I think so, altho I stay away from stdio as much as I can on embedded  
systems.

As I understand Ted's patch what one gains is control over more than  
one possible FILE for get() and put(). That would be fairly important  
for devices with more than one UART. And quite important if one built  
much of a multisession network protocol stack and hooked it in thru  
stdio.
