The lines you cite can actually be generated by the memory layout tool

We do not have a firm schedule for the implementation of MLT functionality 
in the wxWindows configuration tool at present. However, we wish to 
maintain consistency in all the MLT-related files to ensure easy transition 
to new MLT functionality in the future. It is therefore not appropriate to 
add arbitrary code to the .ldi and .h files.
