Since I was not entirely sure about your answer I tried out the following


 second \$\$\(\SS*?\)\$\$, works in GNU emacs but not in Xemacs
 third \$\$\(.\|^J*?\)\$\$ does not work in both
 forth \$\$\(\(.\|^J\)*?\)\$\$ does not work in both


Ok this means there is one working solution for GNU emacs but not for
Xemacs.
