Yes, and even with that fixed, more checks for $is_hosted are needed for stdint.h types. I have a patch for that too, but I'm not happy with it yet. The same problems with stdio.h are listed in the other bug, but the fixes suggested there are completely wrong, and the abuse is completely unacceptable.
