+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.
