I think it is, indeed. The expression 

std::max( 1, traits::matrix_num_columns(a) );

is failing because of a comparison of std::ptrdiff_t and int. On my
platform, integer_t is int, which causes a 

std::max( static_cast<integer_t>(1), traits::matrix_num_columns(a) );

to fail as well. I see std::ptrdiff_t is hardcoded in matrix_traits.
Shouldn't these functions return integer_t instead of std::ptrdiff_t?

Thanks,
