check(p)
losig_list *p;
{
char *amatla;
losig_list *ptsig;
locon_list *ptcon;
ht *h;
	for (i = 0, ptsig = p->LOSIG; ptsig; i++, ptsig = ptsig->NEXT);
	h = addht(i);
	/* two connectors can't have the same name! */
	for (ptcon = p->LOCON; ptcon; ptcon = ptcon->NEXT)
		addhtitem(h, ptcon->NAME, 0);
	for (ptsig = p->LOSIG; ptsig; ptsig = ptsig->NEXT) {
		if (ptsig->TYPE == INTERNAL) {
			amatla = getsigname(ptsig);
			/* this is nicely done with sethtitem! */
			if (gethtitem(h, amatla) == EMPTYHT) { 
				printf("N %s;\n", amatla);
				addhtitem(h, amatla, 0);
			}
		}
	}
	delht();
