Comment (by Richard Webb <richard.webb_at_[hidden]>):

 Running the ios tests on VC9 with warning level 4 results in the warnings:

 {{{
 boost/io/ios_state.hpp(131) : warning C4512:
 'boost::io::basic_ios_iostate_saver<Ch>' : assignment operator could not
 be generated

 }}}

 Some of the classes in ios_state.hpp already have private assignment
 operators, which avoids this warning. The attached patch adds them to the
 other classes, and silences the rest of the warnings.
