I'm sorry. I have been busy and it's difficult for me to comment on that
without doing some lengthy checks. I have never seen a framework that loads
main() from a library and I would need to check the standard to see if this is
legal or triggers undefined behaviour. And to understand, why there is no
other way, than to have main() in the library, I would have to study Contiki
to some extent. All this takes time which I think is at the moment is better
spent on cc65.

It's not worse than what happened before the change. If someone forgot to link
in the startup code (which in my eyes is a lot easier than having a typo in
"main"), he got exactly the error messages you're complaining about. This is
now fixed. Yes, you're right, there are still things that could be improved.
It's all a question of importance. For now, I can live with the described
behaviour, because I know it was worse before.

Breaking Contiki is more important to me, but currently I cannot tell how to
fix that problem most easily. But I will definitely not go and start making
changes to the linker before the changes to the compiler have been debugged
and are stable to some extent.
