title: C++ frontend only compiler (convert C++ to C)
body: <p>I'm currently managing some C++ code that runs on multiple platforms from a single source tree (Win32, Linux, Verifone CC terminals, MBED and even the Nintendo GBA/DS). However I need to build an app targetted at an embedded platform for which there is no C++ compiler (C only). I remmber that many of the early C++ compilers were only front-ends stitting on existing C compilers (Glockenspiel for example used MSC). Are there any such 'frontend' C++ compilers in use today that will generate C code.</p>

  <p>The last two platforms I have good C compilers for but no C++.</p>
  
  <p>As you can see I'm supporting a large variety of platforms and I share a large body of library code (and some app code).</p>
