I don't think that it is the correct approach. The change still broke
fileno usage as the macro will return a short value and that isn't
usable. If breaking fileno users is not considered a problem the best
fix is to actually just put the real _file field into the extended area
and put -1 into _file iff the real _file is -1 or larger than 32767.
