--- Comment #4 from Sam James <sjames at gcc dot gnu.org> ---
reduced:
```
struct name_entry {
  int mode;
} traverse_trees(), *unresolved_n;

void unresolved(int i, unsigned dirmask, unsigned mask) {
  for (; i; i++) {
    mask |= 1;
    if (!unresolved_n[i].mode || unresolved_n[i].mode & 70000)
      dirmask |= i;
  }
  if (dirmask == mask)
    traverse_trees();
}
```

and yeah, sorry Richard - I can't reproduce via cross either on my build. I
wasn't aware of that configure test..
