The issue is theoretical at the moment because <string> ends up
including <cstdio> anyway, thus the above can't really happen. It's true
that the above union - which by way I didn't invent - it's rather
annoying if we manage to *really* avoid including <cstdio>, which is
very big.
Currently you can't really get the error above.
Paolo.
