   Templates are no problem, the C++ compiler instantiates them, and writes   
   them out in C code.   
      
   Exceptions are harder. Sure, it is doable in C, but would the resulting,   
   stack unwinding C be portable to a different compiler (IOW free of (ab)use of   
   specific ABI knowledge )?
