What difference between SS11 and Gcc 

 I happened to download the latest JDK in Sun website where I saw a new game called "Temple of the Sun". Fun game and at the end, after I registered with my name I saw the last question but the answer is still on the road. I started up the Cygwin and tried to compile it with gcc-3.4.3.  After some struggling with gcc, finally I could compile the codes :-) , the result is very interesting.. 

Don 'El Jefe' Kretsch says: "The key to understanding recursion is to begin by understanding recursion."

Don is the Director of SS. The text has the same sense of GNU.  Cool, isn't it.
Eventually I knew that when s.a == 1, then SS11 == Gcc :-)
