6.5.3 shows (the relevant parts)
unary-expression:
    postfix-expression
    ....
    sizeof unary-expression
    sizeof ( type-name )

6.5.2:
postfix-expression:
    primary-expression
    ....

6.5.1:
primary-expression:
    ....
    ( expression )

As a result the parens are required for types, and acceptable for variables.
