    ABSTRACT
    Contains support functions that are OS / Platform dependent.
    This file should be in the platform specific directories,
    However most platforms can use this file exactly as it is,
    so this file is kept in the common area.
    Platforms that require these functions to be overridden can
    ignore this file and make a local platform specific copy in 
    the platform specific directory.
