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.
