I get the following error when trying to use the filesystem library on MSVC 6.0 : error C2061: syntax error : identifier 'BOOST_DEDUCED_TYPENAME' The line causing the problem is in the \detail\iterator.hpp file: template <class T> type_traits::yes_type is_mutable_iterator_helper(T const*, BOOST_DEDUCED_TYPENAME T::value_type*); I have run a config Test and both BOOST_DEDUCED_TYPENAME and BOOST_NO_DEDUCED_TYPENAME are defined but have no value. Since MSVC 6.0 supports the 'typename' keyword I would think that the declaration above in the iterator.hpp file should use 'typename' rather than BOOST_DEDUCED_TYPENAME. Anyone else experience this problem? ******************************************************************************************* http://www.intec-telecom-systems.com/ This e-mail and any attachments are confidential and may also be privileged and/or copyright material of Independent Technology Systems Limited (or its affiliated companies).
