Not 100%.  I think that it may be saying that you can't do this anymore:

  mode = (mode_t) va_arg( arg, mode_t );

I (think) it is saying that the 2nd argument to va_arg should be int not 
mode_t but I
am not 100% sure about that.  All the cases I spot offhand in newlib use 
base types.

Anyone else have ideas?
