sizeof is always a unary operator keyword, never a function name.
It can be validly used in two distinct ways:
	sizeof unary_expression
	sizeof ( type_name )

Some people put parentheses around the innards of their unary_expression,
but they are not required.  (Same as for the operand of "return".)
