[Boost-users] Xcode 4.5 and boost 1.51.0 semantic issues with implicit conversions long to int

Recently upgraded to Xcode 4.5 and boost 1.51 and started getting a pile of: /Users/grahamreitz/Development/src/libs/boost_1_51_0/boost/asio/detail/impl/socket_ops.ipp:952:20: Implicit conversion loses integer precision: 'size_t' (aka 'unsigned long') to 'int' ...warnings I'm guessing this is a 64 bit/32 bit issue. Should I be seeing these warnings out of the box?
