This is a bug in MSVC 7.1, I guess. You need to disambiguate:

array_type::reference (array_type::* pmf) (array_type::size_type) = 
&array_type::at;

make_transform_iterator( v.begin(), bind(pmf, _1, 0) );

Unfortunately, there is no way to tell from bind(&array_type::at, _1, 0) 
whether you need the const or non-const overload, and it is not possible to 
somehow store both overloads for later use.
