Double check that you're compiling with the switch that uses an intrinsic type for wchar_t rather than a short int.

Note that a lot of the warnings are from boost::io::state_saver... so maybe there is an issue there.

I double checked. I'm treating wchar_t as an intrinsic type. I tried changing that and didn't notice any difference in the number of warnings issued.
