>From fail_compilation/fail91.d

struct S;

void main()
{
    S* s = new S();
}

Prints:
fail_compilation/fail91.d(13): Error: struct fail91.S unknown size
fail_compilation/fail91.d(13): Error: struct fail91.S no size yet for forward
reference

However, "no size yet for forward reference" is a wrong message, because opaque
struct size never be calculated during compilation.

So, the code should print:
fail_compilation/fail91.d(13): Error: struct fail91.S unknown size
