* breakpoint.c (bpstat_stop_status),

Browse Source 
infcmd.c (step_1),
	  infrun.c (wait_for_inferior): collapse SHIFT_INST_REGS ifdef and insert macro.

	* m88k-tdep.c: include ieee-float.h.  new global target_is_m88110.
	  new const struct ext_format_m88110 for float format.
	  (pic_prologue_code): add braces.
	  (next_insn): remove unused variable buf.
	  (frame_find_saved_regs): remove unused variables next_addr,
	  saved_regs, regnum.
	  (frame_locals_address): remove unused variables frame, ap.
	  (frame_args_address): remove unused variables frame, ap.
	  (push_parameters): add some breaks and a default case.

	* remote-bug.c: remove redundant includes of value.h, target.h,
	  serial.h.
	  (bug_open): corrected typo, sr_multi_scan -> gr_multi_scan.
	  (bug_fetch_register): special case sfip register for m88110.
	  remove flag bit masking of pc registers.  This should be handled
	  by the ADDR_BITS_* macros.
	  (bug_store_register): special case sfip register for m88110.
	  Corrected sprint format for extended registers.
