cpp_regex_traits.cpp has a specialization called message_data<wchar_t>,
which contains a parser_buf<wchar_t>, which derives from
basic_streambuf<wchar_t>, that doesn't exist in libcomo. Actually, an
implicit specialization is built by the compiler for the template, but it
misses some memebers required by the standard, like gptr().

I understand that the patch is too drastic, but it was the best
non-intrusive solution I came up with. Either that, or we can introduce a
new BOOST_NO_STD_WSTREAMBUF (or at least REGEX_NO_STD_WSTREAMBUF). Do you
see better solutions?
