I'm utterly dumbfounded. Not only does it boot, it's got emacs, and a compiler.

  Welcome to JS/Linux  
  ~ # emacs test.c
  ~ # cat test.c                                                                                                                                                 
  void main(void) {                                                               
      printf("Hello World!\n");                                                   
  }      
  ~ # tcc test.c -o hello                                                         
  ~ # ./hello                                                                     
  Hello World!

[Edit: just realized that there is already a 'hello.c' in the directory that shows just this with better diction.]
