Well, bzero, bcopy, and bcmp are expected to be provided by the host
system.  If you don't have one, I suspect you don't have any.  Here
are thumbnail versions, not particularly optimized for anything:

void bzero(void *b, size_t len)
{
	unsigned char *t = (unsigned char *)b;

	do {
		t[--len] = '\0';
	} while (len != 0);
}

/* Copies src to dst, taking overlap into account */
void bcopy(const void *src, void *dst, size_t len)
{
	unsigned char *csrc = (unsigned char *)src;
	unsigned char *cdst = (unsigned char *)dst;

	if (src > dst) {
		do {
			len--;
			cdst[len] = csrc[len];
		} while (len != 0);
	} else {
		size_t count;
		for (count = 0; count < len; count++) {
			cdst[count] = csrc[count];
		}
	}
}

/* Compares len bytes starting at b1 to the len bytes starting at b2.
 * Returns < 0 for b1 < b2, == 0 for b1 == b2, and > 0 for b1 > b2.
 */
int bcmp(const void *b1, const void *b2, size_t len)
{
	unsigned char *left = (unsigned char *)b1;
	unsigned char *right = (unsigned char *)b2;
	int retval;
	size_t count;

	for (count = 0; count < len; count++) {
		retval = *left - *right;
		if (retval != 0)
			return (retval);
	}

	return 0;
}

Bleah.  Not knowing anything about the C environment on a LispM, my
suggestion would be that, if there's a way to compile the above and
link it with what you've already got, that'd be the way to go.
