Subject: [boost] [gil] compiler error with clang in c++11 mode

Hi there,

Can someone shed some light on the following compiler errors:

c:\boost\boost\gil/channel_algorithm.hpp:54:85: error: non-type
template argument evaluates to -1, which cannot be narrowed to type
'unsigned long long' [-Wc++11-narrowing]
struct unsigned_integral_max_value : public
mpl::integral_c<UnsignedIntegralChannel,-1> {};

c:\boost\boost\gil/channel_algorithm.hpp:204:19: note: in
instantiation of template class
'boost::gil::detail::unsigned_integral_max_value<unsigned long long>'
requested here
        if (src > unsigned_integral_max_value<uintmax_t>::value - div2)

I only get those in c++11 mode. The code to trigger them is:

#include <boost\gil\gil_all.hpp>

int main()
    return 0;

I'm using clang 3.2 on Windows with CodeBlocks.
