I'm not sure how other systems handle it, but Ultrix does not like fclose()
being called with a NULL pointer as an argument.  Here is a patch to fix
the file "dissect.c":

      if ((!strncmp (line, "From ", 5)) && (*last == '\n')) {
        flag++;
        if (!onlycount) {
! 	(void) fclose (to);
  	(void) strcpy (name, line+5);
  	for (cp = name; (*cp != ' ') && (*cp != '@') && (*cp != '%'); cp++);
  	*cp = '\0';
