Hi Thierry,

Thanks you but I don't know who is responsible to apply the patch.
As you are a contributor and author of ob-C, maybe you know how to proceed. 

I have identified a minor bug. When a source code block has the mode
cpp, we cannot expand the code or more precisely the code is not
expanded in the correct way because the following function is missing  

(defun org-babel-expand-body:cpp (body params)
  "Execute BODY according to PARAMS.This function calls `org-babel-expand-body:C++'."
  (org-babel-expand-body:C++ body params))


Best
