Patch against dmd r686

If an if statement has a variable declarator, a condition is implicitly converted to bool before its value is assigned to the declared variable.  The following code doesn't compile:
--------------------
void main()
{
    if (S s = S()) {}   // (3)
}
struct S
{
    bool opCast(T : bool)() { return true; }
}
--------------------
% dmd -o- -c test.d
test.d(3): Error: cannot implicitly convert expression (S().opCast()) of type
bool to S
