Here are the changes I made to my SVR2.1 system to tok.c to get things to
appear to work.  I've included just a few lines near the two ioctls that
use FIONREAD.  I've played very little, so don't know if my changes have
fixed all cases.

Also, the problem with the initializers in signal.c is because the
definition of signame[] includes signame[NSIG], which is 20 on SVR2
machines, but there are more than 20 initializers.  The approach I
took was to change the definition to "static char *signame[] = ..."
to allow the compiler to figure out how much space to allocate.

------ from tok.c ------
#ifndef SYSV
		do		/* if keyboard input buffer is too big, flush some of it */
			{
			ioctl(0,FIONREAD,&ic);
			if (ic>flushno)   read(0,&cc,1);
			}
		while (ic>flushno);
#endif

		if (read(0,&cc,1) != 1) return(lastok = -1);

		if (cc == 'Y'-64)	/* control Y -- shell escape */
			{

	..................

/*
 *	flushall()		Function to flush all type-ahead in the input buffer
 */
flushall()
	{
	char cc;
	int ic;
	for (;;)		/* if keyboard input buffer is too big, flush some of it */
		{
#ifdef SYSV
		ioctl(0,TCFLSH,0);
		return;
#else
		ioctl(0,FIONREAD,&ic);
		if (ic<=0) return;
		while (ic>0)   { read(0,&cc,1); --ic; } /* gobble up the byte */
#endif
		}
	}
