It would be more than annoying, it would be awful, because would be also
emitted to end users of the library, not only at library build time.

So... As I see the issue, either we come up with an actual miscompilation
caused by the punning, or we have to apply the hack, for this library ABI. I'll
try to think a bit more about the issue, then, in a few days we should make a
decision...
