Boost :

Between 1.33 and 1.33.1_beta, several classes in the serialization library
were changed from having virtual destructors to having non-virtual
destructors. An example is basic_oserializer. Many of these classes
have virtual functions, with the result that "g++ -Wall" now complains
about them ("has virtual functions but non-virtual destructor"), so that
I now get tons of warnings when compiling code that uses the serialization
library. My guess would be that none of these warnings are actually
interesting, but that belief doesn't really help all that much. Was
there a good reason for this change? Could it be reverted? If not, is
there some other thing that could be done to eliminate these warnings?
For 1.33.1 release?
