I have code that will compile using msvc 7.1 but will not under intel 9.0.
Here is some simplified code to illustrate my problem:
using namespace boost;
   using namespace std;
     typedef array array_type;
array_type a;
   a[0] = 0; a[1] = 1;
vector v;
   v.push_back(a);
     vector<int> h;
for_each(v.begin(), v.end(), mem_fun_ref(&array_type::front));
This compiles and runs using msvc 7.1, but intel 9.0 errors with the following:
error: more than one instance of overloaded function "mem_fun_ref"
matches the argument list:
           function template "std::mem_fun_ref(_Result (_Ty::*)() const)"
           function template "std::mem_fun_ref(_Result (_Ty::*)())"
           argument types are: (<unknown-type>)
Solution:
Don't use std::mem_fun_ref
        Use boost::mem_fn instead.

Sadly, the same problem: works with msvc 7.1 put not intel 9.0:

error: more than one instance of overloaded function "mem_fn" matches
the argument list:
            function template "boost::mem_fn(R (T::*)() const)"
            function template "boost::mem_fn(R (T::*)())"
            argument types are: (<unknown-type>)

This problem initially came up when I was using boost::bind in this way:

make_transform_iterator(v.begin(), bind(&array_type::at, _1, 0))

Intel 9.0 had these errors:

error: more than one instance of overloaded function "bind" matches
the argument list:
            function template "boost::bind(R (T::*)(B1), A1, A2)"
            function template "boost::bind(R (T::*)(B1) const, A1, A2)"
            argument types are: (<unknown-type>, boost::arg<1>, int)

Thanks,
