Comment:

 I have disabled the forwarding constructors and open() overloads in
 detail/forward.hpp when the first template parameter is identical to the
 underlying device type. This is a little too broad, since it fails to
 check whether the remaining parameters are integral; I judged that device
 constructors whose first parameter is an instance of the device itself
 would be pretty rare.

 I was able to reproduce the error with VC8.0 on a 32-bit OS with this
 code:

     typedef stream<file_source> my_stream;
     my_stream s(file_source(""), (long) 100);

 The modification to forward.hpp allows the above to compile.

 See [46047]
