Did they miss the part about the fallback permissive license? I'm
pretty sure Solar's implementation of bcrypt (albeit the original, not
the one he modified for musl) is used in plenty of other places with
no problem. Complaining about copyright status on this is like
complaining about fdlibm. If it's really a problem I suspect he would
be willing to clarify its status for you.

I don't understand why they're making a meal of this again. This is
covered under the code I already said I would contact the contributors
for clarification on, which I'm happy to do once I get feedback that
the changes will meet your needs. Is the problem just that I forgot to
remove this text and replace it with a statement that the port was
contributed by Nicholas J. Kain under the project's license terms? I
can certainly do that assuming I get the clarification we discussed.
In any case the only original crt files left from this contribution
are crti/crtn which are literally _single instruction_ functions. The
idea that they could be subject to copyright (even if some of the
other things we claimed were PD were more iffy) is utterly absurd.
(All crt1.s were removed a while back and replaced by the unified C
version; the new crt_arch.h files they used are mostly original works
by me.)

This really seems like the most natural place for this content so that
interested readers have access to it. I'm really trying to work with
you guys here, and it's frustrating when your lawyers come back with
complaints about statements of opinion/belief that are clearly
disjoint from license terms and that explicity state that they are not
to be interpreted as affecting the license. Other well-known licenses
(especially the GPL and LGPL) contain statements of belief and similar
that are not legally binding, even statements of legal theories like
"You are not required to accept this License..."
If this is still bothering them, would it make them happy to put some
"end of legal text" marking above that paragraph?
