Hi guys,

as you are aware of, naming the sections is not the real problem.
Also relocated .text sections will cause problems. More serious is the
16-bit address limitation.

What is the real problem here?
- the DWARF/2 specs?
- The gcc DWARF output?

This is interesting, since the larger devices are perhaps the ones most
often equipped with bootloaders :)

Best regards,
Eivind
