allocator.cuh lots of "format '%d'" warnings

[harrism]

I created a simplified test code that reproduces this problem. I get lots of compiler warnings with CUDA 5 on Ubuntu 12.04 64-bit with this code:

#include <cub.cuh>

template <int BlockSize>
__global__ void foo()
{
    typedef cub::BlockReduce<int, BlockSize> BlockMax;
    __shared__ typename BlockMax::SmemStorage smem_storage;
    int myMax = BlockMax::Reduce(smem_storage, threadIdx.x, max);
}

int main(void)
{
    return 1;
}

Compile output and OS/compiler versions in below output.

Hi Mark, thanks for pointing this one out, also. I just committed an update to fix the issue (NVlabs@504ca9d)
