 When trying to compile the example code given on the Spirit web site here:
 http://boost-

 spirit.com/dl_more/parsing_tracking_position/stream_iterator_errorposition_parsing.cpp
 I ran into a "cannot convert from 'const char' to 'char &'" error when
 compiling under VS 2010 Express. The error occurred in
 split_std_dequeue_policy.hpp:69, and the following line fixes the problem:

 return const_cast< MultiPass::reference >( MultiPass::template
 get_input<Value>( mp ) );

 However using const_cast usually indicates a deeper flaw, so I'm not sure
 this is an acceptable long term fix.
