* remote-monitor.c: updated copyright.

(bug_ops, monitor_desc): now static.
	  (monitor_desc): in several places, check and/or set to NULL.

	* remote-hms.c (hms_files_info): Add the appropriate items where
	  missing in the printf call.

	* remote-bug.c: new file for m88k bug support.

	* config/m88k/m88k.mt (TDEPFILES): added remote-bug.o.
