Hi John,

Thanks for the reply.

I did check that both
    boost/function/function1.hpp and    
    boost/function/detail/function_iterate.hpp
do indeed define BOOST_FUNCTION_NUM_ARGS (without #ifndef or #undef).

I did also note that the new/fixed version of 
boost/function/function_base.hpp includes the <functional> header (where 
the old version did not) and of course that's where the new TR1 function 
classes reside when TR1 is included.

Robert.
