	( expr )
is also an
which is why
	return( expr );
is legal although the definition is
	return expr;
However, stylistically I recommend leaving unnecessary parentheses off
the return expr since, as I said, they make it look like a function call.
Both ways are legal and this wouldn't be an important issue except that
some C compilers (apparently the DECUS C compiler) do not accept the
more general form.
