------- Comment #5 from janis at gcc dot gnu dot org  2008-09-19 18:24 -------
The operand of a postincrement and friends must be a modifiable lvalue.  The
type check code for both C and C++ calls get_unwidened, which removes the cast
when it's a different size but leaves the cast when it's the same size.  The
later call to lvalue_p (via lvalue_or_else) says the operand is not an lvalue
when there's still a cast, but doesn't complain when the cast has been removed.
