<pre>Clang incorrectly rejects this:
struct X { void operator++(int); };
void f() { (X())++; }
... because it believes the (X()) is a cast. I think this *only* goes wrong for
++ and --, where we need more than one token of lookahead past the
parenthesized type/expression.
When ParseCastExpression is called from the disambiguation code, it should call
the inner ParseCastExpression in the same disambiguation mode, and put its
token back if that call finds a non-cast-expression.
Amusingly, EDG and GCC have the same bug.</pre>
