I'm sorry, but I have to contradict this. At one time I did have the idea to implement it, but have never made it that far. The define _gptrget.c is not SDCC_MODEL_MEDIUM but has an extra D (DSDCC_MODEL_MEDIUM) (disabled). If I had implemented this I certainly would have put it in the manual. I still think it's a good idea though and maybe one day in the future...
