Hi,my friends I have a stupid question Now i build boost 1.49 on x64 platform with vc2005 I find such many warnings: warning C4267: '=' : conversion from 'size_t' to 'unsigned int', possible loss of data or conversion from '_int64' to 'unsigned int', possible loss of data I want to make sure that these warnings really do lose data whether or not on x64 flatform. Put another way, could these warning be neglected or should i change the source code?

Showing the code is causing this warning may help. Best, Vicente
