Milestone:  To Be Determined      |   Component:  xpressive   
  Version:  Boost 1.53.0          |    Severity:  Problem

----------------------------------+-----------------------------------------
 Windows7 64bit, MS Visual Studio 2012 (VC11), build with 32bit;

 I just compiler example code in user's guide,
 "Find all the sub-strings that match a regex and step through them one at
 a time" :
     std::wstring str( L"This is his face." );
     wsregex token = +alnum;
     wsregex_iterator cur( str.begin(), str.end(), token ); //<---error
     wsregex_iterator end;
 for( ; cur != end; ++cur ) {
         wsmatch const &what = *cur;
         std::wcout << what[0] << L'\n';
 }

 compiler said undeclared identifier of "token" in
 "wsregex_iterator cur( str.begin(), str.end(), token );" !!!

 I changed the var "token" to "tt_k", it report same error still.
 The sample code compiler OK in VS2010, but fail in VS2012.
