Many thanks for confirming what I thought, and dreaded... There was no
section called 'common' or 'com' or anything else for that matter, just the
normal '.code', '.data' etc etc.
I presume this means I need to either :
1. establish the size of the *com* section from entry addresses and sizes,
or
2. somehow force all such entries into the .bss section...
Cheers
