.
	* config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
	* config/te-sco386.h (LOCAL_LABEL): Don't define.
	(DOT_LABEL_PREFIX): Define.
	* expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
	name rather than L0\001.
	* read.c (s_lcomm): Make a frag in SEG_BSS rather than using
	local_bss_counter.
	* symbols.c, symbols.h (local_bss_counter): Removed.
	* write.c (write_object_file): bss no longer uses
	local_bss_counter.  Pass correct data and bss size to
	VMS_write_object_file.
	* config/obj-vms.c (VMS_write_object_file): Accept bss size as
	argument, rather than using local_bss_counter.
	* config/tc-m88k.c (s_bss): Don't use local_bss_counter.
	* config/tc-sparc.c (s_reserve): Don't use local_bss_counter.
	* config/obj-coffbfd.c (had_lineno, had_reloc): Removed.
	(size_section): Restored sanity check.
	(do_relocs_for): Base section address on s_paddr rather than
	computing it.  Adjust a29k R_IHIHALF special case to account for
	section paddr (used to require paddr to be zero).  If there are no
	reclos, set s_relptr to 0.  Set relocation size in object_headers.
	(fill_section): Always set s_vaddr here, removing
	ZERO_BASED_SEGMENTS case.  Force s_scnptr for bss to 0.  Don't set
	NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
	Set STYP_INFO for .comment.
	(coff_header_append): Use object headers and H_{SET,GET}_* macros.
	Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.
	(crawl_symbols): Handle 8 character section name correctly.  Use
	H_{SET,GET}_* macros.
	(do_linenos_for): Set lineno size in object_headers.
	(write_object_file): Use H_{SET,GET}_* macros.  Don't bother to
	set s_vaddr here.  If string_byte_count remains 4, set it back to
	0, and only write strings out if there are some.  Call
	fill_section before do_relocs_for and do_linenos_for.
	(obj_coff_section): Handle optional quoted second argument giving
	section characteristics.
	(obj_coff_bss): Added to handle .bss.
	(obj_coff_ident): Added to handle .ident (puts string in .comment
	section).
	(obj_coff_lcomm): Put common symbols in .bss, not .data.
	(fixup_mdeps): Change to segment.  Call frag_wane after
	md_convert_frag.
	(fixup_segment): Explicitly check S_IS_COMMON before making 386
	adjustment (already happened only for common symbols, but this is
	clearer).
	* config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
	* config/tc-i386.c (s_bss): Don't use if I386COFF.
	(md_pseudo_table): Ignore .optim and .noopt.
	(tc_coff_sizemachdep): New function.
	* config/tc-i386.h (REVERSE_SORT_RELOCS): Undef, for SVR3
	compatibility.
	(LOCAL_LABEL): Removed definition.
	(DOT_LABEL_PREFIX): Defined.
