For information, I am testing this on debian packages right now. I will see the
results next week.

I forgot to remove this FIXME comment, I will remove it.

Imho this is a clumpsy way to see if it's a "multivariable" declaration. Do you
know if there is a better way?

Is there a better way to rewrite this ... I tried something like this without
success:
```
auto D = diag(..);
if (!MultiVar)
D << FixItHint..;
```

Ideally this would be changed to "extern int B;". I currently don't fix
multivariable declarations.
