* config/sparc/xm-sun4os4.h: Define MEM_FNS_DECLARED and include

<memory.h>.
	Include <malloc.h> rather than declaring malloc functions ourself.

	* ser-unix.c (set_tty_state): Don't ignore errors setting process
	group.
	* inflow.c (terminal_inferior): If attach_flag set, ignore errors
	from set_tty_state.
