Um. Since you are looking for the exact signature (untested):
namespace detail {
namespace is_overloaded_adl_barrier {
typedef chr no; struct yes { no dummy[2]; };
struct no_overload {};
yes is_overloaded_impl(...); no is_overloaded_impl(const no_overload&); struct any_conversion { template<class T> any_conversion(const T&); };
no_overload atan2(any_conversion, any_conversion);
template<class T> T make();
template<class T> struct has_atan2 : mpl::bool_< sizeof(is_overloaded_impl(atan2(make<T>(), make<T>()))) == sizeof(yes)
{};
}
using is_overloaded_adl_barrier::has_atan2;

Nice! :-) I tested it and it seems to work but it's necessary to add "using std::atan2" inside is_overloaded_adl_barrier namespace else only "no_overload atan2(any_conversion, any_conversion)" is seen. Marco -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/
