/***************************************************************************
***
***  This file uses the auto initialization possibilities of Dice, gcc and
***  SAS/C, respectively.
***
***  Dice does this by using the keywords __autoinit and __autoexit, SAS
***  uses names beginning with _STI or _STD, respectively. gcc uses the
***  asm() instruction, to emulate C++ constructors and destructors.
