I don't understand why you'd make that distinction. Why would a reasonably high warning level not be good Boost policy? Why would emitting no warnings not be good Boost policy?

I perceive you could mean either of two things by that statement: determine whether to consider all warnings from Boost code seen by users as bugs or list each potential compiler warning and indicate whether it should be considered legitimate or not. I presume you mean the former, as the latter isn't generally possible, though one could, of course, discuss the various circumstances that would trigger particular warnings that should be treated as a bug.

I take that to mean a reporting mechanism to ensure that the author/maintainer of a library is alerted to warnings occurring on the trunk.

I suppose that you mean to imply the reporting mechanism above and a policy to disallow code so reported in a release. If so, I agree.

I'm not sure quite what you mean or how you would impose this.
