          Issue ID: 24259
           Summary: ImportC: Can use -> operator on non-pointer
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: accepts-invalid, ImportC
          Severity: minor
          Priority: P1

Found in the reduced test case of issue 24257:

```
typedef struct { int m; } S;

void f(void)
{
    S s;
    if (s->m) {}
}
```

dmd accepts, while gcc says:

```
error: invalid type argument of ‘->’ (have ‘S’)
if (s->m) {}
```
