Re: [boost] [serialization] codecvt_null.cpp not present in windowsdlls

The patch did not work for me.

I am trying to work out why the narrow character versions work with
dynamic linking, but the wide character versions do not.

I guess it is possible all references to these functions are
encapsulated inside the narrow char dll itself, so export is not
necessary to pass its own tests (and so bad declarations are not
exposed)
