There's also

	sizeof (int) - 1

which is ambiguous even _with_ the parens; it means either
	(sizeof(int))-1
or
	sizeof((int)-1)

In this case, I think the ambiguity is resolved by operator precedence
(though I'm not certain, since one component - the (int) - shifts
between being an operator and being an operand between the
interpretations).  I think operator precedence even less resolves the
"* as pointer vs multiplication" question, so yours is a much better
example of why the parens around types are needed.
