I think this is correct as structure is incomplete when the instantiation of
std::pair<const int, structure> happens which is in SetMos.
Try:
#include <map>

struct structure;

typedef std::map<int, structure> mapOfStructure;

class simpleClass
{
    mapOfStructure m_mos;
    const mapOfStructure& GetMos () const { return m_mos; }
    inline void SetMos ( const mapOfStructure& v );
};

struct structure
{
    int i;
};

inline void simpleClass::SetMos ( const mapOfStructure& v )
{
  m_mos = v;
}

--- CUT ---
Which is fixes the problem as pair needs both template arguments to be complete
when SetMos is declared.  Note I think it is needed for simpleClass is also
declared really.  So moving the declaration of structure before simpleClass is
the correct fix really.
