/****************************************************************************

  Stackless Python Internal Configuration

  Some preliminary description can be found in the draft document readme.txt

  The configuration is dependant of one #define:
  STACKLESS means that we want to create a stackless version.
  Without STACKLESS set, you will get the standard Python application.
  If STACKLESS is set, the necessary fields and initializations are
  expanded, provided that the platform/compiler is supported by special
  header files. They implement the critical assembly part.
  If your platform is configured in this file but not supported,
  you will get a compiler error.

 ****************************************************************************/

/*
 * every platform needs to define its own interface here.
 * If this isn't defined, stackless is simply not compiled in.
 * Repeat the following sequence for every platform you support...
 * ...and then write your support code and mention it in the
 * common slp_platformselect.h file.
