Subject: numerous warnings in Thread library in 1.30.0 release when compiled by VC7.1 (or other vc versions) with warning level 3 or above We're in the process of migrating our project from V1.29.0 to 1.30.0. We are getting a lot of warnings with thread library such as the following: c:\Program Files\Boost\boost\thread\condition.hpp(38) : warning C4275: non dll-interface class 'boost::noncopyable' used as base for dll- interface class 'boost::detail::condition_impl' I know very little about bjam but it looks like it doesn't even use /Wn switch (correct me if I am wrong and the default is /W2. IMHO, it seems to me that it is always a good practice to set the warning level to at least 3. Also, we would really really like to have the static library option back. :-) Best regards, Sean
