* subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set.
Wrote non-BFD_ASSEMBLER subseg_new. Now subseg_new always takes a section name, and subseg_set always takes a segT. Changed all callers as appropriate. * config/obj-coffbfd.c (change_to_section): Renamed to obj_coff_add_segment. Corrected. Made callers use subseg_new. * config/obj-coffbfd.h (obj_segment_name, obj_add_segment): Define. Also some more gcc warning removal.

+ * read.c (s_desc): Only compile and use if S_SET_DESC is defined.
+ * struc-symbol.h: Declare verify_symbol_chain and
+ verify_symbol_chain_2 even if not SYMBOLS_NEED_BACKPOINTERS.
+ * symbols.c (verify_symbol_chain): Removed useless expression.
+ * write.c (headers, the_object_file): Only use if not
+ BFD_ASSEMBLER and not BFD.
+ (fixup_segment, cvs_frag_to_fill): Only use if BFD_ASSEMBLER or
+ not BFD.
+ (merge_data_into_text): Only use if BFD_ASSEMBLER or (not BFD and
+ not OBJ_AOUT).
+ * write.h: Declare relax_segment.
+ * config/obj-coffbfd.c (stack_pop, stack_push, stack_init): Made
+ static.
+ (stack_top): Commented out, since it's not used.
+ Fixed up pseudo-op functions to take an ignored int argument.
+ (size_section): Added default BAD_CASE to switch.
+ Changed bzero calls to memset.
+ * config/obj-coffbfd.h (S_IS_LOCAL): Call strchr on S_GET_NAME
+ (s), not on s itself.
+ * config/tc-a29k.c (s_use): Take ignored int argument. Only
+ define if OBJ_COFF is not defined.
+ * config/tc-i386.c: (fits_in_signed_byte, smallest_imm_type): Make
+ argument signed again.
+ * config/tc-m68k.c (s_bss, s_even, s_proc): Take ignored int
+ argument.
+ (m68k_ip): Fully bracket initialization of archs.
+ Correct several formats for __LINE__ to be %d rather than %s.
+ (init_table): Fully bracket initialization.
+ Cast values larger than 0x7f assigned to fr_opcode to char.
+
+ * subsegs.c: Renamed non-BFD_ASSEMBLER subseg_new to subseg_set.
+ Wrote non-BFD_ASSEMBLER subseg_new. Now subseg_new always takes a
+ section name, and subseg_set always takes a segT. Changed all
