There was a discussion about these warnings recently.
One possible solution is to place constants like the following in one of 
the boost headers.

__extension__ unsigned long long const ullong_max =  
~static_cast<unsigned long long>(0);
__extension__ long long const llong_max = ullong_max >> static_cast<long 
long>(1);
__extension__ long long const llong_min = -llong_max - static_cast<long 
long>(1);
