Module Name:
  memcpy.c

Abstract:

  The Microsoft compiler inlines memcpy and we can not stop it.
  These routines allow the code to link!

  There is no *.h definition of these modules as they are well known by the 
  compiler. See Microsoft documentation for more details!

  volatile is used to prevent the compiler from trying to implement these
  C functions as inline functions.
