You could adjust the bit area up in memory (rather than from 20-2f) to 2A-2F. That would make the gap grow by 10 more bytes. The linker could then fit a a larger segment into the gap.
a VERY cumbersome workaround, it would "blow up in your face when you added a few variables that happened to go in the segment that you made room for by moving the bit data up.

I rallly think this is an issue Keil should consider "fixing" since DATA space is the most precious commodity in the '51.

For now I'll stick with the workaround I found of declaring some "well known and stable" DATA variables in a separate segment in assembler.
