stdio broken in SysV?

It's hard to say.  I don't think it's reasonable for an application
to attempt such a feat, but on the other hand STDIO should behave
sensibly anyway.

-BTW the "implicit assumption" mentioned above is due to the fact that
-the array _bufendtab[] is indexed by fp->_file rather than by fp-_iob
-or built into the FILE structure itself.

I agree that this is a design error that should be fixed.
