I'm going to ask you to think again about that assessment, because
'implicit extern C' mode is actually trouble if the headers *are* C++
aware -- look back through the bug database for cases. And my
suspicion is that nowadays, the headers that generic targets do have
are more likely to be C++ aware than not.
