[Boost-users] resetting FUSION_MAX_MAP_SIZE

Hi there, I'm experiencing problems when setting FUSION_MAX_MAP_SIZE
to 20. I'm getting a lot of compiler errors:

#define FUSION_MAX_MAP_SIZE 20

#include <string>

#include <boost/static_assert.hpp>
#include <boost/fusion/sequence.hpp>

using namespace std;
using namespace boost;

// Address contact
namespace address_fields
{
        struct _address_1_;
        struct _address_2_;
        struct _city_;
        struct _state_;
        struct _zip_;
        struct _country_;
        struct _phone_1_;
        struct _phone_2_;
        struct _email_1_;
        struct _email_2_;
        struct _fax_;
        struct _other_;
}

typedef fusion::map< fusion::pair< address_fields::_address_1_, string >
                   , fusion::pair< address_fields::_address_2_, string >
                   , fusion::pair< address_fields::_city_     , string >
                   , fusion::pair< address_fields::_state_    , string >
                   , fusion::pair< address_fields::_zip_      , string >
                   , fusion::pair< address_fields::_country_  , string >
                   , fusion::pair< address_fields::_phone_1_  , string >
                   , fusion::pair< address_fields::_phone_2_  , string >
                   , fusion::pair< address_fields::_email_1_  , string >
                   , fusion::pair< address_fields::_email_2_  , string >
                   , fusion::pair< address_fields::_fax_      , string >
                   , fusion::pair< address_fields::_other_    , string >
                   > address_type;
