1480,Boost:::Spirit bug in tree_to_xml.ipp,anonymous,Hartmut Kaiser,"Following code from head revision of boost::spirit(boost repository) generate error.

    file.open(_TEXT(""output.xml""), std::ios_base::out);
    basic_tree_to_xml<char_t>(file, ast_info.trees, input);
    return 0;
}

For building I use VC8.0 and it gives errors:

1>c:\work\boost\boost_lv\boost\spirit\tree\impl\tree_to_xml.ipp(482) : error C2664: 'boost::spirit::xml::document<CharT>::document(std::basic_ostream<_Elem,_Traits> &,const CharT *,const CharT *)' : cannot convert parameter 2 from 'std::wstring' to 'const char_t *'
1>        with
1>        [
1>            CharT=char_t,
1>            _Elem=wchar_t,
1>            _Traits=std::char_traits<wchar_t>
1>        ]
1>        No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

I fixed some bugs in tree_to_xml.ipp and check basic_tree_to_xml() on my tests, it seems work right.
