+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.
