[Boost-users] integer constant too large for 'long' type

I'm having problems compiling this line of code on a 32bit system: boost::uniform_int r(0,0xffffffffffffffff); compile-time error: "integer constant too large for 'long' type" compiled fine on my 64 bit machine. Also sizeof(uint64_t) on both machines is correct at 8 bytes (typedef'd as long long int on the 32bit machine). Any ideas?
