 I get the following warnings in boost/algorithm/string when using
 boost::to_upper_copy in VC9 Service Pack 2

 This happens under 1.39, it seems similar problems were addressed in the
 same source files in a previous release using BOOST_WORKAROUND, but not
 applied to the rest of the classes in the files.
