[Bug libstdc++/16715] New: std::basic_iostream is instantiated when used, even though instantiations are already contained in libstdc++

["Simon dot Richter at hogyros dot de" <gcc-bugzilla at gcc dot gnu dot org>]

Hi,

I'm writing a library that extends the stream classes. Since the standard
instantiations of the iostream templates are already contained in libstdc++,
I would expect these not to be incorporated into my library (i.e. marked
"extern" in some header file). This is true for std::istream and std::ostream
(and their wide counterparts), but not for std::iostream, which is
instantiated and placed in my library.

I believe that std::iostream and std::wiostream should be marked "extern".
