Indenting problem

[M Wasilewski <mmw@srv.ualberta.ca>]

I seem to be having a problem with emacs indenting. Under solaris and 
linux my indenting looks like so:

Vector3 cross( const Vector3 &v ) const
{
 return Vector3( y * v.z - z * v.y,
                 z * v.x - x * v.z,
                 x * v.y - y * v.x );
}

No problems. But running emacs under Windows XP with the same .emacs file 
gives me this:

Vector3 cross( const Vector3 &v ) const
{
 return Vector3( y * v.z - z * v.y,
               z * v.x - x * v.z,
               x * v.y - y * v.x );
}

The z and the x are lined up with the bracket rather than the y. Does 
anyone know why this is? Or more importantly how to fix it?
Thanks.
