           Summary: ImportC: .di generator outputs C expression with `->`
                    operator

C code:

struct foo {
    int x;
};
typedef int weird[sizeof(((struct foo *)((void*)0))->x)];

outputs:

extern(C)
{
  // ...
        struct foo
        {
                int x = void;
        }
        alias weird = int[(cast(foo*)cast(void*)0)->x.sizeof];
  // ...
}

Encountered something like this in an SDL header.
