Just curious, when I use certain libraries, I get compiler warnings.

Are these simply acceptable during a build, or should they be reported to somebody ?

The latest warning I'm seeing are:

Warning               4              warning C4245: 'initializing' : conversion from 'int' to 'const boost::detail::mask_uint_t<8>::least', signed/unsigned mismatch         C:\Trunk.3.1\ThirdParty\boost\crc.hpp 377
Warning               5              warning C4245: 'initializing' : conversion from 'int' to 'const boost::detail::mask_uint_t<16>::least', signed/unsigned mismatch         C:\Trunk.3.1\ThirdParty\boost\crc.hpp 400
