Subject: [PATCH] 	* h8500-tdep.c (initialize_h8500_tdep, large_command):
 	All references to value changed to value_ptrlage_command is now 
 called big_command. 	All references to value changed to value_ptr. 	*
 remote-z8k.c (e7000_wait): Use target_waitstatus and SETSTOP 	* remote-hms.c
 (hms_wait): Timeout after five seconds. 	* ser-go32.c (dosasync_read):
 Poll if timeout < 0. 	* config/tm/tm-h8500.h (BEFORE_MAIN_LOOP_HOOK):
 Deleted. 	* config/sh/tm-sh.h (BREAKPOINT): Is now sleep opcode.
