   Status:  new        |   Milestone:  To Be Determined

 Severity:  Problem    |    Keywords:                  
-----------------------+----------------------------------------------------
 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>

 1>        ]
 1>        No user-defined-conversion operator available that can perform

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