In compiling a base class b with virtual function v, I declare

	virtual int
	b::v( b* bp )
	{
		return 0;
	}

where the intent is that derived classes may have good use for bp, but
the base class represents a null case.

cfront naturally warns about the unused argument.

	Is this excessive in the case of a virtual function?  Is there
a syntax (such as omitting ``bp'') that will allow me to say ``I know
that an argument is passed, but I don't need it'' ?  With virtuals, this
might be a common situation.

	As usual, if this could better have been handled by private mail,
sill someone please let me know?
