Why not having both std::min and "dependent" min:

#define BOOST_EMPTY

template< class T >
inline T const & const std_min(T const &a, T const &b)
{
     return std::min BOOST_EMPTY (a, b);
}

template< class T >
inline T const & dependent_min(T const &a, T const &b)
{
     using std::min;
     return min BOOST_EMPTY (a, b);
}

possibly adding suitable workarounds for implementation that put min in 
the global namespace. I like the idea of having those as boost-wide 
utilities. I think that std_min(x, y) is nicer and more descriptive to 
read than (min)(x, y), but that's my personal taste. The separate name 
dependent_min make it self-evident even to the causal reader that it's 
something different from std::min/std_min.

Just my €0.01
