Yes, it would be nice if you could do that.  However, the line as
given above is erroneous (although likely to work in many
implementations).  Either
	yourfunction ("arg1", "arg2", ... , (char *) 0);
or
	yourfunction ("arg1", "arg2", ... , (char *) NULL);
works.  If you don't believe me, I'll e-mail you a copy of Chris
Torek's articles "Why NULL is 0" and "Re: NULL etc.", the definitive
works on the subject.
