The patch for PR libstdc++/14097.

[Loren James Rittle]

Richard,

Your line of argument [removed here] and patch below seems reasonable
to me.  Is there anyone associated with the change in concrete
stdio*filebuf<> implementation(s) that disapproves strongly?

Yet note that Zack and Mark make the exact same point as I about GNU
compiler extensions... ;-) Users complain when we change the concrete
implementation and that it breaks their usage of undocumented APIs
(granted your request is not very outrageous so please understand the
general point here).
