*                                        OS DEBUG INITIALIZATION
*
* Description: This function is used to make sure that debug variables that are unused in the application
*              are not optimized away.  This function might not be necessary for all compilers.  In this
*              case, you should simply DELETE the code in this function while still leaving the declaration
*              of the function itself.
*
* Arguments  : none
*
* Returns    : none
*
* Note(s)    : (1) This code doesn't do anything, it simply prevents the compiler from optimizing out
*                  the 'const' variables which are declared in this file.
*              (2) You may decide to 'compile out' the code (by using #ff 0/#endif) INSIDE the function 
*                  if your compiler DOES NOT optimize out the 'const' variables above.
