Some more gcc lint, and:
* read.c (change_to_section): Removed. This is now done by
subseg_new.
(get_stab_string_offset): Rearranged somewhat. Create the section
using subseg_new. Store the string index in seg_info, rather than
in a static variable. Force the first string to be empty. Use
frag_more rather than FRAG_APPEND_1_CHAR.
(s_stab_generic): Rewrote.
* subsegs.h (segment_info_type): Added stabu union.
* subsegs.c (subseg_new): Initialize stab_string_size to 0.
* config/obj-aout.c: Don't include aout/stab_gnu.h.
(obj_aout_stab, obj_aout_desc): Removed.
(obj_pseudo_table): Removed desc and stabX entries.
* config/obj-bout.c: Same changes as config/obj-aout.c.
* config/obj-bout.h (S_SET_TYPE): Define.
(tc_bout_fix_to_chars): Declare.
* config/obj-coff.c (obj_coff_stab): Removed.
(obj_pseudo_table): Removed desc and stabX entries.
* config/obj-coff.h (SEPARATE_STAB_SECTIONS): Define.
* config/obj-coffbfd.c (current_stab_symbol): Removed.
* config/obj-coffbfd.h (obj_symbol_type): Removed n_strx, n_type,
n_other, n_desc and n_value fields.
(S_{S,G}ET_{OFFSET,OTHER,TYPE,DESC}): Removed.
(MAKE_STAB_SYMBOL): Removed.
* config/obj-ecoff.c (obj_ecoff_stab): Renamed to ecoff_stab.
Changed arguments and removed parsing code.
(obj_pseudo_table): Removed stabX entries.
* config/obj-ecoff.h (ecoff_stab): Declare.
(OBJ_PROCESS_STAB): Define.
* config/obj-elf.c: Don't include aout/stab_gnu.h.
(obj_elf_stab, obj_elf_xstab, obj_elf_desc,
elf_stab_symbol_string, elf_stab_symbol, obj_elf_stab_generic):
Removed.
(obj_pseudo_table): Removed desc, stabX and xstabs entries.
(obj_elf_version): Use subseg_new, not bfd_make_section. Don't
set SEC_LOAD for .note section.
(adjust_stab_sections): Get frag pointer from seg_info, rather
than looking through frags.
* config/obj-elf.h (S_{S,G}ET_{OTHER,TYPE,DESC}): Removed.
(SEPARATE_STAB_SECTIONS, INIT_STAB_SECTION, OBJ_PROCESS_STAB):
Define.
* config/obj-vms.c (obj_aout_stab): Removed.
(obj_pseudo_table): Removed stabX entries.
* config/obj-vms.h (S_SET_TYPE): Define.
