Bad ones, those functions are *supposed* to be overloaded.  Looking at it
though, I don't think the first of these need be a template, what happens if
you change:

template <class charT>
unsigned int BOOST_REGEX_CALL re_get_message(charT* buf, unsigned int

to

unsigned int BOOST_REGEX_CALL re_get_message(wchar_t* buf, unsigned int
