I can't reproduce any of the warnings, but I've made a change to chain.hpp that I hope will fix the first warning. (See [45781]). Please check to see that the problem is fixed. I'm not sure why the code was written the way it was -- possibly it was to make the library work with VC6.0 or an old version of Borland.

As for the two unused parameter warnings, I take these seriously, but I can't find the unused 't' in the first warnings, and the parameter 'comment' from the second warning does appear to be used. What version of Boost are you using (I know the ticket says 1.35.0, but that seems to be the default value)?

I'm going to close this, since the first warning is pretty clear, even though I can't reproduce it, and the change to chain.hpp addresses it directly. I believe I have fixed all the unreferenced parameter warnings in response to other tickets.
