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?
Thanks
