This was removed from the libstdc++ sources erroneously, and I just 
re-added it. It should appear in your sources, if they are up-to-date, 
in include/ext/enc_filebuf.h. If not, there's something wrong.

If you are working on a branch or have sticky tags you may have to do 
the appropriate gymnastics.
