* as.h (rs_dummy): Define.
* symbols.c (symbol_X_add_number): New function.
* symbols.h (symbol_X_add_number): Declare.
* stabs.c (aout_process_stab): Tidy symbol frag setting.
* read.c (assign_symbol): New function, split out from s_set.
Use symbol_find_or_make. Leave fr_type of dummy frag as rs_dummy.
Fix COFF hacks for multi-emulation gas.
(s_set): Call assign_symbol. Remove "register" keyword.
(set_zero_frag): New function.
(pseudo_set): Always check for assignment to section syms.
Always set segment and frag of symbol, and likewise extern for
aout/bout. Handle assignment of sym=sym+/-const specially. Don't
special case exp.X_add_number non-zero for O_symbol expressions.
(equals): Use assign_symbol.
(parse_args) : Accept new --gstabs+ option, and set `use_gnu_debug_info_extensions'.
(show_usage) : Document --gstabs+ option.
* as.h (use_gnu_debug_info_extensions) : New extern declaration.
* stabs.c (stabs_generate_asm_file) : If `use_gnu_debug_info_extensions' is set
add the compilation directory to the stabs debug info.
* doc/as.texinfo : Document --gstabs+ option.
* NEWS: Mention new feature.
* stabs.c (stabs_generate_asm_lineno): Remember file and line number
from one call to the next, and eliminate consecutive duplicates
(thereby emitting only one line symbol per source line).
* dwarf2dbg.c (dwarf2_gen_line_info): Ditto.
final period or newline, don't say "ignored" or "zero assumed" for
as_bad messages. In some cases, change the wording to that used
elsewhere for similar messages.

ecoff.c, expr.c, frags.c, input-file.c, input-scrub.c, listing.c,
output-file.c, stabs.c, subsegs.c, symbols.c, write.c: Likewise.
* ecoff.c (ecoff_directive_end): Test for missing name by
comparing input line pointers rather than reading string.
(ecoff_directive_ent): Likewise.
* read.c (s_set): Likewise.
(s_align): Report a warning rather than an error for
alignment too large.
(s_comm): Check for missing symbol name.
(s_lcomm_internal): Likewise.
(s_lsym): Likewise.
(s_globl): Use is_end_of_line instead of looking for '\n'.
(s_lcomm_internal): Likewise.
(ignore_rest_of_line): Report a warning rather than an error.
* dwarf2dbg.c: Enabled only if BFD_ASSEMBLER is defined.
* read.h (outputting_stabs_line_debug): Change it to int.
* stabs.c (outputting_stabs_line_debug): Likewise.
(s_desc): Add ATTRIBUTE_UNUSED to args as appropriate.
* read.h (aout_process_stab): Declare.
* configure.in (EMULATIONS) [i386aout, i386coff, i386elf]:
Generalize to *aout, *coff *elf.

* doc/internals.texi (Object format backend): Say
SEPARATE_STAB_SECTIONS needs to be nonzero, not just defined.

initializations. Add casts.
* dwarf2dbg.c (print_stats): Change i to size_t.
* listing.c (listing_listing): Change list_line to unsigned int.
