This is unnecessary, given this:
+Warn about casting from/to incomplete types
Yes, the test is a bit of defensive programming and is redundant in a
couple of ways. Perhaps I'm too paranoid for my own good; I will
remove it unless somebody objects.
I think it should only warn about casting from/to ptr/ref to
an incomplete type from/to a ptr/ref to another class type. Otherwise there
is no way to silence false positives, and (void *)ptr is ok anyway.
