overlay and ver 7.xx

I took some old code (saved with the original version) and decided to see what happened if I compiled with 7.xx.

To my surprise I got DATA space overflow.
What I found was that there is no DATA_GROUP shown in the map and all functions have their own private space in DATA and IDATA.

What am I missing?

PS not uVision but commandline.
