Dave, I meant to get back to you on the static-assertion problem you had -
basically I tried all sorts of things, and with VC6
std::numeric_limits<T>::is_integer seems to always evaluate to false at
compile time: the following also fails:
template <class T>
struct int_check1
{
typedef int (&type)[std::numeric_limits<T>::is_specialized ? 1 :
-1];
};
int_check1<int> ic1;
Strangely the problem seems to be unique to numeric_limits - the boost
type_traits classes always seem to give the right answer when fed into
static assertions. At the moment I have no idea what's going on.
