This is more complicated than it looks, because some standard libraries declare do_length as:
        ‘virtual int do_length(mbstate_t&, const char*, const char*, size_t) const’
and others as:
        'virtual int do_length(const mbstate_t&, const char*, const char*, size_t) const’

This was changed in the C++ standard back about the 2004 (changed TO const mbstate_t)
but the Dinkumware library shipped with Visual Studio (for one) was not updated until very recently.
[ I believe that it is changed for VS 2013 ]

I tried to fix this once - I broke one of the serialization tests.
Robert Ramey has been looking into this as well.
