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".

Note extern is a GCC extension.
Also note that this is just size saving and nothing more.
But I will let the libstdc++ people say if this is a good idea or not.

It looks like io-inst.cc does explicitly instatiate std::iostream for char,
wchar_t.
So, they should have extern bits in the headers as well.
Fixed, thanks for reporting this.
