--- Comment #6 from postmaster at raasu dot org --- There is wrong assumption again... Literal "1" is always unsigned as there is no implicit signed literals, even though there is explicit signed literals... When somebody writes "-1" it is treated as expression "0 - 1", not a literal "negative one"... This is because subtract operator has higher precedence. Empty literal always equals to literal "0".
