I have one last quick question, I have an exmaple here with no-web that
I think should work but doesnt. I wonder why:

    #+BEGIN_SRC C :noweb-ref begin
    int main() {
      printf("Line 1\n");
    
    #+END_SRC
    
    #+BEGIN_SRC C  :noweb-ref middle
    printf("Second\n");
    #+END_SRC
    
    #+BEGIN_SRC C  :noweb-ref end
    }
    main();
    #+END_SRC
    
    
    #+BEGIN_SRC C  :noweb yes
    
        <<begin>>
        <<middle>>
        <<end>>
        printf("some appropriate debug word");
    
 
    #+END_SRC
    
    And the output is:
    /tmp/babel-15080Ms4/C-src-150805OE.c: In function ‘main’:
    /tmp/babel-15080Ms4/C-src-150805OE.c:6:7: warning: incompatible implicit 
declaration of built-in function ‘printf’
           printf("Line 1\n");
           ^
    /tmp/babel-15080Ms4/C-src-150805OE.c: At top level:
    /tmp/babel-15080Ms4/C-src-150805OE.c:10:5: warning: data definition has no 
type or storage class
         main();
         ^
    /tmp/babel-15080Ms4/C-src-150805OE.c:12:8: error: expected declaration 
specifiers or ‘...’ before string constant
     printf("asti");
            ^
    /bin/bash: /tmp/babel-15080Ms4/C-bin-15080GZK: Permission denied

Or if I dont include the 

    printf("some appropriate debug word");

then, I get no output at all.

    `Code block produced no output.`


So my question is how do I make this work. lol.
    

Thanks in advance again
