   spits out data in the platform's current binary format, *not* in

   code to load and store data to the resources.  Since it is unlikely 
   that we'll ever be dealing with little-endian resource data, the 
   byte-swapping nature of these macros has been disabled.  Rather than 
   remove the use of these macros from the resource loading code, the
   macros have simply been disabled.  In the future, someone may want 
   to reactivate these macros for other purposes.  In that case, the
   resource code will have to be modified to use different macros. */
