/* -------------------------------------------------------------------
   The basic API is described in the README file.

   The raw API is designed to bypass some of the argument packing
   and unpacking on architectures for which it can be avoided.

   The closure API allows interpreted functions to be packaged up
   inside a C function pointer, so that they can be called as C functions,
   with no understanding on the client side that they are interpreted.
   It can also be used in other cases in which it is necessary to package
   up a user specified parameter and a function pointer as a single
   function pointer.

   The closure API must be implemented in order to get its functionality,
   e.g. for use by gij.  Routines are provided to emulate the raw API
   if the underlying platform doesn't allow faster implementation.

   More details on the raw and cloure API can be found in:

   http://gcc.gnu.org/ml/java/1999-q3/msg00138.html

   and
