Boost C++ Libraries: Ticket #306: Visual C++ "Language Extensions" support https://svn.boost.org/trac10/ticket/306 <pre class="wiki">The following compiles under Visual C++ .Net with "Language Extensions" enabled, but it fails otherwise: #include &lt;boost/token_iterator.hpp&gt; int main() { return 0; } The received errors are: d:\Programming\boost\boost\detail\iterator.hpp(174) : error C2061: syntax error : identifier 'value_type' d:\Programming\boost\boost\mpl\aux_\preprocessed\msvc70\or.hpp(27) : error C2970: 'boost::mpl::aux::or_impl' : template argument 'C_' : invalid use of non-integral-constant static variable 'value' as non-type argument (and 4 more similar to the last one) How can I fix this? Any help will be appreciated.
