/* This file declares the new abi entry points into the runtime. It is not
   normally necessary for user programs to include this header, or use the
   entry points directly. However, this header is available should that be
   needed.
   
   Some of the entry points are intended for both C and C++, thus this header
   is includable from both C and C++. Though the C++ specific parts are not
   available in C, naturally enough.  */
