title: Where can I get the C VERSION of go-lang source code?
body: <p>As I know, go-lang is <strong>written by C at the beginning</strong>, and now it is written by itself. I want to figure out some fundamental implementations of go-lang, such as multi-return-value-of-function, which probably use structure I guess.</p>
  
  <p>But now the go-lang version of go-lang source code has conceal these details, so where can I get the <strong>C version of go-lang source code (history version)</strong>? I've checked golang.org, nothing found.</p>
  
  <p>Thanks. </p>
