call non-const function

GFXMLTree* Seek4Node(LPCTSTR name);
const GFXMLTree* Seek4Node(LPCTSTR name) const
{
return Seek4Node(name); // Force to call the first version

GFXMLTree* Seek4Node(LPCTSTR name);
const GFXMLTree* Seek4Node(LPCTSTR name) const
{
return Seek4Node(name); // Force to call the first version
}

You can only safely do that if you know that your object was in fact
non-const when it was created. But that's only known by the caller,
not inside the function. So, before calling the overloaded member
function, cast the constness away.
