[boost] [test] [iostreams] 1.47.0 VC++ 10.0 warnings

Subject: [boost] [test] [iostreams] 1.47.0 VC++ 10.0 warnings

A build of 1.47.0 using VC++10.0 is producing warnings from only a few
libraries.  It would be great if these were cleared so that this
popular compiler builds Boost without warnings at the default
settings.

Thanks,
