       #include	"mut.h"
       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);
		}
	     }
