I've took the liberty of comitting the following change, which make "m_value" visible on compilers with two-phase lookup (like gcc 3.4) However, the token_iterator_test still fails to compile on 3.4 saying: token_iterator_test.cpp:47:38: converting to execution character set: Invalid or incomplete multibyte or wide character token_iterator_test.cpp:48:31: converting to execution character set: Invalid or incomplete multibyte or wide character token_iterator_test.cpp:48:42: converting to execution character set: Invalid argument token_iterator_test.cpp:48:49: converting to execution character set: Invalid argument token_iterator_test.cpp:48:55: converting to execution character set: Invalid or incomplete multibyte or wide character Looks like the text in L"" literals is not 7-bit, and that's why compiler errors out. Is it possible to change the test somehow? - Volodya Index: token_iterator.hpp =================================================================== RCS file: /cvsroot/boost/boost/boost/test/detail/iterator/token_iterator.hpp,v retrieving revision 1.3 diff -u -r1.3 token_iterator.hpp --- token_iterator.hpp 19 Jul 2004 12:29:57 -0000 1.3 +++ token_iterator.hpp 20 Jul 2004 12:45:47 -0000 @@ -309,7 +309,7 @@ typedef ut_detail::token_assigner<BOOST_DEDUCED_TYPENAME iterator_traversal<Iter>::type> Assigner; Iter checkpoint; - Assigner::clear( m_value ); + Assigner::clear( this->m_value ); if( !m_keep_empty_tokens ) { while( begin != end && m_is_dropped( *begin ) )
