9  * Before tree.c 1.137 from 2021-01-19, taking the complement of a struct
10  * (an absurd idea, by the way), resulted in an internal error because the
11  * message 108 took two type operands, the second of which was not available
12  * for unary operators.
13  *
14  * Since an error "invalid type 'none'" doesn't make sense, lint rather chose
15  * to crash than to generate such an error.
