sizeof ((rehash *) 0)->again

[Norman Diamond]

According to section 3.2.2.3, page 38, an integral constant expression
with the value 0, or such an expression cast to type void *, is a null
pointer constant.  SUCH AN EXPRESSION CAST TO TYPE rehash * IS NOT CITED
IN THIS MANNER.  Section 3.3.4 says that the result has the named type,
i.e. rehash *.  Therefore the semantics of -> select a member of the
pointed-to type, and sizeof takes its size.
