struct declaration and definition inside a parameter list

This is a piece of code I wrote to demonstrate passing structs as parameters.  The catch is that they are declared WITHIN the parameter list.  Which are not valid, and why they are not valid?  

Context - two compilers that I'm using can't seem to agree what is proper syntax.  One throws syntax errors.  My guess is that the one of the compilers have a bug in it.

CODE:

#include <iostream.h>

struct three_integer_struct
{
      int a;
      int b;
      int c;

      three_integer_struct
      (
            int z_a,
            int z_b,
            int z_c
      ) :
      a( z_a ),
      b( z_b ),
      c( z_c ) {};
};

void display ( three_integer_struct & data )
{
      cout << data.a <<endl <<data.b <<endl <<data.c <<endl;
}

void main()
{
      display ( (three_integer_struct) {1,2,3} );                  // Is this valid?
      display ( three_integer_struct {4,5,6} );                  // Is this valid?
      display ( three_integer_struct hello = {7,8,9} );      // Is this valid?
      display ( three_integer_struct hello {10,11,12} );      // Is this valid?
      display ( three_integer_struct (13,14,15) );            // This is valid.
}
