nitpick.

After reading Wikipedia, http://en.wikipedia.org/wiki/Data_segment

I prefer

start_data   address above program data+bss is placed.
end_data     address below program data+bss is placed
start_break  address above which program heap can be expaned with brk() call

rather than just 'data'. 

Thanks,
