Hello,
I'm not really sure but isn't there a friend declaration missing in the 
fixed_mapping class?
Given the following code:
template< ... >
class fixed_mapping
{
     typedef std::pair<Key,Value> elem_type;
     ...
     struct p1 : public std::binary_function<elem_type,Key,bool>
     {
         bool operator()( elem_type const& x, Key const& y ) const
         { return Compare()( x.first, y ); }
     };
     ...
};
doesn't this require p1 to be a friend of fixed mapping to be able to 
access elem_type in it's operator()?
Strictly, yes.  But many compilers implement the resolution to DR45
already:
