True, but the old license says 'any file that references this license', and
none do, which makes figuring that out non-obvious just from looking at that
part of the source tree. At first glance it looks like all the code is yours.

I grabbed a file called 'cc65-src.arc', I can't remember where from now
(some emulation site), but it claims to be the code from the 1989 compiler.

Given that I can't find anything from a cursory glance, would it be possible
for you to provide an example? Also, is there some % figure you can give me,
out of curiosity?

Well, the compiler can't go in 'main', given what you've told me, but it
sounds like the rest can go in 'contrib' (given that it's suitable for
Debian, but relies on software that's not), and the compiler dumped into
'non-free'. If you don't mind, could you CC any other replies to
debian-legal@lists.debian.org so they can be threaded in? Thanks for your time.
