I don't have the compiler, but my guess is it's probably actually confused
on the line:
typedef size_t type;
A simple workaround to try could be to change the typedef to:
typedef mpl::size_t<N> type;
If that fix works, I'd be surprised if such a change would break any other
compilers. This is all just a guess, though.
